Testing and Deployment Best Practices for AWS Lambda-Based Applications

Level: 200

AWS Lambda has changed the way developers think about building applications. From the granularity of the function-as-a-service model to the event-driven paradigm, Lambda-based applications require some different practices for testing and deployment vs. traditional software development. In this tech talk, we’ll discuss various capabilities of AWS Lambda that you can use to your benefit when it comes to testing and deploying your applications; aliases, versioning, and safe deployments with rollbacks. We’ll cover how to think about environmental stages and code promotion so you can safely deploy and test your applications without impacting customers or service-level availability. We’ll also explore what is possible today for both local and AWS cloud-based testing of your Lambda-based applications.
