Now You Can Create Encrypted Amazon EBS Volumes by Using Your Custom Encryption Keys When You Launch an Amazon EC2 Instance

Post Syndicated from Nishit Nagar original https://aws.amazon.com/blogs/security/create-encrypted-amazon-ebs-volumes-custom-encryption-keys-launch-amazon-ec2-instance-2/

Amazon Elastic Block Store (EBS) offers an encryption solution for your Amazon EBS volumes so you don’t have to build, maintain, and secure your own infrastructure for managing encryption keys for block storage. Amazon EBS encryption uses AWS Key Management Service (AWS KMS) customer master keys (CMKs) when creating encrypted Amazon EBS volumes, providing you all the benefits associated with using AWS KMS. You can specify either an AWS managed CMK or a customer-managed CMK to encrypt your Amazon EBS volume. If you use a customer-managed CMK, you retain granular control over your encryption keys, such as having AWS KMS rotate your CMK every year. To learn more about creating CMKs, see Creating Keys.

In this post, we demonstrate how to create an encrypted Amazon EBS volume using a customer-managed CMK when you launch an EC2 instance from the EC2 console, AWS CLI, and AWS SDK.

Creating an encrypted Amazon EBS volume from the EC2 console

Follow these steps to launch an EC2 instance from the EC2 console with Amazon EBS volumes that are encrypted by customer-managed CMKs:

  1. Sign in to the AWS Management Console and open the EC2 console.
  2. Select Launch instance, and then, in Step 1 of the wizard, select an Amazon Machine Image (AMI).
  3. In Step 2 of the wizard, select an instance type, and then provide additional configuration details in Step 3. For details about configuring your instances, see Launching an Instance.
  4. In Step 4 of the wizard, specify additional EBS volumes that you want to attach to your instances.
  5. To create an encrypted Amazon EBS volume, first add a new volume by selecting Add new volume. Leave the Snapshot column blank.
  6. In the Encrypted column, select your CMK from the drop-down menu. You can also paste the full Amazon Resource Name (ARN) of your custom CMK key ID in this box. To learn more about finding the ARN of a CMK, see Working with Keys.
  7. Select Review and Launch. Your instance will launch with an additional Amazon EBS volume with the key that you selected. To learn more about the launch wizard, see Launching an Instance with Launch Wizard.

Creating Amazon EBS encrypted volumes from the AWS CLI or SDK

You also can use RunInstances to launch an instance with additional encrypted Amazon EBS volumes by setting Encrypted to true and adding kmsKeyID along with the actual key ID in the BlockDeviceMapping object, as shown in the following command:

$> aws ec2 run-instances –image-id ami-b42209de –count 1 –instance-type m4.large –region us-east-1 –block-device-mappings file://mapping.json

In this example, mapping.json describes the properties of the EBS volume that you want to create:


{
"DeviceName": "/dev/sda1",
"Ebs": {
"DeleteOnTermination": true,
"VolumeSize": 100,
"VolumeType": "gp2",
"Encrypted": true,
"kmsKeyID": "arn:aws:kms:us-east-1:012345678910:key/abcd1234-a123-456a-a12b-a123b4cd56ef"
}
}

You can also launch instances with additional encrypted EBS data volumes via an Auto Scaling or Spot Fleet by creating a launch template with the above BlockDeviceMapping. For example:

$> aws ec2 create-launch-template –MyLTName –image-id ami-b42209de –count 1 –instance-type m4.large –region us-east-1 –block-device-mappings file://mapping.json

To learn more about launching an instance with the AWS CLI or SDK, see the AWS CLI Command Reference.

In this blog post, we’ve demonstrated a single-step, streamlined process for creating Amazon EBS volumes that are encrypted under your CMK when you launch your EC2 instance, thereby streamlining your instance launch workflow. To start using this functionality, navigate to the EC2 console.

Tag Amazon EBS Snapshots on Creation and Implement Stronger Security Policies

Post Syndicated from Woo Kim original https://aws.amazon.com/blogs/compute/tag-amazon-ebs-snapshots-on-creation-and-implement-stronger-security-policies/

This blog was contributed by Rucha Nene, Sr. Product Manager for Amazon EBS

AWS customers use tags to track ownership of resources, implement compliance protocols, control access to resources via IAM policies, and drive their cost accounting processes. Last year, we made tagging for Amazon EC2 instances and Amazon EBS volumes easier by adding the ability to tag these resources upon creation. We are now extending this capability to EBS snapshots.

Earlier, you could tag your EBS snapshots only after the resource had been created and sometimes, ended up with EBS snapshots in an untagged state if tagging failed. You also could not control the actions that users and groups could take over specific snapshots, or enforce tighter security policies.

To address these issues, we are making tagging for EBS snapshots more flexible and giving customers more control over EBS snapshots by introducing two new capabilities:

  • Tag on creation for EBS snapshots – You can now specify tags for EBS snapshots as part of the API call that creates the resource or via the Amazon EC2 Console when creating an EBS snapshot.
  • Resource-level permission and enforced tag usage – The CreateSnapshot, DeleteSnapshot, and ModifySnapshotAttrribute API actions now support IAM resource-level permissions. You can now write IAM policies that mandate the use of specific tags when taking actions on EBS snapshots.

Tag on creation

You can now specify tags for EBS snapshots as part of the API call that creates the resources. The resource creation and the tagging are performed atomically; both must succeed in order for the operation CreateSnapshot to succeed. You no longer need to build tagging scripts that run after EBS snapshots have been created.

Here’s how you specify tags when you create an EBS snapshot, using the console:

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
  2. In the navigation pane, choose Snapshots, Create Snapshot.
  3. On the Create Snapshot page, select the volume for which to create a snapshot.
  4. (Optional) Choose Add tags to your snapshot. For each tag, provide a tag key and a tag value.
  5. Choose Create Snapshot.

Using the AWS CLI:

aws ec2 create-snapshot --volume-id vol-0c0e757e277111f3c --description 'Prod_Backup' --tag-specifications 
'ResourceType=snapshot,Tags=[{Key=costcenter,Value=115},{Key=IsProd,Value=Yes}]'

To learn more, see Using Tags.

Resource-level permissions and enforced tag usage

CreateSnapshot, DeleteSnapshot, and ModifySnapshotAttribute now support resource-level permissions, which allow you to exercise more control over EBS snapshots. You can write IAM policies that give you precise control over access to resources and let you specify which users are able to create snapshots for a given set of volumes. You can also enforce the use of specific tags to help track resources and achieve more accurate cost allocation reporting.

For example, here’s a statement that requires that the costcenter tag (with a value of “115”) be present on the volume from which snapshots are being created. It requires that this tag be applied to all newly created snapshots. In addition, it requires that the created snapshots are tagged with User:username for the customer.

{
   "Version":"2012-10-17",
   "Statement":[
      {
         "Effect":"Allow",
         "Action":"ec2:CreateSnapshot",
         "Resource":"arn:aws:ec2:us-east-1:123456789012:volume/*",
	   "Condition": {
		"StringEquals":{
               "ec2:ResourceTag/costcenter":"115"
}
 }
	
      },
      {
         "Sid":"AllowCreateTaggedSnapshots",
         "Effect":"Allow",
         "Action":"ec2:CreateSnapshot",
         "Resource":"arn:aws:ec2:us-east-1::snapshot/*",
         "Condition":{
            "StringEquals":{
               "aws:RequestTag/costcenter":"115",
		   "aws:RequestTag/User":"${aws:username}"
            },
            "ForAllValues:StringEquals":{
               "aws:TagKeys":[
                  "costcenter",
			"User"
               ]
            }
         }
      },
      {
         "Effect":"Allow",
         "Action":"ec2:CreateTags",
         "Resource":"arn:aws:ec2:us-east-1::snapshot/*",
         "Condition":{
            "StringEquals":{
               "ec2:CreateAction":"CreateSnapshot"
            }
         }
      }
   ]
}

To implement stronger compliance and security policies, you could also restrict access to DeleteSnapshot, if the resource is not tagged with the user’s name. Here’s a statement that allows the deletion of a snapshot only if the snapshot is tagged with User:username for the customer.

{
   "Version":"2012-10-17",
   "Statement":[
      {
         "Effect":"Allow",
         "Action":"ec2:DeleteSnapshot",
         "Resource":"arn:aws:ec2:us-east-1::snapshot/*",
         "Condition":{
            "StringEquals":{
               "ec2:ResourceTag/User":"${aws:username}"
            }
         }
      }
   ]
}

Best Practices for Running Apache Kafka on AWS

Post Syndicated from Prasad Alle original https://aws.amazon.com/blogs/big-data/best-practices-for-running-apache-kafka-on-aws/

This post was written in partnership with Intuit to share learnings, best practices, and recommendations for running an Apache Kafka cluster on AWS. Thanks to Vaishak Suresh and his colleagues at Intuit for their contribution and support.

Intuit, in their own words: Intuit, a leading enterprise customer for AWS, is a creator of business and financial management solutions. For more information on how Intuit partners with AWS, see our previous blog post, Real-time Stream Processing Using Apache Spark Streaming and Apache Kafka on AWS. Apache Kafka is an open-source, distributed streaming platform that enables you to build real-time streaming applications.

The best practices described in this post are based on our experience in running and operating large-scale Kafka clusters on AWS for more than two years. Our intent for this post is to help AWS customers who are currently running Kafka on AWS, and also customers who are considering migrating on-premises Kafka deployments to AWS.

AWS offers Amazon Kinesis Data Streams, a Kafka alternative that is fully managed.

Running your Kafka deployment on Amazon EC2 provides a high performance, scalable solution for ingesting streaming data. AWS offers many different instance types and storage option combinations for Kafka deployments. However, given the number of possible deployment topologies, it’s not always trivial to select the most appropriate strategy suitable for your use case.

In this blog post, we cover the following aspects of running Kafka clusters on AWS:

  • Deployment considerations and patterns
  • Storage options
  • Instance types
  • Networking
  • Upgrades
  • Performance tuning
  • Monitoring
  • Security
  • Backup and restore

Note: While implementing Kafka clusters in a production environment, make sure also to consider factors like your number of messages, message size, monitoring, failure handling, and any operational issues.

Deployment considerations and patterns

In this section, we discuss various deployment options available for Kafka on AWS, along with pros and cons of each option. A successful deployment starts with thoughtful consideration of these options. Considering availability, consistency, and operational overhead of the deployment helps when choosing the right option.

Single AWS Region, Three Availability Zones, All Active

One typical deployment pattern (all active) is in a single AWS Region with three Availability Zones (AZs). One Kafka cluster is deployed in each AZ along with Apache ZooKeeper and Kafka producer and consumer instances as shown in the illustration following.

In this pattern, this is the Kafka cluster deployment:

  • Kafka producers and Kafka cluster are deployed on each AZ.
  • Data is distributed evenly across three Kafka clusters by using Elastic Load Balancer.
  • Kafka consumers aggregate data from all three Kafka clusters.

Kafka cluster failover occurs this way:

  • Mark down all Kafka producers
  • Stop consumers
  • Debug and restack Kafka
  • Restart consumers
  • Restart Kafka producers

Following are the pros and cons of this pattern.

Pros Cons
  • Highly available
  • Can sustain the failure of two AZs
  • No message loss during failover
  • Simple deployment

 

  • Very high operational overhead:
    • All changes need to be deployed three times, one for each Kafka cluster
    • Maintaining and monitoring three Kafka clusters
    • Maintaining and monitoring three consumer clusters

A restart is required for patching and upgrading brokers in a Kafka cluster. In this approach, a rolling upgrade is done separately for each cluster.

Single Region, Three Availability Zones, Active-Standby

Another typical deployment pattern (active-standby) is in a single AWS Region with a single Kafka cluster and Kafka brokers and Zookeepers distributed across three AZs. Another similar Kafka cluster acts as a standby as shown in the illustration following. You can use Kafka mirroring with MirrorMaker to replicate messages between any two clusters.

In this pattern, this is the Kafka cluster deployment:

  • Kafka producers are deployed on all three AZs.
  • Only one Kafka cluster is deployed across three AZs (active).
  • ZooKeeper instances are deployed on each AZ.
  • Brokers are spread evenly across all three AZs.
  • Kafka consumers can be deployed across all three AZs.
  • Standby Kafka producers and a Multi-AZ Kafka cluster are part of the deployment.

Kafka cluster failover occurs this way:

  • Switch traffic to standby Kafka producers cluster and Kafka cluster.
  • Restart consumers to consume from standby Kafka cluster.

Following are the pros and cons of this pattern.

Pros Cons
  • Less operational overhead when compared to the first option
  • Only one Kafka cluster to manage and consume data from
  • Can handle single AZ failures without activating a standby Kafka cluster
  • Added latency due to cross-AZ data transfer among Kafka brokers
  • For Kafka versions before 0.10, replicas for topic partitions have to be assigned so they’re distributed to the brokers on different AZs (rack-awareness)
  • The cluster can become unavailable in case of a network glitch, where ZooKeeper does not see Kafka brokers
  • Possibility of in-transit message loss during failover

Intuit recommends using a single Kafka cluster in one AWS Region, with brokers distributing across three AZs (single region, three AZs). This approach offers stronger fault tolerance than otherwise, because a failed AZ won’t cause Kafka downtime.

Storage options

There are two storage options for file storage in Amazon EC2:

Ephemeral storage is local to the Amazon EC2 instance. It can provide high IOPS based on the instance type. On the other hand, Amazon EBS volumes offer higher resiliency and you can configure IOPS based on your storage needs. EBS volumes also offer some distinct advantages in terms of recovery time. Your choice of storage is closely related to the type of workload supported by your Kafka cluster.

Kafka provides built-in fault tolerance by replicating data partitions across a configurable number of instances. If a broker fails, you can recover it by fetching all the data from other brokers in the cluster that host the other replicas. Depending on the size of the data transfer, it can affect recovery process and network traffic. These in turn eventually affect the cluster’s performance.

The following table contrasts the benefits of using an instance store versus using EBS for storage.

Instance store EBS
  • Instance storage is recommended for large- and medium-sized Kafka clusters. For a large cluster, read/write traffic is distributed across a high number of brokers, so the loss of a broker has less of an impact. However, for smaller clusters, a quick recovery for the failed node is important, but a failed broker takes longer and requires more network traffic for a smaller Kafka cluster.
  • Storage-optimized instances like h1, i3, and d2 are an ideal choice for distributed applications like Kafka.

 

  • The primary advantage of using EBS in a Kafka deployment is that it significantly reduces data-transfer traffic when a broker fails or must be replaced. The replacement broker joins the cluster much faster.
  • Data stored on EBS is persisted in case of an instance failure or termination. The broker’s data stored on an EBS volume remains intact, and you can mount the EBS volume to a new EC2 instance. Most of the replicated data for the replacement broker is already available in the EBS volume and need not be copied over the network from another broker. Only the changes made after the original broker failure need to be transferred across the network. That makes this process much faster.

 

 

Intuit chose EBS because of their frequent instance restacking requirements and also other benefits provided by EBS.

Generally, Kafka deployments use a replication factor of three. EBS offers replication within their service, so Intuit chose a replication factor of two instead of three.

Instance types

The choice of instance types is generally driven by the type of storage required for your streaming applications on a Kafka cluster. If your application requires ephemeral storage, h1, i3, and d2 instances are your best option.

Intuit used r3.xlarge instances for their brokers and r3.large for ZooKeeper, with ST1 (throughput optimized HDD) EBS for their Kafka cluster.

Here are sample benchmark numbers from Intuit tests.

Configuration Broker bytes (MB/s)
  • r3.xlarge
  • ST1 EBS
  • 12 brokers
  • 12 partitions

 

Aggregate 346.9

If you need EBS storage, then AWS has a newer-generation r4 instance. The r4 instance is superior to R3 in many ways:

  • It has a faster processor (Broadwell).
  • EBS is optimized by default.
  • It features networking based on Elastic Network Adapter (ENA), with up to 10 Gbps on smaller sizes.
  • It costs 20 percent less than R3.

