New – Encryption of Data in Transit for Amazon EFS

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/new-encryption-of-data-in-transit-for-amazon-efs/

Amazon Elastic File System was designed to be the file system of choice for cloud-native applications that require shared access to file-based storage. We launched EFS in mid-2016 and have added several important features since then including on-premises access via Direct Connect and encryption of data at rest. We have also made EFS available in additional AWS Regions, most recently US West (Northern California). As was the case with EFS itself, these enhancements were made in response to customer feedback, and reflect our desire to serve an ever-widening customer base.

Encryption in Transit
Today we are making EFS even more useful with the addition of support for encryption of data in transit. When used in conjunction with the existing support for encryption of data at rest, you now have the ability to protect your stored files using a defense-in-depth security strategy.

In order to make it easy for you to implement encryption in transit, we are also releasing an EFS mount helper. The helper (available in source code and RPM form) takes care of setting up a TLS tunnel to EFS, and also allows you to mount file systems by ID. The two features are independent; you can use the helper to mount file systems by ID even if you don’t make use of encryption in transit. The helper also supplies a recommended set of default options to the actual mount command.

Setting up Encryption
I start by installing the EFS mount helper on my Amazon Linux instance:

$ sudo yum install -y amazon-efs-utils

Next, I visit the EFS Console and capture the file system ID:

Then I specify the ID (and the TLS option) to mount the file system:

$ sudo mount -t efs fs-92758f7b -o tls /mnt/efs

And that’s it! The encryption is transparent and has an almost negligible impact on data transfer speed.

Available Now
You can start using encryption in transit today in all AWS Regions where EFS is available.

The mount helper is available for Amazon Linux. If you are running another distribution of Linux you will need to clone the GitHub repo and build your own RPM, as described in the README.

AWS Achieves Spain’s ENS High Certification Across 29 Services

Post Syndicated from Oliver Bell original https://aws.amazon.com/blogs/security/aws-achieves-spains-ens-high-certification-across-29-services/

AWS has achieved Spain’s Esquema Nacional de Seguridad (ENS) High certification across 29 services. To successfully achieve the ENS High Standard, BDO España conducted an independent audit and attested that AWS meets confidentiality, integrity, and availability standards. This provides the assurance needed by Spanish Public Sector organizations wanting to build secure applications and services on AWS.

The National Security Framework, regulated under Royal Decree 3/2010, was developed through close collaboration between ENAC (Entidad Nacional de Acreditación), the Ministry of Finance and Public Administration and the CCN (National Cryptologic Centre), and other administrative bodies.

The following AWS Services are ENS High accredited across our Dublin and Frankfurt Regions:

  • Amazon API Gateway
  • Amazon DynamoDB
  • Amazon Elastic Container Service
  • Amazon Elastic Block Store
  • Amazon Elastic Compute Cloud
  • Amazon Elastic File System

EFS File Sync – Faster File Transfer To Amazon EFS File Systems

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/efs-file-sync-faster-file-transfer-to-amazon-efs-file-systems/

We launched EFS File Sync a few days before AWS re:Invent 2017 and I finally have time to tell you about it!

If you need to move a large collection of files from an on-premises or in-cloud file system to Amazon Elastic File System, this tool is for you. Simple, single-threaded command line tools such as cp and rsync predate the cloud and cannot deliver the throughput required to move massive amounts of data from place to place. These tools are generally used as building blocks, often within scripts that take care of scheduling, orchestration, and network security.

Secure & Parallel
EFS File Sync uses a secure, highly parallel data transfer mechanism that can run up to 5 times faster than the tools I mentioned above. It is available as an agent that runs within VMware ESXi or on an EC2 instance, and accesses the source file system via NFS (v3 and v4), and can be used in all AWS Regions where EFS is available. Because the agent is responsible for initiating all communication with AWS you don’t need to set up VPNs or allow inbound connections through your firewall.

You can launch, control, and monitor the agent and your sync tasks from the AWS Management Console. Jobs can specify the transfer of an entire file system or a specific directory tree, with the option to detect and skip files that are already present in the destination. File metadata (modification and access time, POSIX ownership and permissions, symbolic links, and hard links) is also copied.

Using EFS File Sync
In order to write this blog post, I launched an EC2 instance, exported an NFS file system (/data), and populated the file system with the Linux kernel source code.

I open the EFS Console in the same Region as my instance, and click File syncs:

I click on Get started, choose Amazon EC2 as my host platform and click Launch instance, and click Connect to agent to proceed:

Clicking Launch instance opens the EC2 console in a separate tab. I pick a Memory optimized instance type (xlarge or bigger), configure it with a public IP address and with a security group that allows inbound traffic on port 80, and launch it as I would any other EC2 instance. Then I wait a minute or two (time to water my plants or check on my dog), and wait until the status checks pass:

Then I capture the instance’s public IP address, return to the EFS tab, enter the address, and click on Activate agent:

This step retrieves the activation key from the sync agent. After it completes, I enter a name for it and click Activate agent to proceed:

Now that the agent is running and activated, I click on Create sync task to start moving some files to EFS:

I configure the source location (the EC2 instance that I mentioned at the start of this section):

I also choose the destination EFS file system and specify a target location within it for my files:

Then I select my sync options and click Next to review my configuration:

The review looks good and I click Create sync task to start copying my files:

After the sync task has been created and its status becomes Available, I can select it and choose Start from the Actions menu to initiate a sync:

I fine-tune the settings that I established when I created the task, and click Start to proceed:

I can track the status of the sync task on the History tab:

It completes within minutes and my EFS file system now includes the new files:

Available Now
EFS File Sync is available in all AWS Regions where EFS is available. You pay for the EFS and EC2 resources that you consume and $0.01 per GB of data copied (see the EFS Pricing page for more info).

