AWS Lambda Automated Deployment

Objective

This blog details the steps to build, deploy and maintain different versions of Lambda functions across various product stages such as development, testing, staging and production on multiple AWS accounts.

AWS Lambda Versions and Aliases

AWS Lambda lets you run code without provisioning or managing servers. You are charged based on the time and resources consumed by your code when it runs – there is no charge when your code is not running. All of this makes AWS Lambda very easy to jump straight into your business logic and not worry about the infrastructure setup.
