Serverless ICYMI Q4 2022

Post Syndicated from Marcia Villalba original https://aws.amazon.com/blogs/compute/serverless-icymi-q4-2022/

Welcome to the 20th edition of the AWS Serverless ICYMI (in case you missed it) quarterly recap. Every quarter, we share all the most recent product launches, feature enhancements, blog posts, webinars, Twitch live streams, and other interesting things that you might have missed!In case you missed our last ICYMI, check out what happened last quarter here.

AWS Lambda

For developers using Java, AWS Lambda has introduced Lambda SnapStart. SnapStart is a new capability that can improve the start-up performance of functions using Corretto (java11) runtime by up to 10 times, at no extra cost.

To use this capability, you must enable it in your function and then publish a new version. This triggers the optimization process. This process initializes the function, takes an immutable, encrypted snapshot of the memory and disk state, and caches it for reuse. When the function is invoked, the state is retrieved from the cache in chunks, on an as-needed basis, and it is used to populate the execution environment.

The ICYMI: Serverless pre:Invent 2022 post shares some of the launches for Lambda before November 21, like the support of Lambda functions using Node.js 18 as a runtime, the Lambda Telemetry API, and new .NET tooling to support .NET 7 applications.

Also, now Amazon Inspector supports Lambda functions. You can enable Amazon Inspector to scan your functions continually for known vulnerabilities. The log4j vulnerability shows how important it is to scan your code for vulnerabilities continuously, not only after deployment. Vulnerabilities can be discovered at any time, and with Amazon Inspector, your functions and layers are rescanned whenever a new vulnerability is published.

AWS Step Functions

There were many new launches for AWS Step Functions, like intrinsic functions, cross-account access capabilities, and the new executions experience for Express Workflows covered in the pre:Invent post.

During AWS re:Invent this year, we announced Step Functions Distributed Map. If you need to process many files, or items inside CSV or JSON files, this new flow can help you. The new distributed map flow orchestrates large-scale parallel workloads.

This feature is optimized for files stored in Amazon S3. You can either process in parallel multiple files stored in a bucket, or process one large JSON or CSV file, in which each line contains an independent item. For example, you can convert a video file into multiple .gif animations using a distributed map, or process over 37 GB of aggregated weather data to find the highest temperature of the day. 

Amazon EventBridge

Amazon EventBridge launched two major features: Scheduler and Pipes. Amazon EventBridge Scheduler allows you to create, run, and manage scheduled tasks at scale. You can schedule one-time or recurring tasks across 270 services and over 6.000 APIs.

Amazon EventBridge Pipes allows you to create point-to-point integrations between event producers and consumers. With Pipes you can now connect different sources, like Amazon Kinesis Data Streams, Amazon DynamoDB Streams, Amazon SQS, Amazon Managed Streaming for Apache Kafka, and Amazon MQ to over 14 targets, such as Step Functions, Kinesis Data Streams, Lambda, and others. It not only allows you to connect these different event producers to consumers, but also provides filtering and enriching capabilities for events.

EventBridge now supports enhanced filtering capabilities including:

  • Matching against characters at the end of a value (suffix filtering)
  • Ignoring case sensitivity (equals-ignore-case)
  • OR matching: A single rule can match if any conditions across multiple separate fields are true.

It’s now also simpler to build rules, and you can generate AWS CloudFormation from the console pages and generate event patterns from a schema.

AWS Serverless Application Model (AWS SAM)

There were many announcements for AWS SAM during this quarter summarized in the ICMYI: Serverless pre:Invent 2022 post, like AWS SAM Connectors, SAM CLI Pipelines now support OpenID Connect Protocol, and AWS SAM CLI Terraform support.

AWS Application Composer

AWS Application Composer is a new visual designer that you can use to build serverless applications using multiple AWS services. This is ideal if you want to build a prototype, review with others architectures, generate diagrams for your projects, or onboard new team members to a project.

Within a simple user interface, you can drag and drop the different AWS resources and configure them visually. You can use AWS Application Composer together with AWS SAM Accelerate to build and test your applications in the AWS Cloud.

AWS Serverless digital learning badges

The new AWS Serverless digital learning badges let you show your AWS Serverless knowledge and skills. This is a verifiable digital badge that is aligned with the AWS Serverless Learning Plan.

This badge proves your knowledge and skills for Lambda, Amazon API Gateway, and designing serverless applications. To earn this badge, you must score at least 80 percent on the assessment associated with the Learning Plan.