Note: It’s always best practice to check for the latest changes in instance types.

Networking

The network plays a very important role in a distributed system like Kafka. A fast and reliable network ensures that nodes can communicate with each other easily. The available network throughput controls the maximum amount of traffic that Kafka can handle. Network throughput, combined with disk storage, is often the governing factor for cluster sizing.

If you expect your cluster to receive high read/write traffic, select an instance type that offers 10-Gb/s performance.

In addition, choose an option that keeps interbroker network traffic on the private subnet, because this approach allows clients to connect to the brokers. Communication between brokers and clients uses the same network interface and port. For more details, see the documentation about IP addressing for EC2 instances.

If you are deploying in more than one AWS Region, you can connect the two VPCs in the two AWS Regions using cross-region VPC peering. However, be aware of the networking costs associated with cross-AZ deployments.

Upgrades

Kafka has a history of not being backward compatible, but its support of backward compatibility is getting better. During a Kafka upgrade, you should keep your producer and consumer clients on a version equal to or lower than the version you are upgrading from. After the upgrade is finished, you can start using a new protocol version and any new features it supports. There are three upgrade approaches available, discussed following.

Rolling or in-place upgrade

In a rolling or in-place upgrade scenario, upgrade one Kafka broker at a time. Take into consideration the recommendations for doing rolling restarts to avoid downtime for end users.

Downtime upgrade

If you can afford the downtime, you can take your entire cluster down, upgrade each Kafka broker, and then restart the cluster.

Blue/green upgrade

Intuit followed the blue/green deployment model for their workloads, as described following.

If you can afford to create a separate Kafka cluster and upgrade it, we highly recommend the blue/green upgrade scenario. In this scenario, we recommend that you keep your clusters up-to-date with the latest Kafka version. For additional details on Kafka version upgrades or more details, see the Kafka upgrade documentation.

The following illustration shows a blue/green upgrade.

In this scenario, the upgrade plan works like this:

  • Create a new Kafka cluster on AWS.
  • Create a new Kafka producers stack to point to the new Kafka cluster.
  • Create topics on the new Kafka cluster.
  • Test the green deployment end to end (sanity check).
  • Using Amazon Route 53, change the new Kafka producers stack on AWS to point to the new green Kafka environment that you have created.

The roll-back plan works like this:

  • Switch Amazon Route 53 to the old Kafka producers stack on AWS to point to the old Kafka environment.

For additional details on blue/green deployment architecture using Kafka, see the re:Invent presentation Leveraging the Cloud with a Blue-Green Deployment Architecture.

Performance tuning

You can tune Kafka performance in multiple dimensions. Following are some best practices for performance tuning.

 These are some general performance tuning techniques:

  • If throughput is less than network capacity, try the following:
    • Add more threads
    • Increase batch size
    • Add more producer instances
    • Add more partitions
  • To improve latency when acks =-1, increase your num.replica.fetches value.
  • For cross-AZ data transfer, tune your buffer settings for sockets and for OS TCP.
  • Make sure that num.io.threads is greater than the number of disks dedicated for Kafka.
  • Adjust num.network.threads based on the number of producers plus the number of consumers plus the replication factor.
  • Your message size affects your network bandwidth. To get higher performance from a Kafka cluster, select an instance type that offers 10 Gb/s performance.

For Java and JVM tuning, try the following:

  • Minimize GC pauses by using the Oracle JDK, which uses the new G1 garbage-first collector.
  • Try to keep the Kafka heap size below 4 GB.

Monitoring

Knowing whether a Kafka cluster is working correctly in a production environment is critical. Sometimes, just knowing that the cluster is up is enough, but Kafka applications have many moving parts to monitor. In fact, it can easily become confusing to understand what’s important to watch and what you can set aside. Items to monitor range from simple metrics about the overall rate of traffic, to producers, consumers, brokers, controller, ZooKeeper, topics, partitions, messages, and so on.

For monitoring, Intuit used several tools, including Newrelec, Wavefront, Amazon CloudWatch, and AWS CloudTrail. Our recommended monitoring approach follows.

For system metrics, we recommend that you monitor:

  • CPU load
  • Network metrics
  • File handle usage
  • Disk space
  • Disk I/O performance
  • Garbage collection
  • ZooKeeper

For producers, we recommend that you monitor:

  • Batch-size-avg
  • Compression-rate-avg
  • Waiting-threads
  • Buffer-available-bytes
  • Record-queue-time-max
  • Record-send-rate
  • Records-per-request-avg

For consumers, we recommend that you monitor:

  • Batch-size-avg
  • Compression-rate-avg
  • Waiting-threads
  • Buffer-available-bytes
  • Record-queue-time-max
  • Record-send-rate
  • Records-per-request-avg

Security

Like most distributed systems, Kafka provides the mechanisms to transfer data with relatively high security across the components involved. Depending on your setup, security might involve different services such as encryption, Kerberos, Transport Layer Security (TLS) certificates, and advanced access control list (ACL) setup in brokers and ZooKeeper. The following tells you more about the Intuit approach. For details on Kafka security not covered in this section, see the Kafka documentation.

Encryption at rest

For EBS-backed EC2 instances, you can enable encryption at rest by using Amazon EBS volumes with encryption enabled. Amazon EBS uses AWS Key Management Service (AWS KMS) for encryption. For more details, see Amazon EBS Encryption in the EBS documentation. For instance store–backed EC2 instances, you can enable encryption at rest by using Amazon EC2 instance store encryption.

Encryption in transit

Kafka uses TLS for client and internode communications.

Authentication

Authentication of connections to brokers from clients (producers and consumers) to other brokers and tools uses either Secure Sockets Layer (SSL) or Simple Authentication and Security Layer (SASL).

Kafka supports Kerberos authentication. If you already have a Kerberos server, you can add Kafka to your current configuration.

Authorization

In Kafka, authorization is pluggable and integration with external authorization services is supported.

Backup and restore

The type of storage used in your deployment dictates your backup and restore strategy.

The best way to back up a Kafka cluster based on instance storage is to set up a second cluster and replicate messages using MirrorMaker. Kafka’s mirroring feature makes it possible to maintain a replica of an existing Kafka cluster. Depending on your setup and requirements, your backup cluster might be in the same AWS Region as your main cluster or in a different one.

For EBS-based deployments, you can enable automatic snapshots of EBS volumes to back up volumes. You can easily create new EBS volumes from these snapshots to restore. We recommend storing backup files in Amazon S3.

For more information on how to back up in Kafka, see the Kafka documentation.

Conclusion

In this post, we discussed several patterns for running Kafka in the AWS Cloud. AWS also provides an alternative managed solution with Amazon Kinesis Data Streams, there are no servers to manage or scaling cliffs to worry about, you can scale the size of your streaming pipeline in seconds without downtime, data replication across availability zones is automatic, you benefit from security out of the box, Kinesis Data Streams is tightly integrated with a wide variety of AWS services like Lambda, Redshift, Elasticsearch and it supports open source frameworks like Storm, Spark, Flink, and more. You may refer to kafka-kinesis connector.

Best Practices for Running Apache Cassandra on Amazon EC2

Post Syndicated from Prasad Alle original https://aws.amazon.com/blogs/big-data/best-practices-for-running-apache-cassandra-on-amazon-ec2/

Apache Cassandra is a commonly used, high performance NoSQL database. AWS customers that currently maintain Cassandra on-premises may want to take advantage of the scalability, reliability, security, and economic benefits of running Cassandra on Amazon EC2.

Amazon EC2 and Amazon Elastic Block Store (Amazon EBS) provide secure, resizable compute capacity and storage in the AWS Cloud. When combined, you can deploy Cassandra, allowing you to scale capacity according to your requirements. Given the number of possible deployment topologies, it’s not always trivial to select the most appropriate strategy suitable for your use case.

In this post, we outline three Cassandra deployment options, as well as provide guidance about determining the best practices for your use case in the following areas:

  • Cassandra resource overview
  • Deployment considerations
  • Storage options
  • Networking
  • High availability and resiliency
  • Maintenance
  • Security

Before we jump into best practices for running Cassandra on AWS, we should mention that we have many customers who decided to use DynamoDB instead of managing their own Cassandra cluster. DynamoDB is fully managed, serverless, and provides multi-master cross-region replication, encryption at rest, and managed backup and restore. Integration with AWS Identity and Access Management (IAM) enables DynamoDB customers to implement fine-grained access control for their data security needs.

Several customers who have been using large Cassandra clusters for many years have moved to DynamoDB to eliminate the complications of administering Cassandra clusters and maintaining high availability and durability themselves. Gumgum.com is one customer who migrated to DynamoDB and observed significant savings. For more information, see Moving to Amazon DynamoDB from Hosted Cassandra: A Leap Towards 60% Cost Saving per Year.

AWS provides options, so you’re covered whether you want to run your own NoSQL Cassandra database, or move to a fully managed, serverless DynamoDB database.

Cassandra resource overview

Here’s a short introduction to standard Cassandra resources and how they are implemented with AWS infrastructure. If you’re already familiar with Cassandra or AWS deployments, this can serve as a refresher.

Resource Cassandra AWS
Cluster

A single Cassandra deployment.

 

This typically consists of multiple physical locations, keyspaces, and physical servers.

A logical deployment construct in AWS that maps to an AWS CloudFormation StackSet, which consists of one or many CloudFormation stacks to deploy Cassandra.
Datacenter A group of nodes configured as a single replication group.

A logical deployment construct in AWS.

 

A datacenter is deployed with a single CloudFormation stack consisting of Amazon EC2 instances, networking, storage, and security resources.

Rack

A collection of servers.

 

A datacenter consists of at least one rack. Cassandra tries to place the replicas on different racks.

A single Availability Zone.
Server/node A physical virtual machine running Cassandra software. An EC2 instance.
Token Conceptually, the data managed by a cluster is represented as a ring. The ring is then divided into ranges equal to the number of nodes. Each node being responsible for one or more ranges of the data. Each node gets assigned with a token, which is essentially a random number from the range. The token value determines the node’s position in the ring and its range of data. Managed within Cassandra.
Virtual node (vnode) Responsible for storing a range of data. Each vnode receives one token in the ring. A cluster (by default) consists of 256 tokens, which are uniformly distributed across all servers in the Cassandra datacenter. Managed within Cassandra.
Replication factor The total number of replicas across the cluster. Managed within Cassandra.

Deployment considerations

One of the many benefits of deploying Cassandra on Amazon EC2 is that you can automate many deployment tasks. In addition, AWS includes services, such as CloudFormation, that allow you to describe and provision all your infrastructure resources in your cloud environment.

We recommend orchestrating each Cassandra ring with one CloudFormation template. If you are deploying in multiple AWS Regions, you can use a CloudFormation StackSet to manage those stacks. All the maintenance actions (scaling, upgrading, and backing up) should be scripted with an AWS SDK. These may live as standalone AWS Lambda functions that can be invoked on demand during maintenance.

You can get started by following the Cassandra Quick Start deployment guide. Keep in mind that this guide does not address the requirements to operate a production deployment and should be used only for learning more about Cassandra.

Deployment patterns

In this section, we discuss various deployment options available for Cassandra in Amazon EC2. A successful deployment starts with thoughtful consideration of these options. Consider the amount of data, network environment, throughput, and availability.

  • Single AWS Region, 3 Availability Zones
  • Active-active, multi-Region
  • Active-standby, multi-Region

Single region, 3 Availability Zones

In this pattern, you deploy the Cassandra cluster in one AWS Region and three Availability Zones. There is only one ring in the cluster. By using EC2 instances in three zones, you ensure that the replicas are distributed uniformly in all zones.

To ensure the even distribution of data across all Availability Zones, we recommend that you distribute the EC2 instances evenly in all three Availability Zones. The number of EC2 instances in the cluster is a multiple of three (the replication factor).

This pattern is suitable in situations where the application is deployed in one Region or where deployments in different Regions should be constrained to the same Region because of data privacy or other legal requirements.

Pros Cons

●     Highly available, can sustain failure of one Availability Zone.

●     Simple deployment

●     Does not protect in a situation when many of the resources in a Region are experiencing intermittent failure.

 

Active-active, multi-Region

In this pattern, you deploy two rings in two different Regions and link them. The VPCs in the two Regions are peered so that data can be replicated between two rings.

We recommend that the two rings in the two Regions be identical in nature, having the same number of nodes, instance types, and storage configuration.

This pattern is most suitable when the applications using the Cassandra cluster are deployed in more than one Region.

Pros Cons

●     No data loss during failover.

●     Highly available, can sustain when many of the resources in a Region are experiencing intermittent failures.

●     Read/write traffic can be localized to the closest Region for the user for lower latency and higher performance.

●     High operational overhead

●     The second Region effectively doubles the cost

 

Active-standby, multi-region

In this pattern, you deploy two rings in two different Regions and link them. The VPCs in the two Regions are peered so that data can be replicated between two rings.

However, the second Region does not receive traffic from the applications. It only functions as a secondary location for disaster recovery reasons. If the primary Region is not available, the second Region receives traffic.

We recommend that the two rings in the two Regions be identical in nature, having the same number of nodes, instance types, and storage configuration.

This pattern is most suitable when the applications using the Cassandra cluster require low recovery point objective (RPO) and recovery time objective (RTO).

Pros Cons

●     No data loss during failover.

●     Highly available, can sustain failure or partitioning of one whole Region.

●     High operational overhead.

●     High latency for writes for eventual consistency.

●     The second Region effectively doubles the cost.

Storage options

In on-premises deployments, Cassandra deployments use local disks to store data. There are two storage options for EC2 instances:

Your choice of storage is closely related to the type of workload supported by the Cassandra cluster. Instance store works best for most general purpose Cassandra deployments. However, in certain read-heavy clusters, Amazon EBS is a better choice.

The choice of instance type is generally driven by the type of storage:

  • If ephemeral storage is required for your application, a storage-optimized (I3) instance is the best option.
  • If your workload requires Amazon EBS, it is best to go with compute-optimized (C5) instances.
  • Burstable instance types (T2) don’t offer good performance for Cassandra deployments.

Instance store

Ephemeral storage is local to the EC2 instance. It may provide high input/output operations per second (IOPs) based on the instance type. An SSD-based instance store can support up to 3.3M IOPS in I3 instances. This high performance makes it an ideal choice for transactional or write-intensive applications such as Cassandra.

In general, instance storage is recommended for transactional, large, and medium-size Cassandra clusters. For a large cluster, read/write traffic is distributed across a higher number of nodes, so the loss of one node has less of an impact. However, for smaller clusters, a quick recovery for the failed node is important.

As an example, for a cluster with 100 nodes, the loss of 1 node is 3.33% loss (with a replication factor of 3). Similarly, for a cluster with 10 nodes, the loss of 1 node is 33% less capacity (with a replication factor of 3).

  Ephemeral storage Amazon EBS Comments

IOPS

(translates to higher query performance)

Up to 3.3M on I3

80K/instance

10K/gp2/volume

32K/io1/volume

This results in a higher query performance on each host. However, Cassandra implicitly scales well in terms of horizontal scale. In general, we recommend scaling horizontally first. Then, scale vertically to mitigate specific issues.

 

Note: 3.3M IOPS is observed with 100% random read with a 4-KB block size on Amazon Linux.

AWS instance types I3 Compute optimized, C5 Being able to choose between different instance types is an advantage in terms of CPU, memory, etc., for horizontal and vertical scaling.
Backup/ recovery Custom Basic building blocks are available from AWS.

Amazon EBS offers distinct advantage here. It is small engineering effort to establish a backup/restore strategy.

a) In case of an instance failure, the EBS volumes from the failing instance are attached to a new instance.

b) In case of an EBS volume failure, the data is restored by creating a new EBS volume from last snapshot.

Amazon EBS

EBS volumes offer higher resiliency, and IOPs can be configured based on your storage needs. EBS volumes also offer some distinct advantages in terms of recovery time. EBS volumes can support up to 32K IOPS per volume and up to 80K IOPS per instance in RAID configuration. They have an annualized failure rate (AFR) of 0.1–0.2%, which makes EBS volumes 20 times more reliable than typical commodity disk drives.