New – Encryption of Data at Rest for Amazon Elastic File System (EFS)

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/new-encryption-at-rest-for-amazon-elastic-file-system-efs/

We launched Amazon Elastic File System in production form a little over a year ago (see Amazon Elastic File System – Production Ready in Three Regions for more information). Later in the year we added On-Premises access via Direct Connect and made EFS available in the US East (Ohio) Region, following up this year with availability in the EU (Frankfurt) and Asia Pacific (Sydney) Regions.

Encryption at Rest
Today we are adding support for encryption of data at rest. When you create a new file system, you can select a key that will be used to encrypt the contents of the files that you store on the file system. The key can be a built-in key that is managed by AWS or a key that you created yourself using AWS Key Management Service (KMS). File metadata (file names, directory names, and directory contents) will be encrypted using a key managed by AWS. Both forms of encryption are implemented using an industry-standard AES-256 algorithm.

You can set this up in seconds when you create a new file system. You simply choose the built-in key (aws/elasticfilesystem) or one of your own:

EFS will take care of the rest! You can select the filesystem in the console to verify that it is encrypted as desired:

A cryptographic algorithm that meets the approval of FIPS 140-2 is used to encrypt data and metadata. The encryption is transparent and has a minimal effect on overall performance.

You can use AWS Identity and Access Management (IAM) to control access to the Customer Master Key (CMK). The CMK must be enabled in order to grant access to the file system; disabling the key prevents it from being used to create new file systems and blocks access (after a period of time) to existing file systems that it protects. To learn more about your options, read Managing Access to Encrypted File Systems.

Available Now
Encryption of data at rest is available now in all regions where EFS is supported, at no additional charge.

New – AWS Resource Tagging API

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/new-aws-resource-tagging-api/

AWS customers frequently use tags to organize their Amazon EC2 instances, Amazon EBS volumes, Amazon S3 buckets, and other resources. Over the past couple of years we have been working to make tagging more useful and more powerful. For example, we have added support for tagging during Auto Scaling, the ability to use up to 50 tags per resource, console-based support for the creation of resources that share a common tag (also known as resource groups), and the option to use Config Rules to enforce the use of tags.

As customers grow to the point where they are managing thousands of resources, each with up to 50 tags, they have been looking to us for additional tooling and options to simplify their work. Today I am happy to announce that our new Resource Tagging API is now available. You can use these APIs from the AWS SDKs or via the AWS Command Line Interface (CLI). You now have programmatic access to the same resource group operations that had been accessible only from the AWS Management Console.

Recap: Console-Based Resource Group Operations
Before I get in to the specifics of the new API functions, I thought you would appreciate a fresh look at the console-based grouping and tagging model. I already have the ability to find and then tag AWS resources using a search that spans one or more regions. For example, I can select a long list of regions and then search them for my EC2 instances like this:

After I locate and select all of the desired resources, I can add a new tag key by clicking Create a new tag key and entering the desired tag key:

Then I enter a value for each instance (the new ProjectCode column):

Then I can create a resource group that contains all of the resources that are tagged with P100:

After I have created the resource group, I can locate all of the resources by clicking on the Resource Groups menu:

To learn more about this feature, read Resource Groups and Tagging for AWS.

New API for Resource Tagging
The API that we are announcing today gives you power to tag, untag, and locate resources using tags, all from your own code. With these new API functions, you are now able to operate on multiple resource types with a single set of functions.

Here are the new functions:

TagResources – Add tags to up to 20 resources at a time.

UntagResources – Remove tags from up to 20 resources at a time.

GetResources – Get a list of resources, with optional filtering by tags and/or resource types.

GetTagKeys – Get a list of all of the unique tag keys used in your account.

GetTagValues – Get all tag values for a specified tag key.

These functions support the following AWS services and resource types:

AWS Service Resource Types
Amazon CloudFront Distribution.
Amazon EC2 AMI, Customer Gateway, DHCP Option, EBS Volume, Instance, Internet Gateway, Network ACL, Network Interface, Reserved Instance, Reserved Instance Listing, Route Table, Security Group – EC2 Classic, Security Group – VPC, Snapshot, Spot Batch, Spot Instance Request, Spot Instance, Subnet, Virtual Private Gateway, VPC, VPN Connection.
Amazon ElastiCache Cluster, Snapshot.
Amazon Elastic File System Filesystem.
Amazon Elasticsearch Service Domain.
Amazon EMR Cluster.
Amazon Glacier Vault.
Amazon Inspector Assessment.
Amazon Kinesis Stream.
Amazon Machine Learning Batch Prediction, Data Source, Evaluation, ML Model.
Amazon Redshift Cluster.
Amazon Relational Database Service DB Instance, DB Option Group, DB Parameter Group, DB Security Group, DB Snapshot, DB Subnet Group, Event Subscription, Read Replica, Reserved DB Instance.
Amazon Route 53 Domain, Health Check, Hosted Zone.
Amazon S3 Bucket.
Amazon WorkSpaces WorkSpace.
AWS Certificate Manager Certificate.
AWS CloudHSM HSM.
AWS Directory Service Directory.
AWS Storage Gateway Gateway, Virtual Tape, Volume.
Elastic Load Balancing Load Balancer, Target Group.