AWS re:Invent 2022

AWS re:Invent was held in Las Vegas from November 28 to December 2, 2022. Werner Vogels, Amazon’s CTO, highlighted event-driven applications during his keynote. He stated that the world is asynchronous and showed how strange a synchronous world would be. During the keynote, he showcased Serverlesspresso as an example of an event-driven application. The Serverless DA team presented many breakouts, workshops, and chalk talks. Rewatch all our breakout content:

In addition, we brought Serverlesspresso back to Vegas. Serverlesspresso is a contactless, serverless order management system for a physical coffee bar. The architecture comprises several serverless apps that support an ordering process from a customer’s smartphone to a real espresso bar. The customer can check the virtual line, place an order, and receive a notification when their drink is ready for pickup.

ICYMI: Serverless Q4 2020

Post Syndicated from James Beswick original https://aws.amazon.com/blogs/compute/icymi-serverless-q4-2020/

Welcome to the 12th edition of the AWS Serverless ICYMI (in case you missed it) quarterly recap. Every quarter, we share all of the most recent product launches, feature enhancements, blog posts, webinars, Twitch live streams, and other interesting things that you might have missed!

ICYMI Q4 calendar

In case you missed our last ICYMI, check out what happened last quarter here.

AWS re:Invent

re:Invent 2020 banner

re:Invent was entirely virtual in 2020 and free to all attendees. The conference had a record number of registrants and featured over 700 sessions. The serverless developer advocacy team presented a number of talks to help developers build their skills. These are now available on-demand:

AWS Lambda

There were three major Lambda announcements at re:Invent. Lambda duration billing changed granularity from 100 ms to 1 ms, which is shown in the December billing statement. All functions benefit from this change automatically, and it’s especially beneficial for sub-100ms Lambda functions.

Lambda has also increased the maximum memory available to 10 GB. Since memory also controls CPU allocation in Lambda, this means that functions now have up to 6 vCPU cores available for processing. Finally, Lambda now supports container images as a packaging format, enabling teams to use familiar container tooling, such as Docker CLI. Container images are stored in Amazon ECR.

There were three feature releases that make it easier for developers working on data processing workloads. Lambda now supports self-hosted Kafka as an event source, allowing you to source events from on-premises or instance-based Kafka clusters. You can also process streaming analytics with tumbling windows and use custom checkpoints for processing batches with failed messages.

We launched Lambda Extensions in preview, enabling you to more easily integrate monitoring, security, and governance tools into Lambda functions. You can also build your own extensions that run code during Lambda lifecycle events. See this example extensions repo for starting development.

You can now send logs from Lambda functions to custom destinations by using Lambda Extensions and the new Lambda Logs API. Previously, you could only forward logs after they were written to Amazon CloudWatch Logs. Now, logging tools can receive log streams directly from the Lambda execution environment. This makes it easier to use your preferred tools for log management and analysis, including Datadog, Lumigo, New Relic, Coralogix, Honeycomb, or Sumo Logic.

Lambda Logs API architecture

Lambda launched support for Amazon MQ as an event source. Amazon MQ is a managed broker service for Apache ActiveMQ that simplifies deploying and scaling queues. The event source operates in a similar way to using Amazon SQS or Amazon Kinesis. In all cases, the Lambda service manages an internal poller to invoke the target Lambda function.

Lambda announced support for AWS PrivateLink. This allows you to invoke Lambda functions from a VPC without traversing the public internet. It provides private connectivity between your VPCs and AWS services. By using VPC endpoints to access the Lambda API from your VPC, this can replace the need for an Internet Gateway or NAT Gateway.

For developers building machine learning inferencing, media processing, high performance computing (HPC), scientific simulations, and financial modeling in Lambda, you can now use AVX2 support to help reduce duration and lower cost. In this blog post’s example, enabling AVX2 for an image-processing function increased performance by 32-43%.

Lambda now supports batch windows of up to 5 minutes when using SQS as an event source. This is useful for workloads that are not time-sensitive, allowing developers to reduce the number of Lambda invocations from queues. Additionally, the batch size has been increased from 10 to 10,000. This is now the same batch size as Kinesis as an event source, helping Lambda-based applications process more data per invocation.

Code signing is now available for Lambda, using AWS Signer. This allows account administrators to ensure that Lambda functions only accept signed code for deployment. You can learn more about using this new feature in the developer documentation.

