ICYMI: Serverless Q2 2022

Welcome to the 18th 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 Node.js developers, AWS Lambda now supports the Node.js 16.x runtime version. This offers new features, including the Stable timers promises API and RegExp match indices. There is also new documentation for TypeScript with Lambda.

Customers are rapidly adopting the new runtime version by updating to Node.js 16.x. To help keep Lambda functions secure, AWS continually updates Node.js 16 with all minor updates released by the Node.js community when using the zip archive format. Read the release blog post to learn more about building Lambda functions with Node.js 16.x.

A new Lambda custom runtime is now available for PowerShell. It makes it even easier to run Lambda functions written in PowerShell. Although Lambda has supported PowerShell since 2018, this new version simplifies the process and reduces the additional steps required during the development process.

To get started, see the GitHub repository which contains the code, examples and installation instructions.

AWS Lambda Powertools is an open-source library to help customers discover and incorporate serverless best practices more easily. Powertools for Python went GA in July 2020, followed by Java in 2021, TypeScript in 2022, and .NET is coming soon. AWS Lambda Powertools crossed the 10M download milestone and TypeScript support has now moved from beta to a release candidate.

When building with Lambda, it’s important to develop solutions to handle retries and failures when the same event may be received more than once. Lambda Powertools provide a utility to handle idempotency within your functions.

AWS Step Functions

AWS Step Functions launched a new opt-in console experience to help builders analyze, debug, and optimize Step Functions Standard Workflows. This allows you to debug workflow executions and analyze the payload as it passes through each state. To opt in to the new console experience and get started, follow these detailed instructions.

Amazon EventBridge

Amazon EventBridge released support for global endpoints in April 2022. Global endpoints provide a reliable way for you to improve availability and reliability of event-driven applications. Using global endpoints, you can fail over event ingestion automatically to another Region during service disruptions.

The new IngestionToInvocationStartLatency metric exposes the time to process events from the point at which they are ingested by EventBridge to the point of the first invocation. Amazon Route 53 uses this information to failover event ingestion automatically to a secondary Region if the metric exceeds a configured threshold of 30 seconds, consecutively for 5 minutes.

Serverlesspresso goes global

Serverlesspresso in five countries

Serverlesspresso is a serverless event-driven application that allows you to order coffee from your phone.

Since building Serverlesspresso for reinvent 2021, the Developer Advocate team have put in approximately 100 additional development hours to improve the application to make it a multi-tenant event-driven serverless app.

This allowed us to run Serverlesspresso concurrently at five separate events across Europe on a single day in June, serving over 5,000 coffees. Each order is orchestrated by a single Step Functions workflow. To read more about how this application is built:

The AWS Heroes program recognizes talented experts whose enthusiasm for knowledge-sharing has a real impact within the community. The EMEA-based Heroes gathered for a Summit on June 28 to share their thoughts, providing valuable feedback on topics such as containers, serverless and machine learning.

Serverless workflow collection added to Serverless Land

Serverless Land is a website that is maintained by the Serverless Developer Advocate team to help you learn with workshops, patterns, blogs and videos.

The Developer Advocate team have extended Serverless Land and introduced the new AWS Step Functions workflows collection.

Using the new collection you can explore common patterns built with Step Functions and use the 1-click deploy button to deploy straight into your AWS account.