The primary advantage of using Amazon EBS in a Cassandra deployment is that it reduces data-transfer traffic significantly when a node fails or must be replaced. The replacement node joins the cluster much faster. However, Amazon EBS could be more expensive, depending on your data storage needs.

Cassandra has built-in fault tolerance by replicating data to partitions across a configurable number of nodes. It can not only withstand node failures but if a node fails, it can also recover by copying data from other replicas into a new node. Depending on your application, this could mean copying tens of gigabytes of data. This adds additional delay to the recovery process, increases network traffic, and could possibly impact the performance of the Cassandra cluster during recovery.

Data stored on Amazon EBS is persisted in case of an instance failure or termination. The node’s data stored on an EBS volume remains intact and the EBS volume can be mounted to a new EC2 instance. Most of the replicated data for the replacement node is already available in the EBS volume and won’t need to be copied over the network from another node. Only the changes made after the original node failed need to be transferred across the network. That makes this process much faster.

EBS volumes are snapshotted periodically. So, if a volume fails, a new volume can be created from the last known good snapshot and be attached to a new instance. This is faster than creating a new volume and coping all the data to it.

Most Cassandra deployments use a replication factor of three. However, Amazon EBS does its own replication under the covers for fault tolerance. In practice, EBS volumes are about 20 times more reliable than typical disk drives. So, it is possible to go with a replication factor of two. This not only saves cost, but also enables deployments in a region that has two Availability Zones.

EBS volumes are recommended in case of read-heavy, small clusters (fewer nodes) that require storage of a large amount of data. Keep in mind that the Amazon EBS provisioned IOPS could get expensive. General purpose EBS volumes work best when sized for required performance.

Networking

If your cluster is expected to receive high read/write traffic, select an instance type that offers 10–Gb/s performance. As an example, i3.8xlarge and c5.9xlarge both offer 10–Gb/s networking performance. A smaller instance type in the same family leads to a relatively lower networking throughput.

Cassandra generates a universal unique identifier (UUID) for each node based on IP address for the instance. This UUID is used for distributing vnodes on the ring.

In the case of an AWS deployment, IP addresses are assigned automatically to the instance when an EC2 instance is created. With the new IP address, the data distribution changes and the whole ring has to be rebalanced. This is not desirable.

To preserve the assigned IP address, use a secondary elastic network interface with a fixed IP address. Before swapping an EC2 instance with a new one, detach the secondary network interface from the old instance and attach it to the new one. This way, the UUID remains same and there is no change in the way that data is distributed in the cluster.

If you are deploying in more than one region, you can connect the two VPCs in two regions using cross-region VPC peering.

High availability and resiliency

Cassandra is designed to be fault-tolerant and highly available during multiple node failures. In the patterns described earlier in this post, you deploy Cassandra to three Availability Zones with a replication factor of three. Even though it limits the AWS Region choices to the Regions with three or more Availability Zones, it offers protection for the cases of one-zone failure and network partitioning within a single Region. The multi-Region deployments described earlier in this post protect when many of the resources in a Region are experiencing intermittent failure.

Resiliency is ensured through infrastructure automation. The deployment patterns all require a quick replacement of the failing nodes. In the case of a regionwide failure, when you deploy with the multi-Region option, traffic can be directed to the other active Region while the infrastructure is recovering in the failing Region. In the case of unforeseen data corruption, the standby cluster can be restored with point-in-time backups stored in Amazon S3.

Maintenance

In this section, we look at ways to ensure that your Cassandra cluster is healthy:

  • Scaling
  • Upgrades
  • Backup and restore

Scaling

Cassandra is horizontally scaled by adding more instances to the ring. We recommend doubling the number of nodes in a cluster to scale up in one scale operation. This leaves the data homogeneously distributed across Availability Zones. Similarly, when scaling down, it’s best to halve the number of instances to keep the data homogeneously distributed.

Cassandra is vertically scaled by increasing the compute power of each node. Larger instance types have proportionally bigger memory. Use deployment automation to swap instances for bigger instances without downtime or data loss.

Upgrades

All three types of upgrades (Cassandra, operating system patching, and instance type changes) follow the same rolling upgrade pattern.

In this process, you start with a new EC2 instance and install software and patches on it. Thereafter, remove one node from the ring. For more information, see Cassandra cluster Rolling upgrade. Then, you detach the secondary network interface from one of the EC2 instances in the ring and attach it to the new EC2 instance. Restart the Cassandra service and wait for it to sync. Repeat this process for all nodes in the cluster.

Backup and restore

Your backup and restore strategy is dependent on the type of storage used in the deployment. Cassandra supports snapshots and incremental backups. When using instance store, a file-based backup tool works best. Customers use rsync or other third-party products to copy data backups from the instance to long-term storage. For more information, see Backing up and restoring data in the DataStax documentation. This process has to be repeated for all instances in the cluster for a complete backup. These backup files are copied back to new instances to restore. We recommend using S3 to durably store backup files for long-term storage.

For Amazon EBS based deployments, you can enable automated snapshots of EBS volumes to back up volumes. New EBS volumes can be easily created from these snapshots for restoration.

Security

We recommend that you think about security in all aspects of deployment. The first step is to ensure that the data is encrypted at rest and in transit. The second step is to restrict access to unauthorized users. For more information about security, see the Cassandra documentation.

Encryption at rest

Encryption at rest can be achieved by using EBS volumes with encryption enabled. Amazon EBS uses AWS KMS for encryption. For more information, see Amazon EBS Encryption.

Instance store–based deployments require using an encrypted file system or an AWS partner solution. If you are using DataStax Enterprise, it supports transparent data encryption.

Encryption in transit

Cassandra uses Transport Layer Security (TLS) for client and internode communications.

Authentication

The security mechanism is pluggable, which means that you can easily swap out one authentication method for another. You can also provide your own method of authenticating to Cassandra, such as a Kerberos ticket, or if you want to store passwords in a different location, such as an LDAP directory.

Authorization

The authorizer that’s plugged in by default is org.apache.cassandra.auth.Allow AllAuthorizer. Cassandra also provides a role-based access control (RBAC) capability, which allows you to create roles and assign permissions to these roles.

Conclusion

In this post, we discussed several patterns for running Cassandra in the AWS Cloud. This post describes how you can manage Cassandra databases running on Amazon EC2. AWS also provides managed offerings for a number of databases. To learn more, see Purpose-built databases for all your application needs.

Operating Partner
To comply with China’s legal and regulatory requirements, AWS has formed a strategic technology collaboration with NWCD to operate and provide services from the AWS China (Ningxia) Region. Founded in 2015, NWCD is a licensed datacenter and cloud services provider, based in Ningxia, China. NWCD joins Sinnet, the operator of the AWS China China (Beijing) Region, as an AWS operating partner in China. Through these relationships, AWS provides its industry-leading technology, guidance, and expertise to NWCD and Sinnet, while NWCD and Sinnet operate and provide AWS cloud services to local customers. While the cloud services offered in both AWS China Regions are the same as those available in other AWS Regions, the AWS China Regions are different in that they are isolated from all other AWS Regions and operated by AWS’s Chinese partners separately from all other AWS Regions. Customers using the AWS China Regions enter into customer agreements with Sinnet and NWCD, rather than with AWS.

Use it Today
The AWS China (Ningxia) Region, operated by NWCD, is open for business, and you can start using it now! Starting today, Chinese developers, startups, and enterprises, as well as government, education, and non-profit organizations, can leverage AWS to run their applications and store their data in the new AWS China (Ningxia) Region, operated by NWCD. Customers already using the AWS China (Beijing) Region, operated by Sinnet, can select the AWS China (Ningxia) Region directly from the AWS Management Console, while new customers can request an account at www.amazonaws.cn to begin using both AWS China Regions.

How to Patch, Inspect, and Protect Microsoft Windows Workloads on AWS—Part 2

Post Syndicated from Koen van Blijderveen original https://aws.amazon.com/blogs/security/how-to-patch-inspect-and-protect-microsoft-windows-workloads-on-aws-part-2/

Yesterday in Part 1 of this blog post, I showed you how to:

  1. Launch an Amazon EC2 instance with an AWS Identity and Access Management (IAM) role, an Amazon Elastic Block Store (Amazon EBS) volume, and tags that Amazon EC2 Systems Manager (Systems Manager) and Amazon Inspector use.
  2. Configure Systems Manager to install the Amazon Inspector agent and patch your EC2 instances.

Today in Steps 3 and 4, I show you how to:

  1. Take Amazon EBS snapshots using Amazon EBS Snapshot Scheduler to automate snapshots based on instance tags.
  2. Use Amazon Inspector to check if your EC2 instances running Microsoft Windows contain any common vulnerabilities and exposures (CVEs).

To catch up on Steps 1 and 2, see yesterday’s blog post.

Step 3: Take EBS snapshots using EBS Snapshot Scheduler

In this section, I show you how to use EBS Snapshot Scheduler to take snapshots of your instances at specific intervals. To do this, I will show you how to:

  • Determine the schedule for EBS Snapshot Scheduler by providing you with best practices.
  • Deploy EBS Snapshot Scheduler by using AWS CloudFormation.
  • Tag your EC2 instances so that EBS Snapshot Scheduler backs up your instances when you want them backed up.

In addition to making sure your EC2 instances have all the available operating system patches applied on a regular schedule, you should take snapshots of the EBS storage volumes attached to your EC2 instances. Taking regular snapshots allows you to restore your data to a previous state quickly and cost effectively. With Amazon EBS snapshots, you pay only for the actual data you store, and snapshots save only the data that has changed since the previous snapshot, which minimizes your cost. You will use EBS Snapshot Scheduler to make regular snapshots of your EC2 instance. EBS Snapshot Scheduler takes advantage of other AWS services including CloudFormation, Amazon DynamoDB, and AWS Lambda to make backing up your EBS volumes simple.

Determine the schedule

As a best practice, you should back up your data frequently during the hours when your data changes the most. This reduces the amount of data you lose if you have to restore from a snapshot. For the purposes of this blog post, the data for my instances changes the most between the business hours of 9:00 A.M. to 5:00 P.M. Pacific Time. During these hours, I will make snapshots hourly to minimize data loss.

In addition to backing up frequently, another best practice is to establish a strategy for retention. This will vary based on how you need to use the snapshots. If you have compliance requirements to be able to restore for auditing, your needs may be different than if you are able to detect data corruption within three hours and simply need to restore to something that limits data loss to five hours. EBS Snapshot Scheduler enables you to specify the retention period for your snapshots. For this post, I only need to keep snapshots for recent business days. To account for weekends, I will set my retention period to three days, which is down from the default of 15 days when deploying EBS Snapshot Scheduler.

Deploy EBS Snapshot Scheduler

In Step 1 of Part 1 of this post, I showed how to configure an EC2 for Windows Server 2012 R2 instance with an EBS volume. You will use EBS Snapshot Scheduler to take eight snapshots each weekday of your EC2 instance’s EBS volumes:

  1. Navigate to the EBS Snapshot Scheduler deployment page and choose Launch Solution. This takes you to the CloudFormation console in your account. The Specify an Amazon S3 template URL option is already selected and prefilled. Choose Next on the Select Template page.
  2. On the Specify Details page, retain all default parameters except for AutoSnapshotDeletion. Set AutoSnapshotDeletion to Yes to ensure that old snapshots are periodically deleted. The default retention period is 15 days (you will specify a shorter value on your instance in the next subsection).
  3. Choose Next twice to move to the Review step, and start deployment by choosing the I acknowledge that AWS CloudFormation might create IAM resources check box and then choosing Create.

Tag your EC2 instances

EBS Snapshot Scheduler takes a few minutes to deploy. While waiting for its deployment, you can start to tag your instance to define its schedule. EBS Snapshot Scheduler reads tag values and looks for four possible custom parameters in the following order:

  • <snapshot time> – Time in 24-hour format with no colon.
  • <retention days> – The number of days (a positive integer) to retain the snapshot before deletion, if set to automatically delete snapshots.
  • <time zone> – The time zone of the times specified in <snapshot time>.
  • <active day(s)>all, weekdays, or mon, tue, wed, thu, fri, sat, and/or sun.

Because you want hourly backups on weekdays between 9:00 A.M. and 5:00 P.M. Pacific Time, you need to configure eight tags—one for each hour of the day. You will add the eight tags shown in the following table to your EC2 instance.

Tag Value
scheduler:ebs-snapshot:0900 0900;3;utc;weekdays
scheduler:ebs-snapshot:1000 1000;3;utc;weekdays
scheduler:ebs-snapshot:1100 1100;3;utc;weekdays
scheduler:ebs-snapshot:1200 1200;3;utc;weekdays
scheduler:ebs-snapshot:1300 1300;3;utc;weekdays
scheduler:ebs-snapshot:1400 1400;3;utc;weekdays
scheduler:ebs-snapshot:1500 1500;3;utc;weekdays
scheduler:ebs-snapshot:1600 1600;3;utc;weekdays

Next, you will add these tags to your instance. If you want to tag multiple instances at once, you can use Tag Editor instead. To add the tags in the preceding table to your EC2 instance:

  1. Navigate to your EC2 instance in the EC2 console and choose Tags in the navigation pane.
  2. Choose Add/Edit Tags and then choose Create Tag to add all the tags specified in the preceding table.
  3. Confirm you have added the tags by choosing Save. After adding these tags, navigate to your EC2 instance in the EC2 console. Your EC2 instance should look similar to the following screenshot.
    Screenshot of how your EC2 instance should look in the console
  4. After waiting a couple of hours, you can see snapshots beginning to populate on the Snapshots page of the EC2 console.Screenshot of snapshots beginning to populate on the Snapshots page of the EC2 console
  5. To check if EBS Snapshot Scheduler is active, you can check the CloudWatch rule that runs the Lambda function. If the clock icon shown in the following screenshot is green, the scheduler is active. If the clock icon is gray, the rule is disabled and does not run. You can enable or disable the rule by selecting it, choosing Actions, and choosing Enable or Disable. This also allows you to temporarily disable EBS Snapshot Scheduler.Screenshot of checking to see if EBS Snapshot Scheduler is active
  1. You can also monitor when EBS Snapshot Scheduler has run by choosing the name of the CloudWatch rule as shown in the previous screenshot and choosing Show metrics for the rule.Screenshot of monitoring when EBS Snapshot Scheduler has run by choosing the name of the CloudWatch rule

If you want to restore and attach an EBS volume, see Restoring an Amazon EBS Volume from a Snapshot and Attaching an Amazon EBS Volume to an Instance.

Step 4: Use Amazon Inspector

In this section, I show you how to you use Amazon Inspector to scan your EC2 instance for common vulnerabilities and exposures (CVEs) and set up Amazon SNS notifications. To do this I will show you how to:

  • Install the Amazon Inspector agent by using EC2 Run Command.
  • Set up notifications using Amazon SNS to notify you of any findings.
  • Define an Amazon Inspector target and template to define what assessment to perform on your EC2 instance.
  • Schedule Amazon Inspector assessment runs to assess your EC2 instance on a regular interval.

Amazon Inspector can help you scan your EC2 instance using prebuilt rules packages, which are built and maintained by AWS. These prebuilt rules packages tell Amazon Inspector what to scan for on the EC2 instances you select. Amazon Inspector provides the following prebuilt packages for Microsoft Windows Server 2012 R2:

  • Common Vulnerabilities and Exposures
  • Center for Internet Security Benchmarks
  • Runtime Behavior Analysis

In this post, I’m focused on how to make sure you keep your EC2 instances patched, backed up, and inspected for common vulnerabilities and exposures (CVEs). As a result, I will focus on how to use the CVE rules package and use your instance tags to identify the instances on which to run the CVE rules. If your EC2 instance is fully patched using Systems Manager, as described earlier, you should not have any findings with the CVE rules package. Regardless, as a best practice I recommend that you use Amazon Inspector as an additional layer for identifying any unexpected failures. This involves using Amazon CloudWatch to set up weekly Amazon Inspector scans, and configuring Amazon Inspector to notify you of any findings through SNS topics. By acting on the notifications you receive, you can respond quickly to any CVEs on any of your EC2 instances to help ensure that malware using known CVEs does not affect your EC2 instances. In a previous blog post, Eric Fitzgerald showed how to remediate Amazon Inspector security findings automatically.