Things to Know
Here are a couple of things to keep in mind when you build code or write scripts that use the new API functions or the CLI equivalents:

Compatibility – The older, service-specific functions remain available and you can continue to use them.

Write Permission – The new tagging API adds another layer of permission on top of existing policies that are specific to a single AWS service. For example, you will need to have access to tag:tagResources and EC2:createTags in order to add a tag to an EC2 instance.

Read Permission – You will need to have access to tag:GetResources, tag:GetTagKeys, and tag:GetTagValues in order to call functions that access tags and tag values.

Pricing – There is no charge for the use of these functions or for tags.

Available Now
The new functions are supported by the latest versions of the AWS SDKs. You can use them to tag and access resources in all commercial AWS regions.

NICE EnginFrame – User-Friendly HPC on AWS

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/nice-enginframe-user-friendly-hpc-on-aws/

Last year I announced that AWS had signed an agreement to acquire NICE, and that we planned to work together to create even better tools and services for high performance and scientific computing.

Today I am happy to be able to tell you about the launch of NICE EnginFrame 2017. This product is designed to simplify the process of setting up and running technical and scientific applications that take advantage of the power, scale, and flexibility of the AWS Cloud. You can set up a fully functional HPC cluster in less than an hour and then access it through a simple web-based user interface. If you are already familiar with and using EnginFrame, you can keep running it on-premises or make the move to the cloud.

AWS Inside
Your clusters (you can launch more than one if you’d like) reside within a Virtual Private Cloud (VPC) and are built using multiple AWS services and features including Amazon Elastic Compute Cloud (EC2) instances running the Amazon Linux AMI, Amazon Elastic File System for shared, NFS-style file storage, AWS Directory Service for user authentication, and Application Load Balancers for traffic management. These managed services allow you to focus on your workloads and your work. You don’t have to worry about system software upgrades, patches, scaling of processing or storage, or any of the other responsibilities that you’d have if you built and ran your own clusters.

EnginFrame is launched from a AWS CloudFormation template. The template is parameterized and self-contained, and helps to ensure that every cluster you launch will be configured in the same way. The template creates two separate CloudFormation stacks (collections of AWS resources) when you run it:

Main Stack – This stack hosts the shared, EFS-based storage for your cluster and an Application Load Balancer that routes incoming requests to the Default Cluster Stack. The stack is also host to a set of AWS Lambda functions that take care of setting up and managing IAM Roles and SSL certificates.

Default Cluster Stack – This stack is managed by the Main Stack and is where the heavy lifting takes place. The cluster is powered by CfnCluster and scales up and down as needed, terminating compute nodes when they are no longer needed. It also runs the EnginFrame portal.

EnginFrame Portal
After you launch your cluster, you will interact with it using the web-based EnginFrame portal. The portal will give you access to your applications (both batch and interactive), your data, and your jobs. You (or your cluster administrator) can create templates for batch applications and associate actions for specific file types.

EnginFrame includes an interactive file manager and a spooler view that lets you track the output from your jobs. In this release, NICE added a new file uploader that allows you to upload several files at the same time. The file uploader can also reduce upload time by caching commonly used files.

Running EnginFrame
In order to learn more about EnginFrame and to see how it works, I started at the EnginFrame Quick Start on AWS page, selected the US East (Northern Virginia) Regions, and clicked on Agree and Continue:

After logging in to my AWS account, I am in the CloudFormation Console. The URL to the CloudFormation template is already filled in, so I click on Next to proceed:

Now I configure my stack. I give it a name, set up the network configuration, and enter a pair of passwords:

I finish by choosing an EC2 key pair (if I was a new EC2 user I would have to create and download it first), and setting up the configuration for my cluster. Then I click on Next:

I enter a tag (a key and a value) for tracking purposes, but leave the IAM Role and the Advanced options as-is, and click on Next once more:

On the next page, I review my settings (not shown), and acknowledge that CloudFormation will create some IAM resources on my behalf. Then I click on Create to get things started:

 

CloudFormation proceeds to create, configure, and connect all of the necessary AWS resources (this is a good time to walk your dog or say hello to your family; the process takes about half an hour):

When the status of the EnginFrame cluster becomes CREATE_COMPLETE, I can click on it, and then open up the Outputs section in order to locate the EnginFrameURL:

Because the URL references an Application Load Balancer with a self-signed SSL certificate, I need to confirm my intent to visit the site:

EnginFrame is now running on the CloudFormation stack that I just launched. I log in with user name efadmin and the password that I set when I created the stack:

From here I can create a service. I’ll start simple, with a service that simply compresses an uploaded file. I click on Admin’s Portal in the blue title bar, until I get to here:

Then I click on Manage, Services, and New to define my service:

I click on Submit, choose the Job Script tab, add one line to the end of the default script, and Close the action window:

Then I Save the new service and click on Test Run in order to verify that it works as desired. I upload a file from my desktop and click on Submit to launch the job:

The job is then queued for execution on my cluster:

This just scratches the surface of what EnginFrame can do, but it is all that I have time for today.

