AWS Lambda Powertools is a developer toolkit to implement Serverless best practices and increase developer velocity. It started as an open-source project in 2020 focused in making Tracing, Logging, and Metrics easier. Fast-forward, Powertools added 13 more features, grew a vibrant community who regularly contributes up to 60% of our releases, now covering a plethora of use cases: REST and GraphQL APIs, Batch processing, Idempotency, Feature Flags, Data Validation, and more. You’ll learn why this developer toolkit was created, key use cases, and find out how you can adopt common industry and AWS best practices in seconds. We’ll also cover two of the most anticipated new features coming in 2023, and live demo(s).