Install the Amazon Inspector agent

To install the Amazon Inspector agent, you will use EC2 Run Command, which allows you to run any command on any of your EC2 instances that have the Systems Manager agent with an attached IAM role that allows access to Systems Manager.

  1. Choose Run Command under Systems Manager Services in the navigation pane of the EC2 console. Then choose Run a command.
    Screenshot of choosing "Run a command"
  2. To install the Amazon Inspector agent, you will use an AWS managed and provided command document that downloads and installs the agent for you on the selected EC2 instance. Choose AmazonInspector-ManageAWSAgent. To choose the target EC2 instance where this command will be run, use the tag you previously assigned to your EC2 instance, Patch Group, with a value of Windows Servers. For this example, set the concurrent installations to 1 and tell Systems Manager to stop after 5 errors.

  3. Retain the default values for all other settings on the Run a command page and choose Run. Back on the Run Command page, you can see if the command that installed the Amazon Inspector agent executed successfully on all selected EC2 instances.
    Screenshot showing that the command that installed the Amazon Inspector agent executed successfully on all selected EC2 instances

Set up notifications using Amazon SNS

Now that you have installed the Amazon Inspector agent, you will set up an SNS topic that will notify you of any findings after an Amazon Inspector run.

To set up an SNS topic:

  1. In the AWS Management Console, choose Simple Notification Service under Messaging in the Services menu.
  2. Choose Create topic, name your topic (only alphanumeric characters, hyphens, and underscores are allowed) and give it a display name to ensure you know what this topic does (I’ve named mine Inspector). Choose Create topic.
    "Create new topic" page
  3. To allow Amazon Inspector to publish messages to your new topic, choose Other topic actions and choose Edit topic policy.
  4. For Allow these users to publish messages to this topic and Allow these users to subscribe to this topic, choose Only these AWS users. Type the following ARN for the US East (N. Virginia) Region in which you are deploying the solution in this post: arn:aws:iam::316112463485:root. This is the ARN of Amazon Inspector itself. For the ARNs of Amazon Inspector in other AWS Regions, see Setting Up an SNS Topic for Amazon Inspector Notifications (Console). Amazon Resource Names (ARNs) uniquely identify AWS resources across all of AWS.
    Screenshot of editing the topic policy
  5. To receive notifications from Amazon Inspector, subscribe to your new topic by choosing Create subscription and adding your email address. After confirming your subscription by clicking the link in the email, the topic should display your email address as a subscriber. Later, you will configure the Amazon Inspector template to publish to this topic.
    Screenshot of subscribing to the new topic

Define an Amazon Inspector target and template

Now that you have set up the notification topic by which Amazon Inspector can notify you of findings, you can create an Amazon Inspector target and template. A target defines which EC2 instances are in scope for Amazon Inspector. A template defines which packages to run, for how long, and on which target.

To create an Amazon Inspector target:

  1. Navigate to the Amazon Inspector console and choose Get started. At the time of writing this blog post, Amazon Inspector is available in the US East (N. Virginia), US West (N. California), US West (Oregon), EU (Ireland), Asia Pacific (Mumbai), Asia Pacific (Seoul), Asia Pacific (Sydney), and Asia Pacific (Tokyo) Regions.
  2. For Amazon Inspector to be able to collect the necessary data from your EC2 instance, you must create an IAM service role for Amazon Inspector. Amazon Inspector can create this role for you if you choose Choose or create role and confirm the role creation by choosing Allow.
    Screenshot of creating an IAM service role for Amazon Inspector
  3. Amazon Inspector also asks you to tag your EC2 instance and install the Amazon Inspector agent. You already performed these steps in Part 1 of this post, so you can proceed by choosing Next. To define the Amazon Inspector target, choose the previously used Patch Group tag with a Value of Windows Servers. This is the same tag that you used to define the targets for patching. Then choose Next.
    Screenshot of defining the Amazon Inspector target
  4. Now, define your Amazon Inspector template, and choose a name and the package you want to run. For this post, use the Common Vulnerabilities and Exposures package and choose the default duration of 1 hour. As you can see, the package has a version number, so always select the latest version of the rules package if multiple versions are available.
    Screenshot of defining an assessment template
  5. Configure Amazon Inspector to publish to your SNS topic when findings are reported. You can also choose to receive a notification of a started run, a finished run, or changes in the state of a run. For this blog post, you want to receive notifications if there are any findings. To start, choose Assessment Templates from the Amazon Inspector console and choose your newly created Amazon Inspector assessment template. Choose the icon below SNS topics (see the following screenshot).
    Screenshot of choosing an assessment template
  6. A pop-up appears in which you can choose the previously created topic and the events about which you want SNS to notify you (choose Finding reported).
    Screenshot of choosing the previously created topic and the events about which you want SNS to notify you

Schedule Amazon Inspector assessment runs

The last step in using Amazon Inspector to assess for CVEs is to schedule the Amazon Inspector template to run using Amazon CloudWatch Events. This will make sure that Amazon Inspector assesses your EC2 instance on a regular basis. To do this, you need the Amazon Inspector template ARN, which you can find under Assessment templates in the Amazon Inspector console. CloudWatch Events can run your Amazon Inspector assessment at an interval you define using a Cron-based schedule. Cron is a well-known scheduling agent that is widely used on UNIX-like operating systems and uses the following syntax for CloudWatch Events.

Image of Cron schedule

All scheduled events use a UTC time zone, and the minimum precision for schedules is one minute. For more information about scheduling CloudWatch Events, see Schedule Expressions for Rules.

To create the CloudWatch Events rule:

  1. Navigate to the CloudWatch console, choose Events, and choose Create rule.
    Screenshot of starting to create a rule in the CloudWatch Events console
  2. On the next page, specify if you want to invoke your rule based on an event pattern or a schedule. For this blog post, you will select a schedule based on a Cron expression.
  3. You can schedule the Amazon Inspector assessment any time you want using the Cron expression, or you can use the Cron expression I used in the following screenshot, which will run the Amazon Inspector assessment every Sunday at 10:00 P.M. GMT.
    Screenshot of scheduling an Amazon Inspector assessment with a Cron expression
  4. Choose Add target and choose Inspector assessment template from the drop-down menu. Paste the ARN of the Amazon Inspector template you previously created in the Amazon Inspector console in the Assessment template box and choose Create a new role for this specific resource. This new role is necessary so that CloudWatch Events has the necessary permissions to start the Amazon Inspector assessment. CloudWatch Events will automatically create the new role and grant the minimum set of permissions needed to run the Amazon Inspector assessment. To proceed, choose Configure details.
    Screenshot of adding a target
  5. Next, give your rule a name and a description. I suggest using a name that describes what the rule does, as shown in the following screenshot.
  6. Finish the wizard by choosing Create rule. The rule should appear in the Events – Rules section of the CloudWatch console.
    Screenshot of completing the creation of the rule
  7. To confirm your CloudWatch Events rule works, wait for the next time your CloudWatch Events rule is scheduled to run. For testing purposes, you can choose your CloudWatch Events rule and choose Edit to change the schedule to run it sooner than scheduled.
    Screenshot of confirming the CloudWatch Events rule works
  8. Now navigate to the Amazon Inspector console to confirm the launch of your first assessment run. The Start time column shows you the time each assessment started and the Status column the status of your assessment. In the following screenshot, you can see Amazon Inspector is busy Collecting data from the selected assessment targets.
    Screenshot of confirming the launch of the first assessment run

You have concluded the last step of this blog post by setting up a regular scan of your EC2 instance with Amazon Inspector and a notification that will let you know if your EC2 instance is vulnerable to any known CVEs. In a previous Security Blog post, Eric Fitzgerald explained How to Remediate Amazon Inspector Security Findings Automatically. Although that blog post is for Linux-based EC2 instances, the post shows that you can learn about Amazon Inspector findings in other ways than email alerts.

Conclusion

In this two-part blog post, I showed how to make sure you keep your EC2 instances up to date with patching, how to back up your instances with snapshots, and how to monitor your instances for CVEs. Collectively these measures help to protect your instances against common attack vectors that attempt to exploit known vulnerabilities. In Part 1, I showed how to configure your EC2 instances to make it easy to use Systems Manager, EBS Snapshot Scheduler, and Amazon Inspector. I also showed how to use Systems Manager to schedule automatic patches to keep your instances current in a timely fashion. In Part 2, I showed you how to take regular snapshots of your data by using EBS Snapshot Scheduler and how to use Amazon Inspector to check if your EC2 instances running Microsoft Windows contain any common vulnerabilities and exposures (CVEs).

How to Patch, Inspect, and Protect Microsoft Windows Workloads on AWS—Part 1

Post Syndicated from Koen van Blijderveen original https://aws.amazon.com/blogs/security/how-to-patch-inspect-and-protect-microsoft-windows-workloads-on-aws-part-1/

Most malware tries to compromise your systems by using a known vulnerability that the maker of the operating system has already patched. To help prevent malware from affecting your systems, two security best practices are to apply all operating system patches to your systems and actively monitor your systems for missing patches. In case you do need to recover from a malware attack, you should make regular backups of your data.

In today’s blog post (Part 1 of a two-part post), I show how to keep your Amazon EC2 instances that run Microsoft Windows up to date with the latest security patches by using Amazon EC2 Systems Manager. Tomorrow in Part 2, I show how to take regular snapshots of your data by using Amazon EBS Snapshot Scheduler and how to use Amazon Inspector to check if your EC2 instances running Microsoft Windows contain any common vulnerabilities and exposures (CVEs).

What you should know first

To follow along with the solution in this post, you need one or more EC2 instances. You may use existing instances or create new instances. For the blog post, I assume this is an EC2 for Microsoft Windows Server 2012 R2 instance installed from the Amazon Machine Images (AMIs). If you are not familiar with how to launch an EC2 instance, see Launching an Instance. I also assume you launched or will launch your instance in a private subnet. A private subnet is not directly accessible via the internet, and access to it requires either a VPN connection to your on-premises network or a jump host in a public subnet (a subnet with access to the internet). You must make sure that the EC2 instance can connect to the internet using a network address translation (NAT) instance or NAT gateway to communicate with Systems Manager and Amazon Inspector. The following diagram shows how you should structure your Amazon Virtual Private Cloud (VPC). You should also be familiar with Restoring an Amazon EBS Volume from a Snapshot and Attaching an Amazon EBS Volume to an Instance.

Later on, you will assign tasks to a maintenance window to patch your instances with Systems Manager. To do this, the AWS Identity and Access Management (IAM) user you are using for this post must have the iam:PassRole permission. This permission allows this IAM user to assign tasks to pass their own IAM permissions to the AWS service. In this example, when you assign a task to a maintenance window, IAM passes your credentials to Systems Manager. This safeguard ensures that the user cannot use the creation of tasks to elevate their IAM privileges because their own IAM privileges limit which tasks they can run against an EC2 instance. You should also authorize your IAM user to use EC2, Amazon Inspector, Amazon CloudWatch, and Systems Manager. You can achieve this by attaching the following AWS managed policies to the IAM user you are using for this example: AmazonInspectorFullAccess, AmazonEC2FullAccess, and AmazonSSMFullAccess.

Architectural overview

The following diagram illustrates the components of this solution’s architecture.

Diagram showing the components of this solution's architecture

For this blog post, Microsoft Windows EC2 is Amazon EC2 for Microsoft Windows Server 2012 R2 instances with attached Amazon Elastic Block Store (Amazon EBS) volumes, which are running in your VPC. These instances may be standalone Windows instances running your Windows workloads, or you may have joined them to an Active Directory domain controller. For instances joined to a domain, you can be using Active Directory running on an EC2 for Windows instance, or you can use AWS Directory Service for Microsoft Active Directory.

Amazon EC2 Systems Manager is a scalable tool for remote management of your EC2 instances. You will use the Systems Manager Run Command to install the Amazon Inspector agent. The agent enables EC2 instances to communicate with the Amazon Inspector service and run assessments, which I explain in detail later in this blog post. You also will create a Systems Manager association to keep your EC2 instances up to date with the latest security patches.

You can use the EBS Snapshot Scheduler to schedule automated snapshots at regular intervals. You will use it to set up regular snapshots of your Amazon EBS volumes. EBS Snapshot Scheduler is a prebuilt solution by AWS that you will deploy in your AWS account. With Amazon EBS snapshots, you pay only for the actual data you store. Snapshots save only the data that has changed since the previous snapshot, which minimizes your cost.

You will use Amazon Inspector to run security assessments on your EC2 for Windows Server instance. In this post, I show how to assess if your EC2 for Windows Server instance is vulnerable to any of the more than 50,000 CVEs registered with Amazon Inspector.

In today’s and tomorrow’s posts, I show you how to:

  1. Launch an EC2 instance with an IAM role, Amazon EBS volume, and tags that Systems Manager and Amazon Inspector will use.
  2. Configure Systems Manager to install the Amazon Inspector agent and patch your EC2 instances.
  3. Take EBS snapshots by using EBS Snapshot Scheduler to automate snapshots based on instance tags.
  4. Use Amazon Inspector to check if your EC2 instances running Microsoft Windows contain any common vulnerabilities and exposures (CVEs).

Step 1: Launch an EC2 instance

In this section, I show you how to launch your EC2 instances so that you can use Systems Manager with the instances and use instance tags with EBS Snapshot Scheduler to automate snapshots. This requires three things:

  • Create an IAM role for Systems Manager before launching your EC2 instance.
  • Launch your EC2 instance with Amazon EBS and the IAM role for Systems Manager.
  • Add tags to instances so that you can automate policies for which instances you take snapshots of and when.

Create an IAM role for Systems Manager

Before launching your EC2 instance, I recommend that you first create an IAM role for Systems Manager, which you will use to update the EC2 instance you will launch. AWS already provides a preconfigured policy that you can use for your new role, and it is called AmazonEC2RoleforSSM.

  1. Sign in to the IAM console and choose Roles in the navigation pane. Choose Create new role.
    Screenshot of choosing "Create role"
  2. In the role-creation workflow, choose AWS service > EC2 > EC2 to create a role for an EC2 instance.
    Screenshot of creating a role for an EC2 instance
  3. Choose the AmazonEC2RoleforSSM policy to attach it to the new role you are creating.
    Screenshot of attaching the AmazonEC2RoleforSSM policy to the new role you are creating
  4. Give the role a meaningful name (I chose EC2SSM) and description, and choose Create role.
    Screenshot of giving the role a name and description

Launch your EC2 instance

To follow along, you need an EC2 instance that is running Microsoft Windows Server 2012 R2 and that has an Amazon EBS volume attached. You can use any existing instance you may have or create a new instance.

When launching your new EC2 instance, be sure that:

  • The operating system is Microsoft Windows Server 2012 R2.
  • You attach at least one Amazon EBS volume to the EC2 instance.
  • You attach the newly created IAM role (EC2SSM).
  • The EC2 instance can connect to the internet through a network address translation (NAT) gateway or a NAT instance.
  • You create the tags shown in the following screenshot (you will use them later).

If you are using an already launched EC2 instance, you can attach the newly created role as described in Easily Replace or Attach an IAM Role to an Existing EC2 Instance by Using the EC2 Console.

Add tags

The final step of configuring your EC2 instances is to add tags. You will use these tags to configure Systems Manager in Step 2 of this blog post and to configure Amazon Inspector in Part 2. For this example, I add a tag key, Patch Group, and set the value to Windows Servers. I could have other groups of EC2 instances that I treat differently by having the same tag key but a different tag value. For example, I might have a collection of other servers with the Patch Group tag key with a value of IAS Servers.