Availability and Pricing
EnginFrame 2017 is available now and you can start using it today. You pay for the AWS resources that you use (EC2 instances, EFS storage, and so forth) and can use EnginFrame at no charge during the initial 90 day evaluation period. After that, EnginFrame is available under a license that is based on the number of concurrent users.

Amazon EFS Update – On-Premises Access via Direct Connect

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/amazon-efs-update-on-premises-access-via-direct-connect-vpc/

I introduced you to Amazon Elastic File System last year (Amazon Elastic File System – Shared File Storage for Amazon EC2) and announced production readiness earlier this year (Amazon Elastic File System – Production-Ready in Three Regions). Since the launch earlier this year, thousands of AWS customers have used it to set up, scale, and operate shared file storage in the cloud.

Today we are making EFS even more useful with the introduction of simple and reliable on-premises access via AWS Direct Connect. This has been a much-requested feature and I know that it will be useful for migration, cloudbursting, and backup. To use this feature for migration, you simply attach an EFS file system to your on-premises servers, copy your data to it, and then process it in the cloud as desired, leaving your data in AWS for the long term.  For cloudbursting, you would copy on-premises data to an EFS file system, analyze it at high speed using a fleet of Amazon Elastic Compute Cloud (EC2) instances, and then copy the results back on-premises or visualize them in Amazon QuickSight.

You’ll get the same file system access semantics including strong consistency and file locking, whether you access your EFS file systems from your on-premises servers or from your EC2 instances (of course, you can do both concurrently). You will also be able to enjoy the same multi-AZ availability and durability that is part-and-parcel of EFS.

In order to take advantage of this new feature, you will need to use Direct Connect to set up a dedicated network connection between your on-premises data center and an Amazon Virtual Private Cloud. Then you need to make sure that your filesystems have mount targets in subnets that are reachable via the Direct Connect connection:

You also need to add a rule to the mount target’s security group in order to allow inbound TCP and UDP traffic to port 2049 (NFS) from your on-premises servers:

After you create the file system, you can reference the mount targets by their IP addresses, NFS-mount them on-premises, and start copying files. The IP addresses are available from within the AWS Management Console:

The Management Console also provides you with access to step-by-step directions! Simply click on the On-premises mount instructions:

And follow along:

This feature is available today at no extra charge in the US East (Northern Virginia), US West (Oregon), EU (Ireland), and US East (Ohio) Regions.

How to Assign Permissions Using New AWS Managed Policies for Job Functions

Post Syndicated from Joy Chatterjee original https://aws.amazon.com/blogs/security/how-to-assign-permissions-using-new-aws-managed-policies-for-job-functions/

Today, AWS Identity and Access Management (IAM) made 10 AWS managed policies available that align with common job functions in organizations. AWS managed policies enable you to set permissions using policies that AWS creates and manages, and with a single AWS managed policy for job functions, you can grant the permissions necessary for network or database administrators, for example.

You can attach multiple AWS managed policies to your users, roles, or groups if they span multiple job functions. As with all AWS managed policies, AWS will keep these policies up to date as we introduce new services or actions. You can use any AWS managed policy as a template or starting point for your own custom policy if the policy does not fully meet your needs (however, AWS will not automatically update any of your custom policies). In this blog post, I introduce the new AWS managed policies for job functions and show you how to use them to assign permissions.

The following table lists the new AWS managed policies for job functions and their descriptions.

 Job function Description
Administrator This policy grants full access to all AWS services.
Billing This policy grants permissions for billing and cost management. These permissions include viewing and modifying budgets and payment methods. An additional step is required to access the AWS Billing and Cost Management pages after assigning this policy.
Data Scientist This policy grants permissions for data analytics and analysis. Access to the following AWS services is a part of this policy: Amazon Elastic Map Reduce, Amazon Redshift, Amazon Kinesis, Amazon Machine Learning, Amazon Data Pipeline, Amazon S3, and Amazon Elastic File System. This policy additionally enables you to use optional IAM service roles to leverage features in other AWS services. To grant such access, you must create a role for each of these services.
Database Administrator This policy grants permissions to all AWS database services. Access to the following AWS services is a part of this policy: Amazon DynamoDB, Amazon ElastiCache, Amazon RDS, and Amazon Redshift. This policy additionally enables you to use optional IAM service roles to leverage features in other AWS services. To grant such access, you must create a role for each of these services.
Developer Power User This policy grants full access to all AWS services except for IAM.
Network Administrator This policy grants permissions required for setting up and configuring network resources. Access to the following AWS services is included in this policy: Amazon Route 53, Route 53 Domains, Amazon VPC, and AWS Direct Connect. This policy grants access to actions that require delegating permissions to CloudWatch Logs. This policy additionally enables you to use optional IAM service roles to leverage features in other AWS services. To grant such access, you must create a role for this service.
Security Auditor This policy grants permissions required for configuring security settings and for monitoring events and logs in the account.
Support User This policy grants permissions to troubleshoot and resolve issues in an AWS account. This policy also enables the user to contact AWS support to create and manage cases.
System Administrator This policy grants permissions needed to support system and development operations. Access to the following AWS services is included in this policy: AWS CloudTrail, Amazon CloudWatch, CodeCommit, CodeDeploy, AWS Config, AWS Directory Service, EC2, IAM, AWS KMS, Lambda, RDS, Route 53, S3, SES, SQS, AWS Trusted Advisor, and Amazon VPC. This policy grants access to actions that require delegating permissions to EC2, CloudWatch, Lambda, and RDS. This policy additionally enables you to use optional IAM service roles to leverage features in other AWS services. To grant such access, you must create a role for each of these services.
View Only User This policy grants permissions to view existing resources across all AWS services within an account.

