ICYMI: Serverless Q1 2022
Welcome to the 17th 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.
Lambda now offers larger ephemeral storage for functions, up to 10 GB. Previously, the storage was set to 512 MB. There are several common use-cases that can benefit from expanded temporary storage, including extract-transform load (ETL) jobs, machine learning inference, and data processing workloads. To see how to configure the amount of
/tmp storage in AWS SAM, deploy this Serverless Land Pattern.
For .NET developers, Lambda now supports .NET 6 as both a managed runtime and container base image. You can now use new features of the runtime such as improved logging, simplified function definitions using top-level statements, and improved performance using source generators.
The Lambda console now allows you to share test events with other developers in your team, using granular IAM permissions. Previously, test events were only visible to the builder who created them. To learn about creating sharable test events, read this documentation.
Amazon EventBridge Schema Registry helps you create code bindings from event schemas for use directly in your preferred IDE. You can generate these code bindings for a schema by using the EventBridge console, APIs, or AWS SDK toolkits for Jetbrains (Intellij, PyCharm, Webstorm, Rider) and VS Code. This feature now supports Go, in addition to Java, Python, and TypeScript, and is available at no additional cost.
AWS Step Functions
Developers can test state machines locally using Step Functions Local, and the service recently announced mocked service integrations for local testing. This allows you to define sample output from AWS service integrations and combine them into test cases to validate workflow control. This new feature introduces a robust way to state machines in isolation.
Amazon DynamoDB now supports limiting the number of items processed in PartiQL operation, using an optional parameter on each request. The service also increased default Service Quotas, which can help simplify the use of large numbers of tables. The per-account, per-Region quota increased from 256 to 2,500 tables.
AWS AppSync added support for custom response headers, allowing you to define additional headers to send to clients in response to an API call. You can now use the new resolver utility $util.http.addResponseHeaders() to configure additional headers in the response for a GraphQL API operation.
Serverless blog posts
Feb 10 – Introducing AWS Virtual Waiting Room
First anniversary of Serverless Land Patterns
The DA team launched the Serverless Patterns Collection in March 2021 as a repository of serverless examples that demonstrate integrating two or more AWS services. Each pattern uses an infrastructure as code (IaC) framework to automate the deployment. These can simplify the creation and configuration of the services used in your applications.
The Serverless Patterns Collection is both an educational resource to help developers understand how to join different services, and an aid for developers that are getting started with building serverless applications.
The collection has just celebrated its first anniversary. It now contains 239 patterns for CDK, AWS SAM, Serverless Framework, and Terraform, covering 30 AWS services. We have expanded example runtimes to include .NET, Java, Rust, Python, Node.js and TypeScript. We’ve served tens of thousands of developers in the first year and we’re just getting started.
Many thanks to our contributors and community. You can also contribute your own patterns.

AWS Global Summits are free events that bring the cloud computing community together to connect, collaborate, and learn about AWS. This year, we have restarted in-person Summits at major cities around the world.
The next 4 Summits planned are Paris (April 12), San Francisco (April 20-21), London (April 27), and Madrid (May 4-5). To find and register for your nearest AWS Summit, visit the AWS Summits homepage.