Screenshot of adding tags

Note: You must wait a few minutes until the EC2 instance becomes available before you can proceed to the next section.

At this point, you now have at least one EC2 instance you can use to configure Systems Manager, use EBS Snapshot Scheduler, and use Amazon Inspector.

Note: If you have a large number of EC2 instances to tag, you may want to use the EC2 CreateTags API rather than manually apply tags to each instance.

Step 2: Configure Systems Manager

In this section, I show you how to use Systems Manager to apply operating system patches to your EC2 instances, and how to manage patch compliance.

To start, I will provide some background information about Systems Manager. Then, I will cover how to:

  • Create the Systems Manager IAM role so that Systems Manager is able to perform patch operations.
  • Associate a Systems Manager patch baseline with your instance to define which patches Systems Manager should apply.
  • Define a maintenance window to make sure Systems Manager patches your instance when you tell it to.
  • Monitor patch compliance to verify the patch state of your instances.

Systems Manager is a collection of capabilities that helps you automate management tasks for AWS-hosted instances on EC2 and your on-premises servers. In this post, I use Systems Manager for two purposes: to run remote commands and apply operating system patches. To learn about the full capabilities of Systems Manager, see What Is Amazon EC2 Systems Manager?

Patch management is an important measure to prevent malware from infecting your systems. Most malware attacks look for vulnerabilities that are publicly known and in most cases are already patched by the maker of the operating system. These publicly known vulnerabilities are well documented and therefore easier for an attacker to exploit than having to discover a new vulnerability.

Patches for these new vulnerabilities are available through Systems Manager within hours after Microsoft releases them. There are two prerequisites to use Systems Manager to apply operating system patches. First, you must attach the IAM role you created in the previous section, EC2SSM, to your EC2 instance. Second, you must install the Systems Manager agent on your EC2 instance. If you have used a recent Microsoft Windows Server 2012 R2 AMI published by AWS, Amazon has already installed the Systems Manager agent on your EC2 instance. You can confirm this by logging in to an EC2 instance and looking for Amazon SSM Agent under Programs and Features in Windows. To install the Systems Manager agent on an instance that does not have the agent preinstalled or if you want to use the Systems Manager agent on your on-premises servers, see the documentation about installing the Systems Manager agent. If you forgot to attach the newly created role when launching your EC2 instance or if you want to attach the role to already running EC2 instances, see Attach an AWS IAM Role to an Existing Amazon EC2 Instance by Using the AWS CLI or use the AWS Management Console.

To make sure your EC2 instance receives operating system patches from Systems Manager, you will use the default patch baseline provided and maintained by AWS, and you will define a maintenance window so that you control when your EC2 instances should receive patches. For the maintenance window to be able to run any tasks, you also must create a new role for Systems Manager. This role is a different kind of role than the one you created earlier: Systems Manager will use this role instead of EC2. Earlier we created the EC2SSM role with the AmazonEC2RoleforSSM policy, which allowed the Systems Manager agent on our instance to communicate with the Systems Manager service. Here we need a new role with the policy AmazonSSMMaintenanceWindowRole to make sure the Systems Manager service is able to execute commands on our instance.

Create the Systems Manager IAM role

To create the new IAM role for Systems Manager, follow the same procedure as in the previous section, but in Step 3, choose the AmazonSSMMaintenanceWindowRole policy instead of the previously selected AmazonEC2RoleforSSM policy.

Screenshot of creating the new IAM role for Systems Manager

Finish the wizard and give your new role a recognizable name. For example, I named my role MaintenanceWindowRole.

Screenshot of finishing the wizard and giving your new role a recognizable name

By default, only EC2 instances can assume this new role. You must update the trust policy to enable Systems Manager to assume this role.

To update the trust policy associated with this new role:

  1. Navigate to the IAM console and choose Roles in the navigation pane.
  2. Choose MaintenanceWindowRole and choose the Trust relationships tab. Then choose Edit trust relationship.
  3. Update the policy document by copying the following policy and pasting it in the Policy Document box. As you can see, I have added the ssm.amazonaws.com service to the list of allowed Principals that can assume this role. Choose Update Trust Policy.
    {
       "Version":"2012-10-17",
       "Statement":[
          {
             "Sid":"",
             "Effect":"Allow",
             "Principal":{
                "Service":[
                   "ec2.amazonaws.com",
                   "ssm.amazonaws.com"
               ]
             },
             "Action":"sts:AssumeRole"
          }
       ]
    }

Associate a Systems Manager patch baseline with your instance

Next, you are going to associate a Systems Manager patch baseline with your EC2 instance. A patch baseline defines which patches Systems Manager should apply. You will use the default patch baseline that AWS manages and maintains. Before you can associate the patch baseline with your instance, though, you must determine if Systems Manager recognizes your EC2 instance.

Navigate to the EC2 console, scroll down to Systems Manager Shared Resources in the navigation pane, and choose Managed Instances. Your new EC2 instance should be available there. If your instance is missing from the list, verify the following:

  1. Go to the EC2 console and verify your instance is running.
  2. Select your instance and confirm you attached the Systems Manager IAM role, EC2SSM.
  3. Make sure that you deployed a NAT gateway in your public subnet to ensure your VPC reflects the diagram at the start of this post so that the Systems Manager agent can connect to the Systems Manager internet endpoint.
  4. Check the Systems Manager Agent logs for any errors.

Now that you have confirmed that Systems Manager can manage your EC2 instance, it is time to associate the AWS maintained patch baseline with your EC2 instance:

  1. Choose Patch Baselines under Systems Manager Services in the navigation pane of the EC2 console.
  2. Choose the default patch baseline as highlighted in the following screenshot, and choose Modify Patch Groups in the Actions drop-down.
    Screenshot of choosing Modify Patch Groups in the Actions drop-down
  3. In the Patch group box, enter the same value you entered under the Patch Group tag of your EC2 instance in “Step 1: Configure your EC2 instance.” In this example, the value I enter is Windows Servers. Choose the check mark icon next to the patch group and choose Close.Screenshot of modifying the patch group

Define a maintenance window

Now that you have successfully set up a role and have associated a patch baseline with your EC2 instance, you will define a maintenance window so that you can control when your EC2 instances should receive patches. By creating multiple maintenance windows and assigning them to different patch groups, you can make sure your EC2 instances do not all reboot at the same time. The Patch Group resource tag you defined earlier will determine to which patch group an instance belongs.

To define a maintenance window:

  1. Navigate to the EC2 console, scroll down to Systems Manager Shared Resources in the navigation pane, and choose Maintenance Windows. Choose Create a Maintenance Window.
    Screenshot of starting to create a maintenance window in the Systems Manager console
  2. Select the Cron schedule builder to define the schedule for the maintenance window. In the example in the following screenshot, the maintenance window will start every Saturday at 10:00 P.M. UTC.
  3. To specify when your maintenance window will end, specify the duration. In this example, the four-hour maintenance window will end on the following Sunday morning at 2:00 A.M. UTC (in other words, four hours after it started).
  4. Systems manager completes all tasks that are in process, even if the maintenance window ends. In my example, I am choosing to prevent new tasks from starting within one hour of the end of my maintenance window because I estimated my patch operations might take longer than one hour to complete. Confirm the creation of the maintenance window by choosing Create maintenance window.
    Screenshot of completing all boxes in the maintenance window creation process
  5. After creating the maintenance window, you must register the EC2 instance to the maintenance window so that Systems Manager knows which EC2 instance it should patch in this maintenance window. To do so, choose Register new targets on the Targets tab of your newly created maintenance window. You can register your targets by using the same Patch Group tag you used before to associate the EC2 instance with the AWS-provided patch baseline.
    Screenshot of registering new targets
  6. Assign a task to the maintenance window that will install the operating system patches on your EC2 instance:
    1. Open Maintenance Windows in the EC2 console, select your previously created maintenance window, choose the Tasks tab, and choose Register run command task from the Register new task drop-down.
    2. Choose the AWS-RunPatchBaseline document from the list of available documents.
    3. For Parameters:
      1. For Role, choose the role you created previously (called MaintenanceWindowRole).
      2. For Execute on, specify how many EC2 instances Systems Manager should patch at the same time. If you have a large number of EC2 instances and want to patch all EC2 instances within the defined time, make sure this number is not too low. For example, if you have 1,000 EC2 instances, a maintenance window of 4 hours, and 2 hours’ time for patching, make this number at least 500.
      3. For Stop after, specify after how many errors Systems Manager should stop.
      4. For Operation, choose Install to make sure to install the patches.
        Screenshot of stipulating maintenance window parameters

Now, you must wait for the maintenance window to run at least once according to the schedule you defined earlier. Note that if you don’t want to wait, you can adjust the schedule to run sooner by choosing Edit maintenance window on the Maintenance Windows page of Systems Manager. If your maintenance window has expired, you can check the status of any maintenance tasks Systems Manager has performed on the Maintenance Windows page of Systems Manager and select your maintenance window.

Screenshot of the maintenance window successfully created

Monitor patch compliance

You also can see the overall patch compliance of all EC2 instances that are part of defined patch groups by choosing Patch Compliance under Systems Manager Services in the navigation pane of the EC2 console. You can filter by Patch Group to see how many EC2 instances within the selected patch group are up to date, how many EC2 instances are missing updates, and how many EC2 instances are in an error state.

Screenshot of monitoring patch compliance

In this section, you have set everything up for patch management on your instance. Now you know how to patch your EC2 instance in a controlled manner and how to check if your EC2 instance is compliant with the patch baseline you have defined. Of course, I recommend that you apply these steps to all EC2 instances you manage.

Summary

In Part 1 of this blog post, I have shown how to configure EC2 instances for use with Systems Manager, EBS Snapshot Scheduler, and Amazon Inspector. I also have shown how to use Systems Manager to keep your Microsoft Windows–based EC2 instances up to date. In Part 2 of this blog post tomorrow, I will show how to take regular snapshots of your data by using EBS Snapshot Scheduler and how to use Amazon Inspector to check if your EC2 instances running Microsoft Windows contain any CVEs.

AWS Achieves FedRAMP JAB Moderate Provisional Authorization for 20 Services in the AWS US East/West Region

Post Syndicated from Chris Gile original https://aws.amazon.com/blogs/security/aws-achieves-fedramp-jab-moderate-authorization-for-20-services-in-us-eastwest/

The AWS US East/West Region has received a Provisional Authority to Operate (P-ATO) from the Joint Authorization Board (JAB) at the Federal Risk and Authorization Management Program (FedRAMP) Moderate baseline.

Though AWS has maintained an AWS US East/West Region Agency-ATO since early 2013, this announcement represents AWS’s carefully deliberated move to the JAB for the centralized maintenance of our P-ATO for 10 services already authorized. This also includes the addition of 10 new services to our FedRAMP program (see the complete list of services below). This doubles the number of FedRAMP Moderate services available to our customers to enable increased use of the cloud and support modernized IT missions. Our public sector customers now can leverage this FedRAMP P-ATO as a baseline for their own authorizations and look to the JAB for centralized Continuous Monitoring reporting and updates. In a significant enhancement for our partners that build their solutions on the AWS US East/West Region, they can now achieve FedRAMP JAB P-ATOs of their own for their Platform as a Service (PaaS) and Software as a Service (SaaS) offerings.

In line with FedRAMP security requirements, our independent FedRAMP assessment was completed in partnership with a FedRAMP accredited Third Party Assessment Organization (3PAO) on our technical, management, and operational security controls to validate that they meet or exceed FedRAMP’s Moderate baseline requirements. Effective immediately, you can begin leveraging this P-ATO for the following 20 services in the AWS US East/West Region:

  • Amazon Aurora (MySQL)*
  • Amazon CloudWatch Logs*
  • Amazon DynamoDB
  • Amazon Elastic Block Store
  • Amazon Elastic Compute Cloud
  • Amazon EMR*
  • Amazon Glacier*
  • Amazon Kinesis Streams*

Prime Day 2017 – Powered by AWS

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/prime-day-2017-powered-by-aws/

The third annual Prime Day set another round of records for global orders, topping Black Friday and Cyber Monday, making it the biggest day in Amazon retail history. Over the course of the 30 hour event, tens of millions of Prime members purchased things like Echo Dots, Fire tablets, programmable pressure cookers, espresso machines, rechargeable batteries, and much more! July 11th also set a record for the number of new Prime memberships, as people signed up in order to take advantage of hundreds of thousands of deals. Amazon customers shopped online and made heavy use of the Amazon App, with mobile orders more than doubling from last Prime Day.

Powered by AWS
Last year I told you about How AWS Powered Amazon’s Biggest Day Ever, and shared what the team had learned with regard to preparation, automation, monitoring, and thinking big. All of those lessons still apply and you can read that post to learn more. Preparation for this year’s Prime Day (which started just days after Prime Day 2016 wrapped up) started by collecting and sharing best practices and identifying areas for improvement, proceeding to implementation and stress testing as the big day approached. Two of the best practices involve auditing and GameDay:

Auditing – This is a formal way for us to track preparations, identify risks, and to track progress against our objectives. Each team must respond to a series of detailed technical and operational questions that are designed to help them determine their readiness. On the technical side, questions could revolve around time to recovery after a database failure, including the all-important check of the TTL (time to live) for the CNAME. Operational questions address schedules for on-call personnel, points of contact, and ownership of services & instances.

GameDay – This practice (which I believe originated with former Amazonian Jesse Robbins), is intended to validate all of the capacity planning & preparation and to verify that all of the necessary operational practices are in place and work as expected. It introduces simulated failures and helps to train the team to identify and quickly resolve issues, building muscle memory in the process. It also tests failover and recovery capabilities, and can expose latent defects that are lurking under the covers. GameDays help teams to understand scaling drivers (page views, orders, and so forth) and gives them an opportunity to test their scaling practices. To learn more, read Resilience Engineering: Learning to Embrace Failure or watch the video: GameDay: Creating Resiliency Through Destruction.

Prime Day 2017 Metrics
So, how did we do this year?

The AWS teams checked their dashboards and log files, and were happy to share their metrics with me. Here are a few of the most interesting ones:

Block Storage – Use of Amazon Elastic Block Store (EBS) grew by 40% year-over-year, with aggregate data transfer jumping to 52 petabytes (a 50% increase) for the day and total I/O requests rising to 835 million (a 30% increase). The team told me that they loved the elasticity of EBS, and that they were able to ramp down on capacity after Prime Day concluded instead of being stuck with it.

NoSQL Database – Amazon DynamoDB requests from Alexa, the Amazon.com sites, and the Amazon fulfillment centers totaled 3.34 trillion, peaking at 12.9 million per second. According to the team, the extreme scale, consistent performance, and high availability of DynamoDB let them meet needs of Prime Day without breaking a sweat.

Stack Creation – Nearly 31,000 AWS CloudFormation stacks were created for Prime Day in order to bring additional AWS resources on line.

API Usage – AWS CloudTrail processed over 50 billion events and tracked more than 419 billion calls to various AWS APIs, all in support of Prime Day.

Configuration TrackingAWS Config generated over 14 million Configuration items for AWS resources.

You Can Do It
Running an event that is as large, complex, and mission-critical as Prime Day takes a lot of planning. If you have an event of this type in mind, please take a look at our new Infrastructure Event Readiness white paper. Inside, you will learn how to design and provision your applications to smoothly handle planned scaling events such as product launches or seasonal traffic spikes, with sections on automation, resiliency, cost optimization, event management, and more.

AWS Hot Startups – August 2017

Post Syndicated from Tina Barr original https://aws.amazon.com/blogs/aws/aws-hot-startups-august-2017/

There’s no doubt about it – Artificial Intelligence is changing the world and how it operates. Across industries, organizations from startups to Fortune 500s are embracing AI to develop new products, services, and opportunities that are more efficient and accessible for their consumers. From driverless cars to better preventative healthcare to smart home devices, AI is driving innovation at a fast rate and will continue to play a more important role in our everyday lives.

