In this excerpt from "Build a Serverless Application with AWS Lambda - Hands On!," we'll illustrate how versioning in AWS Lambda can help you maintain separate environments for development, testing, and production - and allow you to quickly roll back changes in the event of trouble on your live Lambda-based web app. We'll also use Canary to automatically divide traffic between different deployments, create and use a test stage and promote it to production, and use version aliases to simplify the configuration of Lambda.