Some of the policies in the preceding table enable you to take advantage of additional features that are optional. These policies grant access to iam:passrole, which passes a role to delegate permissions to an AWS service to carry out actions on your behalf.  For example, the Network Administrator policy passes a role to CloudWatch’s flow-logs-vpc so that a network administrator can log and capture IP traffic for all the Amazon VPCs they create. You must create IAM service roles to take advantage of the optional features. To follow security best practices, the policies already include permissions to pass the optional service roles with a naming convention. This  avoids escalating or granting unnecessary permissions if there are other service roles in the AWS account. If your users require the optional service roles, you must create a role that follows the naming conventions specified in the policy and then grant permissions to the role.

For example, your system administrator may want to run an application on an EC2 instance, which requires passing a role to Amazon EC2. The system administrator policy already has permissions to pass a role named ec2-sysadmin-*. When you create a role called ec2-sysadmin-example-application, for example, and assign the necessary permissions to the role, the role is passed automatically to the service and the system administrator can start using the features. The documentation summarizes each of the use cases for each job function that requires delegating permissions to another AWS service.

How to assign permissions by using an AWS managed policy for job functions

Let’s say that your company is new to AWS, and you have an employee, Alice, who is a database administrator. You want Alice to be able to use and manage all the database services while not giving her full administrative permissions. In this scenario, you can use the Database Administrator AWS managed policy. This policy grants view, read, write, and admin permissions for RDS, DynamoDB, Amazon Redshift, ElastiCache, and other AWS services a database administrator might need.

The Database Administrator policy passes several roles for various use cases. The following policy shows the different service roles that are applicable to a database administrator.

{
            "Effect": "Allow",
            "Action": [
                "iam:GetRole",
                "iam:PassRole"
            ],
            "Resource": [
                "arn:aws:iam::*:role/rds-monitoring-role",
                "arn:aws:iam::*:role/rdbms-lambda-access",
                "arn:aws:iam::*:role/lambda_exec_role",
                "arn:aws:iam::*:role/lambda-dynamodb-*",
                "arn:aws:iam::*:role/lambda-vpc-execution-role",
                "arn:aws:iam::*:role/DataPipelineDefaultRole",
                "arn:aws:iam::*:role/DataPipelineDefaultResourceRole"
            ]
        }

However, in order for user Alice to be able to leverage any of the features that require another service, you must create a service role and grant it permissions. In this scenario, Alice wants only to monitor RDS databases. To enable Alice to monitor RDS databases, you must create a role called rds-monitoring-role and assign the necessary permissions to the role.

Steps to assign permissions to the Database Administrator policy in the IAM console

  1. Sign in to the IAM console.
  2. In the left pane, choose Policies and type database in the Filter box.
    Screenshot of typing "database" in filter box
  1. Choose the Database Administrator policy, and then choose Attach in the Policy Actions drop-down menu.
    Screenshot of choosing "Attach" from drop-down list
  1. Choose the user (in this case, I choose Alice), and then choose Attach Policy.
    Screenshot of selecting the user
  2. User Alice now has Database Administrator permissions. However, for Alice to monitor RDS databases, you must create a role called rds-monitoring-role. To do this, in the left pane, choose Roles, and then choose Create New Role.
  3. For the Role Name, type rds-monitoring-role to match the name that is specified in the Database Administrator. Choose Next Step.
    Screenshot of creating the role called rds-monitoring-role
  1. In the AWS Service Roles section, scroll down and choose Amazon RDS Role for Enhanced Monitoring.
    Screenshot of selecting "Amazon RDS Role for Enhanced Monitoring"
  1. Choose the AmazonRDSEnhancedMonitoringRole policy and then choose Select.
    Screenshot of choosing AmazonRDSEnhancedMonitoringRole
  2. After reviewing the role details, choose Create Role.

User Alice now has Database Administrator permissions and can now monitor RDS databases. To use other roles for the Database Administrator AWS managed policy, see the documentation.

Now Open – AWS US East (Ohio) Region

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/now-open-aws-us-east-ohio-region/

As part of our ongoing plan to expand the AWS footprint, I am happy to announce that our new US East (Ohio) Region is now available. In conjunction with the existing US East (Northern Virginia) Region, AWS customers in the Eastern part of the United States have fast, low-latency access to the suite of AWS infrastructure services.

The Details
The new Ohio Region supports Amazon Elastic Compute Cloud (EC2) and related services including Amazon Elastic Block Store (EBS), Amazon Virtual Private Cloud, Auto Scaling, Elastic Load Balancing, NAT Gateway, Spot Instances, and Dedicated Hosts.

