Serverless Framework Intro
The document discusses the Serverless Framework, which is a build tool that makes it easy to setup and invoke Lambda functions on AWS. It allows developers to manage multiple Lambda functions across different regions and stages, and share code between functions. The Serverless Framework supports Node.js, Python, Java/Scala and other runtimes. Functions are defined in a serverless.yml file along with triggers like HTTP events, S3 uploads, schedules and more. The framework handles deployments to AWS and other cloud providers.