AWS Step Functions

Synchronous Express Workflows have been launched for AWS Step Functions, providing a new way to run high-throughput Express Workflows. This feature allows developers to receive workflow responses without needing to poll services or build custom solutions. This is useful for high-volume microservice orchestration and fast compute tasks communicating via HTTPS.

The Step Functions service recently added support for other AWS services in workflows. You can now integrate API Gateway REST and HTTP APIs. This enables you to call API Gateway directly from a state machine as an asynchronous service integration.

Step Functions now also supports Amazon EKS service integration. This allows you to build workflows with steps that synchronously launch tasks in EKS and wait for a response. The service also announced support for Amazon Athena, so workflows can now query data in your S3 data lakes.

Amazon API Gateway

API Gateway now supports mutual TLS authentication, which is commonly used for business-to-business applications and standards such as Open Banking. This is provided at no additional cost. You can now also disable the default REST API endpoint when deploying APIs using custom domain names.

HTTP APIs now supports service integrations with Step Functions Synchronous Express Workflows. This is a result of the service team’s work to add the most popular features of REST APIs to HTTP APIs.

AWS X-Ray

X-Ray now integrates with Amazon S3 to trace upstream requests. If a Lambda function uses the X-Ray SDK, S3 sends tracing headers to downstream event subscribers. This allows you to use the X-Ray service map to view connections between S3 and other services used to process an application request.

X-Ray announced support for end-to-end tracing in Step Functions to make it easier to trace requests across multiple AWS services. It also launched X-Ray Insights in preview, which generates actionable insights based on anomalies detected in an application. For Java developers, the services released an auto-instrumentation agent, for collecting instrumentation without modifying existing code.

Additionally, the AWS Distro for Open Telemetry is now in preview. OpenTelemetry is a collaborative effort by tracing solution providers to create common approaches to instrumentation.

Amazon EventBridge

You can now use event replay to archive and replay events with Amazon EventBridge. After configuring an archive, EventBridge automatically stores all events or filtered events, based upon event pattern matching logic. Event replay can help with testing new features or changes in your code, or hydrating development or test environments.

EventBridge archive and replay

EventBridge also launched resource policies that simplify managing access to events across multiple AWS accounts. Resource policies provide a powerful mechanism for modeling event buses across multiple account and providing fine-grained access control to EventBridge API actions.

EventBridge resource policies

EventBridge announced support for Server-Side Encryption (SSE). Events are encrypted using AES-256 at no additional cost for customers. EventBridge also increased PutEvent quotas to 10,000 transactions per second in US East (N. Virginia), US West (Oregon), and Europe (Ireland). This helps support workloads with high throughput.

Developer tools

The AWS SDK for JavaScript v3 was launched and includes first-class TypeScript support and a modular architecture. This makes it easier to import only the services needed to minimize deployment package sizes.

The AWS Serverless Application Model (AWS SAM) is an AWS CloudFormation extension that makes it easier to build, manage, and maintain serverless applications. The latest versions include support for cached and parallel builds, together with container image support for Lambda functions.

You can use AWS SAM in the new AWS CloudShell, which provides a browser-based shell in the AWS Management Console. This can help run a subset of AWS SAM CLI commands as an alternative to using a dedicated instance or AWS Cloud9 terminal.

AWS CloudShell

Amazon SNS

Amazon SNS announced support for First-In-First-Out (FIFO) topics. These are used with SQS FIFO queues for applications that require strict message ordering with exactly once processing and message deduplication.

Amazon DynamoDB

Developers can now use PartiQL, an SQL-compatible query language, with DynamoDB tables, bringing familiar SQL syntax to NoSQL data. You can also choose to use Kinesis Data Streams to capture changes to tables.

For customers using DynamoDB global tables, you can now use your own encryption keys. While all data in DynamoDB is encrypted by default, this feature enables you to use customer managed keys (CMKs). DynamoDB also announced the ability to export table data to data lakes in Amazon S3. This enables you to use services like Amazon Athena and AWS Lake Formation to analyze DynamoDB data with no custom code required.

AWS Amplify and AWS AppSync

You can now use existing Amazon Cognito user pools and identity pools for Amplify projects, making it easier to build new applications for an existing user base. With the new AWS Amplify Admin UI, you can configure application backends without using the AWS Management Console.

AWS AppSync enabled AWS WAF integration, making it easier to protect GraphQL APIs against common web exploits. You can also implement rate-based rules to help slow down brute force attacks. Using AWS Managed Rules for AWS WAF provides a faster way to configure application protection without creating the rules directly.