This month we’d like to highlight startups using AI solutions to help companies grow. We are pleased to feature:

  • SignalBox – a simple and accessible deep learning platform to help businesses get started with AI.
  • Valossa – an AI video recognition platform for the media and entertainment industry.
  • Kaliber – innovative applications for businesses using facial recognition, deep learning, and big data.

SignalBox (UK)

In 2016, SignalBox founder Alain Richardt was hearing the same comments being made by developers, data scientists, and business leaders. They wanted to get into deep learning but didn’t know where to start. Alain saw an opportunity to commodify and apply deep learning by providing a platform that does the heavy lifting with an easy-to-use web interface, blueprints for common tasks, and just a single-click to productize the models. With SignalBox, companies can start building deep learning models with no coding at all – they just select a data set, choose a network architecture, and go. SignalBox also offers step-by-step tutorials, tips and tricks from industry experts, and consulting services for customers that want an end-to-end AI solution.

SignalBox offers a variety of solutions that are being used across many industries for energy modeling, fraud detection, customer segmentation, insurance risk modeling, inventory prediction, real estate prediction, and more. Existing data science teams are using SignalBox to accelerate their innovation cycle. One innovative UK startup, Energi Mine, recently worked with SignalBox to develop deep networks that predict anomalous energy consumption patterns and do time series predictions on energy usage for businesses with hundreds of sites.

SignalBox uses a variety of AWS services including Amazon EC2, Amazon VPC, Amazon Elastic Block Store, and Amazon S3. The ability to rapidly provision EC2 GPU instances has been a critical factor in their success – both in terms of keeping their operational expenses low, as well as speed to market. The Amazon API Gateway has allowed for operational automation, giving SignalBox the ability to control its infrastructure.

Valossa (Finland)

As students at the University of Oulu in Finland, the Valossa founders spent years doing research in the computer science and AI labs. During that time, the team witnessed how the world was moving beyond text, with video playing a greater role in day-to-day communication. This spawned an idea to use technology to automatically understand what an audience is viewing and share that information with a global network of content producers. Since 2015, Valossa has been building next generation AI applications to benefit the media and entertainment industry and is moving beyond the capabilities of traditional visual recognition systems.

Valossa’s AI is capable of analyzing any video stream. The AI studies a vast array of data within videos and converts that information into descriptive tags, categories, and overviews automatically. Basically, it sees, hears, and understands videos like a human does. The Valossa AI can detect people, visual and auditory concepts, key speech elements, and labels explicit content to make moderating and filtering content simpler. Valossa’s solutions are designed to provide value for the content production workflow, from media asset management to end-user applications for content discovery. AI-annotated content allows online viewers to jump directly to their favorite scenes or search specific topics and actors within a video.

Valossa leverages AWS to deliver the industry’s first complete AI video recognition platform. Using Amazon EC2 GPU instances, Valossa can easily scale their computation capacity based on customer activity. High-volume video processing with GPU instances provides the necessary speed for time-sensitive workflows. The geo-located Availability Zones in EC2 allow Valossa to bring resources close to their customers to minimize network delays. Valossa also uses Amazon S3 for video ingestion and to provide end-user video analytics, which makes managing and accessing media data easy and highly scalable.

To see how Valossa works, check out www.WhatIsMyMovie.com or enable the Alexa Skill, Valossa Movie Finder. To try the Valossa AI, sign up for free at www.valossa.com.

Kaliber (San Francisco, CA)

Serial entrepreneurs Ray Rahman and Risto Haukioja founded Kaliber in 2016. The pair had previously worked in startups building smart cities and online privacy tools, and teamed up to bring AI to the workplace and change the hospitality industry. Our world is designed to appeal to our senses – stores and warehouses have clearly marked aisles, products are colorfully packaged, and we use these designs to differentiate one thing from another. We tell each other apart by our faces, and previously that was something only humans could measure or act upon. Kaliber is using facial recognition, deep learning, and big data to create solutions for business use. Markets and companies that aren’t typically associated with cutting-edge technology will be able to use their existing camera infrastructure in a whole new way, making them more efficient and better able to serve their customers.

Computer video processing is rapidly expanding, and Kaliber believes that video recognition will extend to far more than security cameras and robots. Using the clients’ network of in-house cameras, Kaliber’s platform extracts key data points and maps them to actionable insights using their machine learning (ML) algorithm. Dashboards connect users to the client’s BI tools via the Kaliber enterprise APIs, and managers can view these analytics to improve their real-world processes, taking immediate corrective action with real-time alerts. Kaliber’s Real Metrics are aimed at combining the power of image recognition with ML to ultimately provide a more meaningful experience for all.

Kaliber uses many AWS services, including Amazon Rekognition, Amazon Kinesis, AWS Lambda, Amazon EC2 GPU instances, and Amazon S3. These services have been instrumental in helping Kaliber meet the needs of enterprise customers in record time.

New – Cost Allocation for EBS Snapshots

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/new-cost-allocation-for-ebs-snapshots/

Amazon Elastic Block Store (EBS) allows you to create persistent block storage volumes for your Amazon EC2 instances. The volumes offer consistent, low-latency performance and a choice of volume types. You can take snapshot backups of your EBS volumes, keep them for as long as you would like, and then restore them to a fresh volume.

AWS Billing and Cost Management provide you with tools and reports that you can use to track your spending. You can use Cost Allocation Tags to assign costs to your customers, applications, teams, departments, or billing codes at the level of individual resources.

Cost Allocation for Snapshots
Today we are adding cost allocation for EBS snapshots. While I expect AWS customers of all shapes and sizes to make good use of this feature, I know that enterprises will find it particularly interesting. They’ll be able to assign costs to the proper project, department, or entity. Similarly, Managed Service Providers, some of whom manage AWS footprints that encompass thousands of EBS volumes and many more EBS snapshots, will be able to map snapshot costs back to customer accounts and applications.

Tagging Snapshots and Generating Reports
Let’s walk through the process of tagging snapshots and allocating costs.

The first step is to implement a tagging regimen for your existing snapshots. You can create a script that calls the create-tags command or write code that calls the TagResources function. You can also use the Console’s Tag Editor to find the snapshots of interest across any number of AWS Regions:

I have a handful of snapshots and simply tagged some them by hand. My tag key is usage and the values are backup, dev, and metrics. Here are my snapshots:

Next, I need to tell AWS that the new tag key is being used for cost allocation. I open up the Billing Dashboard and click on Cost Allocation Tags:

Then I locate my tag in the list of user-defined tags, select it, and clicked on Activate:

AWS will deliver the first updated report within 24 hours, and will update Cost Explorer at least once per day after that (read Understanding Your Usage with Billing Reports to learn more).

I have two options. I can use Cost Explorer to explore the data visually, or I can create a usage report, download it into Excel and analyze it on my desktop. I’ll show you both!

Using Cost Explorer
I open up Cost Explorer, select the time range of interest, and filter by Usage Type Group, selecting EC2: EBS – Snapshots. Then I set the Group by option to Tag and choose my tag (usage) from the drop-down:

Then I click on Apply and inspect the report:

I can see my costs and my usage (measured in gigabyte-months) at a glance. I can also click on New report, enter a name, and save the report for reuse:

Creating a Cost & Usage Report
I click on Reports and Create Report, to create a report. I named it DailySnapshotUsage and set the Time unit to be Daily:

Then I point it at my jbarr-billing bucket, select ZIP compression, and click on Next:

I confirm my settings on the next page and click on Review and Complete to finalize my report. I check back the next day and my report is ready:

Analyzing the Cost & Usage Report Using Excel
I can also download the cost and and usage report and analyze it using Excel.

I switch to the S3 Console, open up the jbarr-billing bucket, and descend in to the folder structure to find my report:

Then I download and unzip the file, and open it in Excel:

I want to see only the tagged usage, so I scroll over to column DJ (resourceTags/user:usage) and use Excel’s Filter operation to choose the tags of interest:

Then I hide most of the columns and end up with line item costs:

I’m highly confident that your Excel skills are better than mine, and that you can do a far better job of analyzing the data!

Understanding Snapshot Costs
As you create your reports and analyze your EBS snapshot costs and usage, keep in mind that snapshots are created incrementally and that the first snapshot will generally appear to be the most expensive one. If you delete a snapshot that contains blocks that are being used by a later snapshot, the space referenced by the blocks will now be attributed to the later snapshot. Therefore, with respect to a particular EBS volume, deleting the snapshot with the highest cost may simply move some of the costs to a more recent snapshot. Read Deleting an Amazon EBS Snapshot to learn more.

Available Now
This new feature is available now in all commercial AWS regions and you can start using it today.

EC2 F1 Instances with FPGAs – Now Generally Available

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/ec2-f1-instances-with-fpgas-now-generally-available/

We launched the Developer Preview of the FPGA-equipped F1 instances at AWS re:Invent. The response to the announcement was quick and overwhelming! We received over 2000 requests for entry, and were able to provide over 200 developers with access to the Hardware Development Kit (HDK) and the actual F1 instances.

In the post that I wrote for re:Invent, I told you that:

This highly parallelized model is ideal for building custom accelerators to process compute-intensive problems. Properly programmed, an FPGA has the potential to provide a 30x speedup to many types of genomics, seismic analysis, financial risk analysis, big data search, and encryption algorithms and applications.

During the preview, partners and developers have been working on all sorts of exciting tools, services, and applications. I’ll tell you more about them in just a moment.

Now Generally Available
Today we are making the F1 instances generally available in the US East (Northern Virginia) Region, with plans to bring them to other regions before too long.

We continued to add features and functions during the preview, while also making the development tools more efficient and easier to use. Here’s a summary:

Developer Community – We launched the AWS FPGA Development Forum to provide a place for FPGA developers to hang out and to communicate with us and with each other.

HDK and SDK – We published the EC2 FPGA Hardware (HDK) and Software Development Kit to GitHub, and made many improvements in response to feedback that we received during the preview.

The improvements include support for VHDL (in addition to Verilog), an improved virtual lab environment (Virtual JTAG, Virtual LED, and Virtual DipSwitch), AWS libraries for FPGA management and the FPGA runtime, and support for OpenCL including the AWS OpenCL runtime library.

FPGA Developer AMI – This Marketplace AMI contains a full set of FPGA development tools including an RTL compiler and simulator, along with Xilinx SDAccel for OpenCL development, all tuned for use on C4, M4, and R4 instances.

FPGAs At Work
Here’s a sampling of the impressive work that our partners have been doing with the F1’s:

Edico Genome is deploying their DRAGEN Bio-IT Platform on F1 instances, with the expectation that it will provide whole-genome sequencing that runs in real time.

Ryft offers the Ryft Cloud, an accelerator for data analytics and machine learning that extends Elastic Stack. It sources data from Amazon Kinesis, Amazon Simple Storage Service (S3), Amazon Elastic Block Store (EBS), and local instance storage and uses massive bitwise parallelism to drive performance. The product supports high-level JDBC, ODBC, and REST interfaces along with low-level C, C++, Java, and Python APIs (see the Ryft API page for more information).

Reconfigure.io launched a cloud-based service that allows you to program FPGAs using the Go programming language. You can build, test, and deploy your code from within their cloud-based environment while taking advantage of concurrency-oriented language features such as goroutines (lightweight threads), channels, and selects.

NGCodec ported their RealityCodec video encoder to the F1 and used it to produce broadcast-quality video at 80 frames per second. Their solution can encode up to 32 independent video streams on a single F1 instance (read their new post, You Deserve Better than Grainy Giraffes, to learn more).

FPGAs In School & Research
Research groups and graduate classes at top-tier universities contacted us via AWS Educate and were eager to gain access to F1 instances.

UCLA‘s CS133 class (Parallel and Distributed Computing) is setting up an F1-based FPGA lab that will be operational within 3 or 4 weeks. According to UCLA Chancellor’s Professor Jason Cong, they are expanding multiple research projects to cover F1 including FPGA performance debugging, machine learning acceleration, Spark to FPGA compilation, and systolic array compilation.

Last month we announced that we are collaborating with the National Science Foundation (NSF) to foster innovation in big data research (read AWS Collaborates With the National Science Foundation to Foster Innovation to learn more and to find out how to apply for a grant).

FPGA’s in the AWS Marketplace
As I shared in my original post, we have built a complete beginning to end solution that lets developers build FPGA-powered applications and services and list them in the AWS Marketplace. I can’t wait to see what kinds of cool things show up there!

AWS Hot Startups – March 2017

Post Syndicated from Ana Visneski original https://aws.amazon.com/blogs/aws/aws-hot-startups-march-2017/

As the madness of March rounds up, take a break from all the basketball and check out the cool startups Tina Barr brings you for this month!

-Ana


The arrival of spring brings five new startups this month:

  • Amino Apps – providing social networks for hundreds of thousands of communities.
  • Appboy – empowering brands to strengthen customer relationships.
  • Arterys – revolutionizing the medical imaging industry.
  • Protenus – protecting patient data for healthcare organizations.
  • Syapse – improving targeted cancer care with shared data from across the country.

In case you missed them, check out February’s hot startups here.

Amino Apps (New York, NY)
Amino Logo
Amino Apps was founded on the belief that interest-based communities were underdeveloped and outdated, particularly when it came to mobile. CEO Ben Anderson and CTO Yin Wang created the app to give users access to hundreds of thousands of communities, each of them a complete social network dedicated to a single topic. Some of the largest communities have over 1 million members and are built around topics like popular TV shows, video games, sports, and an endless number of hobbies and other interests. Amino hosts communities from around the world and is currently available in six languages with many more on the way.

Navigating the Amino app is easy. Simply download the app (iOS or Android), sign up with a valid email address, choose a profile picture, and start exploring. Users can search for communities and join any that fit their interests. Each community has chatrooms, multimedia content, quizzes, and a seamless commenting system. If a community doesn’t exist yet, users can create it in minutes using the Amino Creator and Manager app (ACM). The largest user-generated communities are turned into their own apps, which gives communities their own piece of real estate on members’ phones, as well as in app stores.

Amino’s vast global network of hundreds of thousands of communities is run on AWS services. Every day users generate, share, and engage with an enormous amount of content across hundreds of mobile applications. By leveraging AWS services including Amazon EC2, Amazon RDS, Amazon S3, Amazon SQS, and Amazon CloudFront, Amino can continue to provide new features to their users while scaling their service capacity to keep up with user growth.

Interested in joining Amino? Check out their jobs page here.

Appboy (New York, NY)
In 2011, Bill Magnuson, Jon Hyman, and Mark Ghermezian saw a unique opportunity to strengthen and humanize relationships between brands and their customers through technology. The trio created Appboy to empower brands to build long-term relationships with their customers and today they are the leading lifecycle engagement platform for marketing, growth, and engagement teams. The team recognized that as rapid mobile growth became undeniable, many brands were becoming frustrated with the lack of compelling and seamless cross-channel experiences offered by existing marketing clouds. Many of today’s top mobile apps and enterprise companies trust Appboy to take their marketing to the next level. Appboy manages user profiles for nearly 700 million monthly active users, and is used to power more than 10 billion personalized messages monthly across a multitude of channels and devices.

Appboy creates a holistic user profile that offers a single view of each customer. That user profile in turn powers contextual cross-channel messaging, lifecycle engagement automation, and robust campaign insights and optimization opportunities. Appboy offers solutions that allow brands to create push notifications, targeted emails, in-app and in-browser messages, news feed cards, and webhooks to enhance the user experience and increase customer engagement. The company prides itself on its interoperability, connecting to a variety of complimentary marketing tools and technologies so brands can build the perfect stack to enable their strategies and experiments in real time.

AWS makes it easy for Appboy to dynamically size all of their service components and automatically scale up and down as needed. They use an array of services including Elastic Load Balancing, AWS Lambda, Amazon CloudWatch, Auto Scaling groups, and Amazon S3 to help scale capacity and better deal with unpredictable customer loads.

To keep up with the latest marketing trends and tactics, visit the Appboy digital magazine, Relate. Appboy was also recently featured in the #StartupsOnAir video series where they gave insight into their AWS usage.