It also supports (deep breath) Amazon API Gateway, Amazon Aurora, AWS Certificate Manager (ACM), AWS CloudFormation, Amazon CloudFront, AWS CloudHSM, Amazon CloudWatch (including CloudWatch Events and CloudWatch Logs), AWS CloudTrail, AWS CodeCommit, AWS CodeDeploy, AWS CodePipeline, AWS Config, AWS Database Migration Service, AWS Direct Connect, Amazon DynamoDB, EC2 Container Registy, Amazon ECS, Amazon Elastic File System, Amazon ElastiCache, AWS Elastic Beanstalk, Amazon EMR, Amazon Elasticsearch Service, Amazon Glacier, AWS Identity and Access Management (IAM), AWS Import/Export Snowball, AWS Key Management Service (KMS), Amazon Kinesis, AWS Lambda, AWS Marketplace, Mobile Hub, AWS OpsWorks, Amazon Relational Database Service (RDS), Amazon Redshift, Amazon Route 53, Amazon Simple Storage Service (S3), AWS Service Catalog, Amazon Simple Notification Service (SNS), Amazon Simple Queue Service (SQS), AWS Storage Gateway, Amazon Simple Workflow Service (SWF), AWS Trusted Advisor, VM Import/Export, and AWS WAF.

The Region supports all sizes of C4, D2, I2, M4, R3, T2, and X1 instances. As is the case with all of our newer Regions, instances must be launched within a Virtual Private Cloud (read Virtual Private Clouds for Everyone to learn more).

Well Connected
Here are some round-trip network metrics that you may find interesting (all names are airport codes, as is apparently customary in the networking world; all times are +/- 2 ms):

  • 12 ms to IAD (home of the US East (Northern Virginia) Region).
  • 20 ms to JFK (home to an Internet exchange point).
  • 29 ms to ORD (home to a pair of Direct Connect locations hosted by QTS and Equinix and another exchange point).
  • 91 ms to SFO (home of the US West (Northern California) Region).

With just 12 ms of round-trip latency between US East (Ohio) and US East (Northern Virginia), you can make good use of unique AWS features such as S3 Cross-Region Replication, Cross-Region Read Replicas for Amazon Aurora, Cross-Region Read Replicas for MySQL, and Cross-Region Read Replicas for PostgreSQL. Data transfer between the two Regions is priced at the Inter-AZ price ($0.01 per GB), making your cross-region use cases even more economical.

Also on the networking front, we have agreed to work together with Ohio State University to provide AWS Direct Connect access to OARnet. This 100-gigabit network connects colleges, schools, medical research hospitals, and state government across Ohio. This connection provides local teachers, students, and researchers with a dedicated, high-speed network connection to AWS.

14 Regions, 38 Availability Zones, and Counting
Today’s launch of this 3-AZ Region expands our global footprint to a grand total of 14 Regions and 38 Availability Zones. We are also getting ready to open up a second AWS Region in China, along with other new AWS Regions in Canada, France, and the UK.

Since there’s been some industry-wide confusion about the difference between Regions and Availability Zones of late, I think it is important to understand the differences between these two terms. Each Region is a physical location where we have one or more Availability Zones or AZs. Each Availability Zone, in turn, consists of one or more data centers, each with redundant power, networking, and connectivity, all housed in separate facilities. Having two or more AZ’s in each Region gives you the ability to run applications that are more highly available, fault tolerant, and durable than would be the case if you were limited to a single AZ.

Around the office, we sometimes play with analogies that can serve to explain the difference between the two terms. My favorites are “Hotels vs. hotel rooms” and “Apple trees vs. apples.” So, pick your analogy, but be sure that you know what it means!

New AWS Quick Starts for Atlassian JIRA Software and Bitbucket Data Center

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/new-aws-quick-starts-for-atlassian-jira-software-and-bitbucket-data-center/

The AWS Quick Starts help you to rapidly deploy reference implementations of software solutions on the AWS Cloud. You can use the Quick Starts to easily test drive and consume software while taking advantage of best practices promoted by AWS and the software partner.

Today I would like to tell you about a pair of Quick Start guides that were developed in collaboration with APN Advanced Technology Partner (and DevOps competency holder) Atlassian to help you to deploy their JIRA Software Data Center and Bitbucket Data Center on AWS.

Atlassian’s Data Center offerings are designed for customers that have large development teams and a need for scalable, highly available development and project management tools. Because these tools are invariably mission-critical, robustness and resilience are baseline requirements, production deployments are always run in a multi-node or cluster configuration.

New Quick Starts
JIRA Software Data Center is a project and issue management solution for agile teams and Bitbucket Data Center is a Git repository solution, both of which provide large teams working on multiple projects with high availability and performance at scale. With these two newly introduced Atlassian Quick Starts, you have access to a thoroughly tested, fully supported reference architecture that greatly simplifies and accelerates the deployment of these products on AWS.

The Quick Starts include AWS CloudFormation templates that allow you deploy Bitbucket and/or JIRA Software into a new or existing Virtual Private Cloud (VPC). If you want to use a new VPC, the template will create it, along with public and private subnets and a NAT Gateway to allow EC2 instances in the private subnet to connect to the Internet (in regions where the NAT Gateway is not available, the template will create a NAT instance instead). If you are already using AWS and have a suitable VPC, you can deploy JIRA Software Data Center and Bitbucket Data Center there instead.

You will need to sign up for evaluation licenses for the Atlassian products that you intend to launch.

Bitbucket Data Center
The Bitbucket Data Center Quick Start deploys the following components as part of the deployment:

Amazon RDS PostgreSQL – Bitbucket Data Center requires a supported external database. Amazon RDS for PostgreSQL in a Multi-AZ configuration allows failover in the event the master node fails.

