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.
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 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.
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. Visit this link if you are ready to get started learning or just jump directly to the assessment.

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:
- Building Serverlesspresso: Creating event-driven architectures (SVS312)
- Advanced serverless workflow patterns and best practices (API309)
- Building next-gen applications with event-driven architectures (API311-R)
- Building global event-driven applications (API302-R)
- Best practices for advanced serverless developers (SVS401)
- Lift and shift a web application to serverless: Yes, it’s possible! (BOA326)
- Building observable applications with OpenTelemetry (BOA310)
- Building real-world serverless applications with AWS SAM (SVS303)
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.