ICYMI: Serverless Q3 2020

Post Syndicated from James Beswick original https://aws.amazon.com/blogs/compute/icymi-serverless-q3-2020/

Welcome to the 11th edition of the AWS Serverless ICYMI (in case you missed it) quarterly recap. Every quarter, we share all of the most recent product launches, feature enhancements, blog posts, webinars, Twitch live streams, and other interesting things that you might have missed!

Q3 Calendar

In case you missed our last ICYMI, checkout what happened last quarter here.

AWS Lambda

MSK trigger in Lambda

In August, we launched support for using Amazon Managed Streaming for Apache Kafka (Amazon MSK) as an event source for Lambda functions. Lambda has existing support for processing streams from Kinesis and DynamoDB. Now you can process data streams from Amazon MSK and easily integrate with downstream serverless workflows. This integration allows you to process batches of records, one per partition at a time, and scale concurrency by increasing the number of partitions in a topic.

We also announced support for Java 8 (Corretto) in Lambda, and you can now use Amazon Linux 2 for custom runtimes. Amazon Linux 2 is the latest generation of Amazon Linux and provides an application environment with access to the latest innovations in the Linux ecosystem.

Amazon API Gateway

API integrations

API Gateway continued to launch new features for HTTP APIs, including new integrations for five AWS services. HTTP APIs can now route requests to AWS AppConfig, Amazon EventBridge, Amazon Kinesis Data Streams, Amazon SQS, and AWS Step Functions. This makes it easy to create webhooks for business logic hosted in these services. The service also expanded the authorization capabilities, adding Lambda and IAM authorizers, and enabled wildcards in custom domain names. Over time, we will continue to improve and migrate features from REST APIs to HTTP APIs.

In September, we launched mutual TLS for both regional REST APIs and HTTP APIs. This is a new method for client-to-server authentication to enhance the security of your API. It can protect your data from exploits such as client spoofing or man-in-the-middle. This enforces two-way TLS (or mTLS) which enables certificate-based authentication both ways from client-to-server and server-to-client.

Enhanced observability variables now make it easier to troubleshoot each phase of an API request. Each phase from AWS WAF through to integration adds latency to a request, returns a status code, or raises an error. Developers can use these variables to identify the cause of latency within the API request. You can configure these variables in AWS SAM templates – see the demo application to see how you can use these variables in your own application.

AWS Step Functions

X-Ray tracing in Step Functions

We added X-Ray tracing support for Step Functions workflows, giving you full visibility across state machine executions, making it easier to analyze and debug distributed applications. Using the service map view, you can visually identify errors in resources and view error rates across workflow executions. You can then drill into the root cause of an error. You can enable X-Ray in existing workflows by a single-click in the console. Additionally, you can now also visualize Step Functions workflows directly in the Lambda console. To see this new feature, open the Step Functions state machines page in the Lambda console.

Step Functions also increased the payload size to 256 KB and added support for string manipulation, new comparison operators, and improved output processing. These updates were made to the Amazon States Languages (ASL), which is a JSON-based language for defining state machines. The new operators include comparison operators, detecting the existence of a field, wildcarding, and comparing two input fields.

AWS Serverless Application Model (AWS SAM)

AWS SAM goes GA

AWS SAM is an open source framework for building serverless applications that converts a shorthand syntax into CloudFormation resources.

In July, the AWS SAM CLI became generally available (GA). This tool operates on SAM templates and provides developers with local tooling for building serverless applications. The AWS SAM CLI offers a rich set of tools that enable developers to build serverless applications quickly.

AWS X-Ray

X-Ray Insights

X-Ray launched a public preview of X-Ray Insights, which can help produce actionable insights for anomalies within your applications. Designed to make it easier to analyze and debug distributed applications, it can proactively identify issues caused by increases in faults. Using the incident timeline, you can visualize when the issue started and how it developed. The service identifies a probable root cause along with any anomalous services. There is no additional instrumentation needed to use X-Ray Insights – you can enable this feature within X-Ray Groups.

Amazon Kinesis

In July, Kinesis announced support for data delivery to generic HTTP endpoints, and service providers like Datadog, New Relic, MongoDB, and Splunk. Use the Amazon Kinesis console to configure your data producers to send data to Amazon Kinesis Data Firehose and specify one of these new delivery targets. Additionally, Amazon Kinesis Data Firehose is now available in the Europe (Milan) and Africa (Cape Town) AWS Regions.