NFS Server –  Bitbucket Data Center uses a shared file system to store the repositories in a common location that is accessible to multiple Bitbucket nodes. The Quick Start architecture implements the shared file system in an EC2 instance with an attached Amazon Elastic Block Store (EBS) volume.

Bitbucket Auto Scaling Group – The Bitbucket Data Center product is installed on Amazon Elastic Compute Cloud (EC2) instances in an Auto Scaling group. The deployment will scale out and in, based on utilization.

Amazon Elasticsearch Service – Bitbucket Data Center uses Elasticsearch for indexing and searching.  The Quick Start architecture uses Amazon Elasticsearch Service, a managed service that makes it easy to deploy, operate, and scale Elasticsearch in the AWS Cloud.

JIRA Software Data Center
The JIRA Software Data Center Quick Start deploys the following components as part of the deployment:

Amazon RDS PostgreSQL – JIRA Data Center requires a supported external database. Amazon RDS for PostgreSQL in a Multi-AZ configuration allows failover in the event the master node fails.

Amazon Elastic File System – JIRA Software Data Center uses a shared file system to store artifacts in a common location that is accessible to multiple JIRA nodes. The Quick Start architecture implements a highly available shared file system using Amazon Elastic File System.

JIRA Auto Scaling Group – The JIRA Data Center product is installed on Amazon Elastic Compute Cloud (EC2) instances in an Auto Scaling group. The deployment will scale out and in, based on utilization.

We will continue to work with Atlassian to update and refine these two new Quick Starts.  We’re also working on two additional Quick Starts for Atlassian Confluence and Atlassian JIRA Service Desk and hope to have them ready before AWS re:Invent.

To get started, please visit the Bitbucket Data Center Quick Start or the JIRA Software Data Center Quick Start. You can also head over to Atlassian’s Quick Start page. The templates are available today; give them a whirl and let us know what you think!

Amazon Elastic File System – Production-Ready in Three Regions

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/amazon-elastic-file-system-production-ready-in-three-regions/

The portfolio of AWS storage products has grown increasingly rich and diverse over time. Amazon S3 started out with a single storage class and has grown to include storage classes for regular, infrequently accessed, and archived objects. Similarly, Amazon Elastic Block Store (EBS) began with a single volume type and now offers a choice of four types of SAN-style block storage, each designed to be a great for a particular set of access patterns and data types.

With object storage and block storage capably addressed by S3 and EBS, we turned our attention to the file system. We announced the Amazon Elastic File System (EFS) last year in order to provide multiple EC2 instances with shared, low-latency access to a fully-managed file system.

I am happy to announce that EFS is now available for production use in the US East (Northern Virginia), US West (Oregon), and Europe (Ireland) Regions.

We are launching today after an extended preview period that gave us insights into an extraordinarily wide range of customer use cases. The EFS preview was a great fit for large-scale, throughput-heavy processing workloads, along with many forms of content and web serving. During the preview we received a lot of positive feedback about the performance of EFS for these workloads, along with requests to provide equally good support for workloads that are sensitive to latency and/or make heavy use of file system metadata. We’ve been working to address this feedback and today’s launch is designed to handle a very wide range of use cases. Based on what I have heard so far, our customers are really excited about EFS and plan to put it to use right away.

Why We Built EFS
Many AWS customers have asked us for a way to more easily manage file storage on a scalable basis. Some of these customers run farms of web servers or content management systems that benefit from a common namespace and easy access to a corporate or departmental file hierarchy. Others run HPC and Big Data applications that create, process, and then delete many large files, resulting in storage utilization and throughput demands that vary wildly over time. Our customers also insisted on high availability, and durability, along with a strongly consistent model for access and modification.

Amazon Elastic File System
EFS lets you create POSIX-compliant file systems and attach them to one or more of your EC2 instances via NFS. The file system grows and shrinks as necessary (there’s no fixed upper limit and you can grow to petabyte scale) and you don’t pre-provision storage space or bandwidth. You pay only for the storage that you use.

EFS protects your data by storing copies of your files, directories, links, and metadata in multiple Availability Zones.

In order to provide the performance needed to support large file systems accessed by multiple clients simultaneously, Elastic File System performance scales with storage (I’ll say more about this later).

Each Elastic File System is accessible from a single VPC, and is accessed by way of mount targets that you create within the VPC. You have the option to create a mount target in any desired subnet of your VPC. Access to each mount target is controlled, as usual, via Security Groups.

EFS offers two distinct performance modes. The first mode, General Purpose, is the default. You should use this mode unless you expect to have tens, hundreds, or thousands of EC2 instances access the file system concurrently. The second mode, Max I/O, is optimized for higher levels of aggregate throughput and operations per second, but incurs slightly higher latencies for file operations. In most cases, you should start with general purpose mode and watch the relevant CloudWatch metric (PercentIOLimit). When you begin to push the I/O limit of General Purpose mode, you can create a new file system in Max I/O mode, migrate your files, and enjoy even higher throughput and operations per second.

Elastic File System in Action
It is very easy to create, mount, and access an Elastic File System. I used the AWS Management Console; I could have used the EFS API, the AWS Command Line Interface (CLI), or the AWS Tools for Windows PowerShell as well.

