Description

The AWS Serverless Application Model (SAM) supplies built-in best practices for deploying your serverless applications. A REST API built with AWS SAM can be configured using shorthand syntax to express event source mappings, database relationships, and function declarations.

In this lab, you will use the AWS SAM CLI to develop a simple REST API backed by a Lambda function and a DynamoDB table. The lab will cover the built-in conventions and default values that are present in a simple SAM application.

  • Use the AWS SAM CLI to define the Serverless API, function, and table resources