Arterys (San Francisco, CA)
Getting test results back from a physician can often be a time consuming and tedious process. Clinicians typically employ a variety of techniques to manually measure medical images and then make their assessments. Arterys founders Fabien Beckers, John Axerio-Cilies, Albert Hsiao, and Shreyas Vasanawala realized that much more computation and advanced analytics were needed to harness all of the valuable information in medical images, especially those generated by MRI and CT scanners. Clinicians were often skipping measurements and making assessments based mostly on qualitative data. Their solution was to start a cloud/AI software company focused on accelerating data-driven medicine with advanced software products for post-processing of medical images.

Arterys’ products provide timely, accurate, and consistent quantification of images, improve speed to results, and improve the quality of the information offered to the treating physician. This allows for much better tracking of a patient’s condition, and thus better decisions about their care. Advanced analytics, such as deep learning and distributed cloud computing, are used to process images. The first Arterys product can contour cardiac anatomy as accurately as experts, but takes only 15-20 seconds instead of the 45-60 minutes required to do it manually. Their computing cloud platform is also fully HIPAA compliant.

Arterys relies on a variety of AWS services to process their medical images. Using deep learning and other advanced analytic tools, Arterys is able to render images without latency over a web browser using AWS G2 instances. They use Amazon EC2 extensively for all of their compute needs, including inference and rendering, and Amazon S3 is used to archive images that aren’t needed immediately, as well as manage costs. Arterys also employs Amazon Route 53, AWS CloudTrail, and Amazon EC2 Container Service.

Check out this quick video about the technology that Arterys is creating. They were also recently featured in the #StartupsOnAir video series and offered a quick demo of their product.

Protenus (Baltimore, MD)
Protenus Logo
Protenus founders Nick Culbertson and Robert Lord were medical students at Johns Hopkins Medical School when they saw first-hand how Electronic Health Record (EHR) systems could be used to improve patient care and share clinical data more efficiently. With increased efficiency came a huge issue – an onslaught of serious security and privacy concerns. Over the past two years, 140 million medical records have been breached, meaning that approximately 1 in 3 Americans have had their health data compromised. Health records contain a repository of sensitive information and a breach of that data can cause major havoc in a patient’s life – namely identity theft, prescription fraud, Medicare/Medicaid fraud, and improper performance of medical procedures. Using their experience and knowledge from former careers in the intelligence community and involvement in a leading hedge fund, Nick and Robert developed the prototype and algorithms that launched Protenus.

Today, Protenus offers a number of solutions that detect breaches and misuse of patient data for healthcare organizations nationwide. Using advanced analytics and AI, Protenus’ health data insights platform understands appropriate vs. inappropriate use of patient data in the EHR. It also protects privacy, aids compliance with HIPAA regulations, and ensures trust for patients and providers alike.

Protenus built and operates its SaaS offering atop Amazon EC2, where Dedicated Hosts and encrypted Amazon EBS volume are used to ensure compliance with HIPAA regulation for the storage of Protected Health Information. They use Elastic Load Balancing and Amazon Route 53 for DNS, enabling unique, secure client specific access points to their Protenus instance.

To learn more about threats to patient data, read Hospitals’ Biggest Threat to Patient Data is Hiding in Plain Sight on the Protenus blog. Also be sure to check out their recent video in the #StartupsOnAir series for more insight into their product.

Syapse (Palo Alto, CA)
Syapse provides a comprehensive software solution that enables clinicians to treat patients with precision medicine for targeted cancer therapies — treatments that are designed and chosen using genetic or molecular profiling. Existing hospital IT doesn’t support the robust infrastructure and clinical workflows required to treat patients with precision medicine at scale, but Syapse centralizes and organizes patient data to clinicians at the point of care. Syapse offers a variety of solutions for oncologists that allow them to access the full scope of patient data longitudinally, view recommended treatments or clinical trials for similar patients, and track outcomes over time. These solutions are helping health systems across the country to improve patient outcomes by offering the most innovative care to cancer patients.

Leading health systems such as Stanford Health Care, Providence St. Joseph Health, and Intermountain Healthcare are using Syapse to improve patient outcomes, streamline clinical workflows, and scale their precision medicine programs. A group of experts known as the Molecular Tumor Board (MTB) reviews complex cases and evaluates patient data, documents notes, and disseminates treatment recommendations to the treating physician. Syapse also provides reports that give health system staff insight into their institution’s oncology care, which can be used toward quality improvement, business goals, and understanding variables in the oncology service line.

Syapse uses Amazon Virtual Private Cloud, Amazon EC2 Dedicated Instances, and Amazon Elastic Block Store to build a high-performance, scalable, and HIPAA-compliant data platform that enables health systems to make precision medicine part of routine cancer care for patients throughout the country.

Be sure to check out the Syapse blog to learn more and also their recent video on the #StartupsOnAir video series where they discuss their product, HIPAA compliance, and more about how they are using AWS.

Thank you for checking out another month of awesome hot startups!

Easily Tag Amazon EC2 Instances and Amazon EBS Volumes on Creation

Post Syndicated from Craig Liebendorfer original https://aws.amazon.com/blogs/security/easily-tag-amazon-ec2-instances-and-amazon-ebs-volumes-on-creation/

In 2010, AWS launched resource tagging for Amazon EC2 instances and other EC2 resources. Since that launch, we have raised the allowable number of tags per resource from 10 to 50 and made tags more useful with the introduction of resource groups and Tag Editor. AWS customers use tags to track ownership, drive their cost accounting processes, implement compliance protocols, and control access to resources via AWS Identity and Access Management (IAM) policies.

The AWS tagging model provides separate functions for resource creation and resource tagging. Though this is flexible and has worked well for many of our users, it does result in a small time window when the resources exist in an untagged state. Using two separate functions means that it is possible for resource creation to succeed and tagging to fail, which would leave resources in an untagged state.

New this week, we have made tagging more flexible and more useful, with four new features:

  • Tag on creation – You can now specify tags for EC2 instances and Amazon Elastic Block Store (Amazon EBS) volumes as part of the API call that creates the resources.
  • Enforced tag usage – You can now write IAM policies that mandate the use of specific tags on EC2 instances and EBS volumes.
  • Resource-level permissions – By popular request, the CreateTags and DeleteTags functions now support IAM’s resource-level permissions.
  • Enforced volume encryption – You can now write IAM policies that mandate the use of encryption for newly created EBS volumes.

To learn more, see the full blog post on the AWS Blog.

How to Use Service Control Policies in AWS Organizations to Enforce Healthcare Compliance in Your AWS Account

Post Syndicated from Aaron Lima original https://aws.amazon.com/blogs/security/how-to-use-service-control-policies-in-aws-organizations-to-enforce-healthcare-compliance-in-your-aws-account/

AWS customers with healthcare compliance requirements such as the U.S. Health Insurance Portability and Accountability Act (HIPAA) and Good Laboratory, Clinical, and Manufacturing Practices (GxP) might want to control access to the AWS services their developers use to build and operate their GxP and HIPAA systems. For example, customers with GxP requirements might approve AWS as a supplier on the basis of AWS’s SOC certification and therefore want to ensure that only the services in scope for SOC are available to developers of GxP systems. Likewise, customers with HIPAA requirements might want to ensure that only AWS HIPAA Eligible Services are available to store and process protected health information (PHI). Now with AWS Organizations—policy-based management for multiple AWS accounts—you can programmatically control access to the services within your AWS accounts.

In this blog post, I show how to restrict an AWS account to HIPAA Eligible Services as well as explain why you should include additional supporting AWS services with service control policies (SCPs) in AWS Organizations. Although this example is HIPAA related, you can repurpose it for GxP, a database of Genotypes and Phenotypes (dbGaP) solutions, or other healthcare compliance requirements for which you want to control developers’ access to a specific scope of services.

Managing an account hierarchy with AWS Organizations

Let’s say I manage four AWS accounts: a Payer account, a Development account, a Corporate IT account, and a fourth account that contains PHI. In accordance with AWS’s Business Associate Agreement (BAA), I want to be sure that only AWS HIPAA Eligible Services are allowed in the fourth account along with supporting AWS services that help encrypt and control access to the account. The following diagram shows a logical view of the associated account structure.

Diagram showing the logical view of the account structure

As illustrated in the preceding diagram, Organizations allows me to create this account hierarchy between the four AWS accounts I manage. Before I proceed to show how to create and apply an SCP to the HIPAA account in this hierarchy, I’ll define some Organizations terminology that I use in this post:

  • Organization – A consolidated set of AWS accounts that you manage. For the preceding example, I have already created my organization and invited my accounts. For more information about creating an organization and inviting accounts, see AWS Organizations – Policy-Based Management for Multiple AWS Accounts.
  • Master account – The management hub for Organizations. This is where I invite existing accounts, create new accounts and manage my SCPs. I run all commands demonstrated in this post from this master account. This is also my payer account in the preceding account structure diagram.
  • Service control policy (SCP) – A set of controls that the organization’s master account can apply to the organization, selected OUs, and selected accounts. SCPs allow me to whitelist or blacklist services and actions that I can delegate to the users and roles in the account to which the SCPs are applied. The resultant security permissions for a user and role are the union of the permissions in an SCP and the permissions in an AWS Identity and Access Management (IAM) policy. I refer to SCPs as a policy type in some of this post’s command-line arguments.
  • Organizational unit (OU) – A container for a set of AWS accounts. OUs can be arranged into a hierarchy that can be as many as five levels deep. The top of the hierarchy of OUs is also known as the administrative root. In the walkthrough, I create a HIPAA OU and apply my policy to that OU. I then move the account into the OU to have the policy applied. To manage the organization depicted above, I might create OUs for my Corporate IT account and my Development account.

To restrict services in the fourth account to HIPAA Eligible Services and required supporting services, I will show how to create and apply an SCP to the account with the following steps:

  1. Create a JSON document that lists HIPAA Eligible Services and supporting AWS services.
  2. Create an SCP with a JSON document.
  3. Create an OU for the HIPAA account, and move the account into the OU.
  4. Attach the SCP to the HIPAA OU.
  5. Verify which SCPs are attached to the HIPAA OU.
  6. Detach the default FullAWSAccess SCP from the OU.
  7. Verify SCP enforcement.

How to create and apply an SCP to an account

Let’s walk through the steps to create an SCP and apply it to an account. I can manage my organization by using the Organizations console, AWS CLI, or AWS API from my master account. For the purposes of this post, I will demonstrate the creation and application of an SCP to my account by using the AWS CLI.

1.  Create a JSON document that lists HIPAA Eligible Services and supporting AWS services

Creating an SCP will be familiar if you have experience writing an IAM policy because the grammar in crafting the policy is similar. I will create a JSON document that lists only the services I want to allow in my account, and I will use this JSON document to create my SCP via the command line. The SCP I create from this document allows all actions for all resources of the listed services, effectively turning on only these services in my account. I name the document HIPAAExample.json and save it to the directory from which I will demonstrate the CLI commands.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                 "dynamodb:*","rds:*","ec2:*","s3:*","elasticmapreduce:*",
                 "glacier:*","elasticloadbalancing:*", "cloudwatch:*",
                 "importexport:*", "cloudformation:*", "redshift:*",
                 "iam:*", "health:*", "config:*", "snowball:*",
                 "trustedadvisor:*", "kms:*", "apigateway:*",
                 "autoscaling:*", "directconnect:*",
	         "execute-api:*", "sts:*"
             ],
             "Effect": "Allow",
             "Resource": "*"
        }
    ]
}

Note that the SCP includes more than just the HIPAA Eligible Services.

Why include additional supporting services in a HIPAA SCP?

You can use any service in your account, but you can use only HIPAA Eligible Services to store and process PHI. Some services, such as IAM and AWS Key Management Service (KMS), can be used because these services do not directly store or process PHI, but they might still be needed for administrative and security purposes.

To those ends, I include the following supporting services in the SCP to help me with account administration and security:

  • Access controls – I include IAM to ensure that I can manage access to resources in the account. Though Organizations can limit whether a service is available, I still need the granularity of access control that IAM provides.
  • Encryption – I need a way to encrypt the data. The integration of AWS KMS with Amazon Redshift, Amazon RDS, and Amazon Elastic Block Store (Amazon EBS) helps with this security requirement.
  • Auditing – I also need to be able to demonstrate controls in practice, track changes, and discover any malicious activity in my account. You will note that AWS CloudTrail is not included in the SCP, which prohibits any mutating actions against CloudTrail from users within the account. However, when setting up the account, CloudTrail was set up to send logs to a logging account as recommended in AWS Multiple Account Security Strategy. The logs do not reside in the account, and no one has privileges to change the trail including root or administrators, which helps ensure the protection of the API logging of the account. This highlights how SCPs can be used to secure services in an account.
  • Automation – Automation can help me with my security controls as shown in How to Translate HIPAA Controls to AWS CloudFormation Templates: Part 3 of the Automating HIPAA Compliance Series; therefore, I consider including AWS CloudFormation as a way to ensure that applications deployed in the account adhere to my security and compliance policies. Auto Scaling also is an important service to include to help me scale to meet demand and control cost.
  • Monitoring and support – The remaining services in the SCP such as Amazon CloudWatch are needed to make sure that I can monitor the environment and have visibility into the health of the workloads and applications in my AWS account, helping me maintain operational control. AWS Trusted Advisor is a service that helps to make sure that my cloud environment is well architected.

Now that I have created my JSON document with the services that I will include and explained in detail why I include them, I can create my SCP.

2.  Create an SCP with a JSON document

I will now create the SCP via the CLI with the aws organizations create-policy command. Using the name parameter, I name the SCP and define that I am creating an SCP, both of which are required parameters. I then provide a brief description of the SCP and specify the location of the JSON document I created in Step 1.

aws organizations create-policy --name hipaa-example-policy --type SERVICE_CONTROL_POLICY --description
 
"All HIPAA eligible services plus supporting AWS Services." --content file://./HIPAAExample.json

Output

{
    "policy": {
        "policySummary": {
            "type": "SERVICE_CONTROL_POLICY",
            "arn": "arn:aws:organizations::012345678900:policy/o-kzceys2q4j/SERVICE_CONTROL_POLICY/p-6ldl8bll",
            "name": "hipaa-example-policy",
            "awsManaged": false,
            "id": "p-6ldl8bll", "description": "All HIPAA eligible services and supporting AWS services."

I take note of the policy-id because I need it to attach the SCP to my OU in Step 4. Note: Throughout this post, fictitious placeholder values are shown for the purposes of demonstrating this post’s solution.