I opened the console and clicked on the Create file system button:

Then I selected one of my VPCs and created a mount target in my public subnet:

My security group (corp-vpc-mount-target) allows my EC2 instance to access the mount point on port 2049. Here’s the inbound rule; the outbound one is the same:

I added Name and Owner tags, and opted for the General Purpose performance mode:

Then I confirmed the information and clicked on Create File System:

My file system was ready right away (the mount targets took another minute or so):

I clicked on EC2 mount instructions to learn how to mount my file system on an EC2 instance:

I mounted my file system as /efs, and there it was:

I copied a bunch of files over, and spent some time watching the NFS stats:

The console reports on the amount of space consumed by my file systems (this information is collected every hour and is displayed 2-3 hours after it is collected):

CloudWatch Metrics
Each file system delivers the following metrics to CloudWatch:

  • BurstCreditBalance – The amount of data that can be transferred at the burst level of throughput.
  • ClientConnections – The number of clients that are connected to the file system.
  • DataReadIOBytes – The number of bytes read from the file system.
  • DataWriteIOBytes -The number of bytes written to the file system.
  • MetadataIOBytes – The number of bytes of metadata read and written.
  • TotalIOBytes -The sum of the preceding three metrics.
  • PermittedThroughput -The maximum allowed throughput, based on file system size.
  • PercentIOLimit – The percentage of the available I/O utilized in General Purpose mode.

You can see the metrics in the CloudWatch Console:

EFS Bursting, Workloads, and Performance
The throughput available to each of your EFS file systems will grow as the file system grows. Because file-based workloads are generally spiky, with demands for high levels of throughput for short amounts of time and low levels the rest of the time, EFS is designed to burst to high throughput levels on an as-needed basis.

All file systems can burst to 100 MB per second of throughput. Those over 1 TB can burst to an additional 100 MB per second for each TB stored. For example, a 2 TB file system can burst to 200 MB per second and a 10 TB file system can burst to 1,000 MB per second of throughput. File systems larger than 1 TB can always burst for 50% of the time if they are inactive for the other 50%.

EFS uses a credit system to determine when a file system can burst. Each one accumulates credits at a baseline rate (50 MB per TB of storage) that is determined by the size of the file system, and spends them whenever it reads or writes data. The accumulated credits give the file system the ability to drive throughput beyond the baseline rate.

Here are some examples to give you a better idea of what this means in practice:

  • A 100 GB file system can burst up to 100 MB per second for up to 72 minutes each day, or drive up to 5 MB per second continuously.
  • A 10 TB file system can burst up to 1 GB per second for 12 hours each day, or drive 500 MB per second continuously.

To learn more about how the credit system works, read about File System Performance in the EFS documentation.

In order to gain a better understanding of this feature, I spent a couple of days copying and concatenating files, ultimately ending up using well over 2 TB of space on my file system. I watched the PermittedThroughput metric grow in concert with my usage as soon as my file collection exceeed 1 TB. Here’s what I saw:

As is the case with any file system, the throughput you’ll see is dependent on the characteristics of your workload. The average I/O size, the number of simultaneous connections to EFS, the file access pattern (random or sequential), the request model (synchronous or asynchronous), the NFS client configuration, and the performance characteristics of the EC2 instances running the NFS clients each have an effect (positive or negative). Briefly:

  • Average I/O Size – The work associated with managing the metadata associated with small files via the NFS protocol, coupled with the work that EFS does to make your data highly durable and highly available, combine to create some per-operation overhead. In general, overall throughput will increase in concert with the average I/O size since the per-operation overhead is amortized over a larger amount of data. Also, reads will generally be faster than writes.
  • Simultaneous Connections – Each EFS file system can accommodate connections from thousands of clients. Environments that can drive highly parallel behavior (from multiple EC2 instances) will benefit from the ability that EFS has to support a multitude of concurrent operations.
  • Request Model – If you enable asynchronous writes to the file system by including the async option at mount time, pending writes will be buffered on the instance and then written to EFS asynchronously. Accessing a file system that has been mounted with the sync option or opening files using an option that bypasses the cache (e.g. O_DIRECT) will, in turn, issue synchronous requests to EFS.
  • NFS Client Configuration – Some NFS clients use laughably small (by today’s standards) values for the read and write buffers by default. Consider increasing it to 1 MiB (again, this is an option to the mount command). You can use an NFS 4.0 or 4.1 client with EFS; the latter will provide better performance.
  • EC2 Instances – Applications that perform large amounts of I/O sometimes require a large amount of memory and/or compute power as well. Be sure that you have plenty of both; choose an appropriate instance size and type. If you are performing asynchronous reads and writes, the kernel use additional memory for caching. As a side note, the performance characteristics of EFS file systems are not dependent on the use of EBS-optimized instances.

Benchmarking of file systems is a blend of art and science. Make sure that you use mature, reputable tools, run them more than once, and make sure that you examine your results in light of the considerations listed above. You can also find some detailed data regarding expected performance on the Amazon Elastic File System page.

Available Now
EFS is available now in the US East (Northern Virginia), US West (Oregon), and Europe (Ireland) Regions and you can start using it today.  Pricing is based on the amount of data that you store, sampled several times per day and charged by the Gigabyte-month, pro-rated as usual, starting at $0.30 per GB per month in the US East (Northern Virginia) Region. There are no minimum fees and no setup costs (see the EFS Pricing page for more information). If you are eligible for the AWS Free Tier, you can use up to 5 GB of EFS storage per month at no charge.
