Isn’t it amazing to debunk myths about Serverless while talking about how it performs in production and overcoming the hassles? This issue talks about several cases where we blame Serverless for not meeting our expectations but the reality is different, there are so many instances where Serverless has been a rescue for developers.

And we are also celebrating the new AWS Heroes of 2023.

📢 What's new in AWS Serverless

AWS Lambda Powertools for .NET is now generally available.

AWS Lambda now supports Amazon DocumentDB change streams as an event source.

AWS SAM CLI announces preview of Rust build support.

Code scans for Lambda functions within Amazon Inspector now in preview.

AWS Step Functions Distributed Map is now available in more Regions.

AWS Application Composer is now generally available.

Amazon DynamoDB now supports table deletion protection.

Use S3 Object Lambda with Amazon CloudFront to tailor content for end users.

🚀 AWSome content to learn from

An interesting read for front-end developers who are trying to integrate on AWS Amplify, Matteo Depascale walks through the different things which need to be considered for configuring Amplify authentication with SvelteKit.

Benjamen Pyle explains how filtering and enriching could be off-loaded to EventBridge Pipes while you focus on the business logic in his blog post Streaming AWS DynamoDB to a Lambda via EventBridge Pipes using CDK. And in another blog post, he also walks through a pattern of SNS → SQS → EventBridge Pipes with CDK.

With AppSync supporting JS resolvers, Benoît Bouré explains how we could write reusable code for AppSync JavaScript resolvers with the prerequisites and how the JS resolvers could be tested with AWS CLI.

With AWS Application Composer going GA, Athavan Theivendram sets the context needed for developers which is a pre-requisite to building applications from Application Composer.

For anyone worried about the myths and concerns of Serverless, Hendrik Nehnes’ in defense of Serverless talks about the past when he had to manage/maintain servers during different seasons, and now with Serverless and its capabilities which have made today’s infra maintenance and management seamless.

Folks blame Serverless for introducing latency well, the reality is that you have your resources in a far-off geographical location, learn about it from Allen Helton’s experiment - Location is everything. Allen also shares a tip for Amplify users in his tweet.

Marcin Sodkiewicz shares about the need for SQS partial failures when to use them, and also how one implements and uses them in their architectures with examples and also some key factors to keep in mind.

Have you always thought “How do I test my Serverless app?“ Ran Isenberg has you covered with a Serverless testing blog series where he gives you insights about the guide to testing Serverless and Lambda with best practices and considering the testing pyramid.

Andreas Wittig’s podcast Cloudnaut with Vilius Kukanauskas is about Serverless and DevOps a match made in heaven! With Serverless, the concept of IaC, Pipelines, and Security is all part of the Serverless developer’s plate.

AWS SAM trick. Store your account id in SSM. Use {{resolve:ssm}} dynamically in a Mapping block. CloudFormation doesn’t allow parameters, pseudo or otherwise. Mappings: Environments: Dev: MySFN: arn:aws:states:us-east-2:{{resolve:ssm:account_id}}:stateMachine:MySFN

⚒️ What's happening with AWS Serverless tools

Bref 2.0 is released, bref is AWS Lambda with PHP runtimes!

GraphBolt is now available in beta. This has revolutionized the way you develop, test and manage your AppSync APIs.

Introducing Mountpoint for Amazon S3, a high performance open source file client.

Sync in real-time between Step Functions Workflow studio and your local machine sfn-workflow-studio-sync has an update with YAML and JSON toggles.

📢New feature in evb-cli that you never knew you needed! `evb find-usages` lets you search all rules on a bus for property usages in their event patterns. Helps you to better understand your #eventdriven applications and speeds up troubleshooting. #aws #serverless

👨‍💻 Word from the author

Congratulations to the new AWS Heroes - Aidan Steele (AWS Serverless Hero), Ananda Dwi Rahmawati (AWS Containers Hero) and Wendy Wong (AWS Data Hero).

Happy Birthday to Amazon S3. It’s 17 years old now and has evolved a lot making it the most used service across all our architectures.

Thanks for the great response to my previous newsletter issues and also blog posts. I’m open to feedback, so feel free to DM me on Twitter or LinkedIn.

Until next time, happy building on Serverless!