3.  Create an OU for the HIPAA account, and move the account into the OU

Grouping accounts by function will make it easier to manage the organization and apply policies across multiple accounts. In this step, I create an OU for the HIPAA account and move the target account into the OU. To create an OU, I need to know the ID for the parent object under which I will be placing the OU. In this case, I will place it under the root and need the ID for the root. To get the root ID, I run the list-roots command.

aws organizations list-roots

Output

{
    "Roots": [
        {
            "PolicyTypes": [
                {
                    "Status": "ENABLED", 
                    "Type": "SERVICE_CONTROL_POLICY"
                }
            ], 
            "Id": "r-rth4", 
            "Arn": "arn:aws:organizations::012345678900:root/o-p9bx61i0h1/r-rth4", 
            "Name": "Root"
        }
    ]
}

With the root ID, I can proceed to create the OU under the root.

aws organizations create-organizational-unit --parent-id r-rth4 --name HIPAA-Accounts

Output

{
    "OrganizationalUnit": {
       "Id": "ou-rth4-ezo5wonz", 
        "Arn": "arn:aws:organizations::012345678900:ou/o-p9bx61i0h1/ou-rth4-ezo5wonz", 
        "Name": "HIPAA-Accounts"
    }
}

I take note of the OU ID in the output because I need it in the next command to move my target account. I will also need the root ID in the command because I am moving the target account from the root into the OU.

aws organizations move-account --account-id 098765432110 --source-parent-id r-rth4 --destination-parent-id 
ou-rth4-ezo5wonz

No Output

 

4.  Attach the SCP to the HIPAA OU

Even though you may have enabled All Features in your organization, you still need to enable SCPs at the root level of the organization to attach SCPs to objects. To do this in my case, I will run the enable-policy-type command and provide the root ID.

aws organizations enable-policy-type --root-id r-rth4 --policy-type SERVICE_CONTROL_POLICY

Output

{
    "Root": {
        "PolicyTypes": [], 
        "Id": "r-rth4", 
        "Arn": "arn:aws:organizations::012345678900:root/o-p9bx61i0h1/r-rth4", 
        "Name": "Root"
    }
}

Now, I will attach the SCP to the OU by using the aws organizations attach-policy command. I must include the target-id, which is the OU ID noted in the previous step and the policy-id from the output of the command in Step 2.

aws organizations attach-policy --target-id ou-rth4-ezo5wonz --policy-id p-6ldl8bll

No Output

 

5.  Verify which SCPs are attached to the HIPAA OU

I will now verify which SCPs are attached to my account by using the aws organization list-policies-for-target command. I must provide the OU ID with the target-id parameter and then filter for SERVICE_CONTROL_POLICY type.

aws organizations list-policies-for-target --target-id ou-rth4-ezo5wonz --filter SERVICE_CONTROL_POLICY

Output

{
    "policies": [
        {
            "awsManaged": false,
            "arn": "arn:aws:organizations::012345678900:policy/o-kzceys2q4j/SERVICE_CONTROL_POLICY/p-6ldl8bll",
            "id": "p-6ldl8bll",
            "description": "All HIPAA eligible services plus supporting AWS Services.",
            "name": "hipaa-example-policy",
            "type": "SERVICE_CONTROL_POLICY"
        },
        {
            "awsManaged": true,
            "arn": "arn:aws:organizations::aws:policy/SERVICE_CONTROL_POLICY/p-FullAWSAccess",
            "id": "p-FullAWSAccess",
            "description": "Allows access to every operation",
            "name": "FullAWSAccess",
            "type": "SERVICE_CONTROL_POLICY"
        }
    ]
}

As the output shows, two SCPs are attached to this account. I want to detach the FullAWSAccess SCP so that the HIPAA SCP is properly in effect. The FullAWSAccess SCP is an Allow SCP that allows all AWS services. If I were to leave the default FullAWSAccess SCP in place, it would grant access to services I do not want to allow in my account. Detaching the FullAWSAccess SCP means that only the services I allow in the hipaa-example-policy are allowed in my account. Note that if I were to create a Deny SCP, the SCP would take precedence over an Allow SCP.

6.  Detach the default FullAWSAccess SCP from the OU

Before detaching the default FullAWSAccess SCP from my account, I run the aws workspaces describe-workspaces call from the Amazon WorkSpaces API. I am currently not running any WorkSpaces, so the output shows an empty list. However, I will test this again after I detach the FullAWSAccess SCP from my account and am left with only the HIPAA SCP attached to the account.

aws workspaces describe-workspaces

Output

{
    "Workspaces": []
}

In order to detach the FullAWSAccess SCP, I must run the aws organizations detach-policy command, providing it the policy-id and target-id of the OU.

aws organizations detach-policy --policy-id p-FullAWSAccess --target-id ou-rth4-ezo5wonz

No Output

 

If I rerun the list-policies-for-target command again, I see that only one SCP is attached to my account that allows HIPAA Eligible Services, as shown in the following output.

aws organizations list-policies-for-target --target-id ou-rth4-ezo5wonz --filter SERVICE_CONTROL_POLICY

Output

 

{
    "policies": [
        {
            "name": "hipaa-example-policy",
            "arn": "arn:aws:organizations::012345678900:policy/o-kzceys2q4j/SERVICE_CONTROL_POLICY/p-6ldl8bll",
            "description": "All HIPAA eligible services plus supporting AWS Services.",
            "awsManaged": false,
            "id": "p-6ldl8bll",
            "type": "SERVICE_CONTROL_POLICY"
        }
    ]
}

Now I can test and verify the enforcement of this SCP.

7.  Verify SCP enforcement

Previously, the administrator of the account had full access to all AWS services, including Amazon WorkSpaces. His IAM policy for Amazon WorkSpaces allows all actions for Amazon WorkSpaces. However, after I apply the HIPAA SCP to the account, this changes the effect of the IAM policy to deny all actions for Amazon WorkSpaces because it is not an allowed service.

The following screenshot of the IAM policy simulator shows which permissions are set for the administrator after I apply the HIPAA SCP. Also, note that the IAM policy simulator shows that the Deny permission is being denied by Organizations. Because the policy simulator is aware of the SCPs attached to an account, it is a good tool to use when troubleshooting or validating an SCP.

If I run the aws workspaces describe-workspaces call again as I did in Step 5, this time I receive an AccessDeniedException error, which validates that the HIPAA SCP is working because Amazon WorkSpaces is not an allowed service in the SCP.

aws workspaces describe-workspaces

Output

An error occurred (AccessDeniedException) when calling the DescribeWorkspaces operation: 
User: arn:aws:iam::098765432110:user/admin is not authorized to perform: workspaces:DescribeWorkspaces 
on resource: arn:aws:workspaces:us-east-1:098765432110:workspace/*

This completes the process of creating and applying an SCP to my account.

Summary

In this blog post, I have shown how to create an SCP and attach it to an OU to restrict an account to HIPAA Eligible Services and additional supporting services. I also showed how to create an OU, move an account into the OU, and then validate the SCP attached to the OU. For more information, see AWS Cloud Computing in Healthcare.

New – Tag EC2 Instances & EBS Volumes on Creation

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/new-tag-ec2-instances-ebs-volumes-on-creation/

Way back in 2010, we launched Resource Tagging for EC2 instances and other EC2 resources. Since that launch, we have raised the allowable number of tags per resource from 10 to 50, and we have made tags more useful with the introduction of resource groups and a tag editor. Our customers use tags to track ownership, drive their cost accounting processes, implement compliance protocols, and to control access to resources via IAM policies.

The AWS tagging model provides separate functions for resource creation and resource tagging. While this is flexible and has worked well for many of our users, it does result in a small time window where the resources exist in an untagged state. Using two separate functions means that resource creation could succeed only for tagging to fail, again leaving resources in an untagged state.

Today we are making tagging more flexible and more useful, with four new features:

Tag on Creation – You can now specify tags for EC2 instances and EBS volumes as part of the API call that creates the resources.

Enforced Tag Usage – You can now write IAM policies that mandate the use of specific tags on EC2 instances or EBS volumes.

Resource-Level Permissions – By popular request, the CreateTags and DeleteTags functions now support IAM’s resource-level permissions.

Enforced Volume Encryption – You can now write IAM policies that mandate the use of encryption for newly created EBS volumes.

Tag on Creation
You now have the ability to specify tags for EC2 instances and EBS volumes as part of the API call that creates the resources (if the call creates both instances and volumes, you can specify distinct tags for the instance and for each volume). The resource creation and the tagging are performed atomically; both must succeed in order for the operation (RunInstances, CreateVolume, and other functions that create resources) to succeed. You no longer need to build tagging scripts that run after instances or volumes have been created.

Here’s how you specify tags when you launch an EC2 instance (the CostCenter and SaveSnapshotFlag tags are also set on any EBS volumes created when the instance is launched):

To learn more, read Using Tags.

Resource-Level Permissions
CreateTags and DeleteTags now support IAM’s resource-level permissions, as requested by many customers. This gives you additional control over the tag keys and values on existing resources.

Also, RunInstances and CreateVolume now support additional resource-level permissions. This allows you to exercise control over the users and groups that can tag resources on creation.

To learn more, see Example Policies for Working with the AWS CLI or an AWS SDK.

Enforced Tag Usage
You can now write IAM policies that enforce the use of specific tags. For example, you could write a policy that blocks the deletion of tags named Owner or Account. Or, you could write a “Deny” policy that disallows the creation of new tags for specific existing resources. You could also use an IAM policy to enforce the use of Department and CostCenter tags to help you achieve more accurate cost allocation reporting. In order to implement stronger compliance and security policies, you could also restrict access to DeleteTags if the resource is not tagged with the user’s name. The ability to enforce tag usage gives you precise control over access to resources, ownership, and cost allocation.

Here’s a statement that requires the use of costcenter and stack tags (with values of “115” and “prod,” respectively) for all newly created volumes:

"Statement": [
    {
      "Sid": "AllowCreateTaggedVolumes",
      "Effect": "Allow",
      "Action": "ec2:CreateVolume",
      "Resource": "arn:aws:ec2:us-east-1:123456789012:volume/*",
      "Condition": {
        "StringEquals": {
          "aws:RequestTag/costcenter": "115",
          "aws:RequestTag/stack": "prod"
         },
         "ForAllValues:StringEquals": {
             "aws:TagKeys": ["costcenter","stack"]
         }
       }
     },
     {
       "Effect": "Allow",
       "Action": [
         "ec2:CreateTags"
       ],
       "Resource": "arn:aws:ec2:us-east-1:123456789012:volume/*",
       "Condition": {
         "StringEquals": {
             "ec2:CreateAction" : "CreateVolume"
        }
      }
    }
  ]

Enforced Volume Encryption
Using the additional IAM resource-level permissions now supported by RunInstances and CreateVolume, you can now write IAM policies that mandate the use of encryption for any EBS boot or data volumes created. You can use this to comply with regulatory requirements, enforce enterprise security policies, and to protect your data in compliance with applicable auditing requirements.

Here’s a sample statement that you can incorporate into an IAM policy for RunInstances and CreateVolume to enforce EBS volume encryption:

"Statement": [
        {
            "Effect": "Deny",
            "Action": [
                       "ec2:RunInstances",
                       "ec2:CreateVolume"
            ],
            "Resource": [
                "arn:aws:ec2:*:*:volume/*"
            ],
            "Condition": {
                "Bool": {
                    "ec2:Encrypted": "false"
                }
            }
        },

To learn more and to see some sample policies, take a look at Example Policies for Working with the AWS CLI or an AWS SDK and IAM Policies for Amazon EC2.

Available Now
As you can see, the combination of tagging and the new resource-level permissions on the resource creation and tag manipulation functions gives you the ability to track and control access to your EC2 resources.

This new feature is available now in all regions except AWS GovCloud (US) and China (Beijing). You can start using it today from the AWS Management Console, AWS Command Line Interface (CLI), AWS Tools for Windows PowerShell, or the AWS APIs.

We are planning to add support for additional EC2 resource types over time; stay tuned for more information!

Amazon EBS Update – New Elastic Volumes Change Everything

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/amazon-ebs-update-new-elastic-volumes-change-everything/

It is always interesting to speak with our customers and to learn how the dynamic nature of their business and their applications drives their block storage requirements. These needs change over time, creating the need to modify existing volumes to add capacity or to change performance characteristics. Today’s 24×7 operating models leaves no room for downtime; as a result, customers want to make changes without going offline or otherwise impacting operations.

Over the years, we have introduced new EBS offerings that support an ever-widening set of use cases. For example, we introduced two new volume types in 2016 – Throughput Optimized HDD (st1) and Cold HDD (sc1). Our customers want to use these volume types as storage tiers, modifying the volume type to save money or to change the performance characteristics, without impacting operations.

In other words, our customers want their EBS volumes to be even more elastic!

New Elastic Volumes
Today we are launching a new EBS feature we call Elastic Volumes and making it available for all current-generation EBS volumes attached to current-generation EC2 instances. You can now increase volume size, adjust performance, or change the volume type while the volume is in use. You can continue to use your application while the change takes effect.

This new feature will greatly simplify (or even eliminate) many of your planning, tuning, and space management chores. Instead of a traditional provisioning cycle that can take weeks or months, you can make changes to your storage infrastructure instantaneously, with a simple API call.

You can address the following scenarios (and many more that you can come up with on your own) using Elastic Volumes:

Changing Workloads – You set up your infrastructure in a rush and used the General Purpose SSD volumes for your block storage. After gaining some experience you figure out that the Throughput Optimized volumes are a better fit, and simply change the type of the volume.

Spiking Demand – You are running a relational database on a Provisioned IOPS volume that is set to handle a moderate amount of traffic during the month, with a 10x spike in traffic  during the final three days of each month due to month-end processing.  You can use Elastic Volumes to dial up the provisioning in order to handle the spike, and then dial it down afterward.

Increasing Storage – You provisioned a volume for 100 GiB and an alarm goes off indicating that it is now at 90% of capacity. You increase the size of the volume and expand the file system to match, with no downtime, and in a fully automated fashion.

Using Elastic Volumes
You can manage all of this from the AWS Management Console, via API calls, or from the AWS Command Line Interface (CLI).

To make a change from the Console, simply select the volume and choose Modify Volume from the Action menu:

Then make any desired changes to the volume type, size, and Provisioned IOPS (if appropriate). Here I am changing my 75 GiB General Purpose (gp2) volume into a 400 GiB Provisioned IOPS volume, with 20,000 IOPS:

When I click on Modify I confirm my intent, and click on Yes:

The volume’s state reflects the progress of the operation (modifying, optimizing, or complete):

The next step is to expand the file system so that it can take advantage of the additional storage space. To learn how to do that, read Expanding the Storage Space of an EBS Volume on Linux or Expanding the Storage Space of an EBS Volume on Windows. You can expand the file system as soon as the state transitions to optimizing (typically a few seconds after you start the operation). The new configuration is in effect at this point, although optimization may continue for up to 24 hours. Billing for the new configuration begins as soon as the state turns to optimizing (there’s no charge for the modification itself).

Automatic Elastic Volume Operations
While manual changes are fine, there’s plenty of potential for automation. Here are a couple of ideas:

Right-Sizing – Use a CloudWatch alarm to watch for a volume that is running at or near its IOPS limit. Initiate a workflow and approval process that could provision additional IOPS or change the type of the volume. Or, publish a “free space” metric to CloudWatch and use a similar approval process to resize the volume and the filesystem.

Cost Reduction – Use metrics or schedules to reduce IOPS or to change the type of a volume. Last week I spoke with a security auditor at a university. He collects tens of gigabytes of log files from all over campus each day and retains them for 60 days. Most of the files are never read, and those that are can be scanned at a leisurely pace. They could address this use case by creating a fresh General Purpose volume each day, writing the logs to it at high speed, and then changing the type to Throughput Optimized.

As I mentioned earlier, you need to resize the file system in order to be able to access the newly provisioned space on the volume. In order to show you how to automate this process, my colleagues built a sample that makes use of CloudWatch Events, AWS Lambda, EC2 Systems Manager, and some PowerShell scripting. The rule matches the modifyVolume event emitted by EBS and invokes the logEvents Lambda function:

The function locates the volume, confirms that it is attached to an instance that is managed by EC2 Systems Manager, and then adds a “maintenance tag” to the instance:

def lambda_handler(event, context):
    volume =(event['resources'][0].split('/')[1])
    attach=ec2.describe_volumes(VolumeIds=[volume])['Volumes'][0]['Attachments']
    if len(attach)>0: 
        instance = attach[0]['InstanceId']
        filter={'key': 'InstanceIds', 'valueSet': [instance]}
        info = ssm.describe_instance_information(InstanceInformationFilterList=[filter])['InstanceInformationList']
        if len(info)>0:
            ec2.create_tags(Resources=[instance],Tags=[tags])
            print (info[0]['PlatformName']+' Instance '+ instance+ ' has been tagged for maintenance' )

Later (either manually or on a schedule), EC2 Systems Manager is used to run a PowerShell script on all of the instances that are tagged for maintenance. The script looks at the instance’s disks and partitions, and resizes all of the drives (filesystems) to the maximum allowable size. Here’s an excerpt:

foreach ($DriveLetter in $DriveLetters) {
	$Error.Clear()
        $SizeMax = (Get-PartitionSupportedSize -DriveLetter $DriveLetter).SizeMax
}

To learn more, take a look at the [[Elastic Volume Sample]].

Available Today
The Elastic Volumes feature is available today and you can start using it right now!
