Introduction to AWS SAM

Hello! Today we'll explore AWS SAM, the Serverless Application Model. It's an open-source framework designed to help you build serverless applications on AWS more efficiently.

Think of SAM as a powerful extension to AWS CloudFormation, specifically tailored for serverless resources.

AWS CloudFormation is a robust service for defining infrastructure as code. However, building serverless applications directly with CloudFormation can be quite verbose.

• A simple AWS Lambda function often requires defining the Lambda resource itself, an IAM role with permissions, and possibly an API Gateway endpoint.
• This can lead to many lines of configuration for even basic setups.
