Mastering AWS SAM: The AWS Serverless Application Model

SAM stands for Serverless Application Model.

The AWS Serverless Application Model (SAM) is an open-source framework for building serverless applications. It provides shorthand syntax to express functions, APIs, databases, and event source mappings.

AWS SAM Overview

AWS SAM comes in two parts

• SAM Templates: Using shorthand syntax to express resources and event source mappings, it provides infrastructure as code (IaC) for serverless application.
• SAM CLI: Provides tooling for local development, debugging, build, packaging, and deployment for serverless applications.

Sam Serverless Resources

• AWS:Serverless::Function
• AWS:Serverless::Api
• AWS:Serverless::HttpApi
• AWS:Serverless::SimpleTable
• AWS:Serverless::LayerVersion

AWS SAM Globals

Globals help you make your SAM templates even smaller by enabling you to re-use attributes throughout. Also, using the same template to build the same infrastructure ensures consistency across multiple environments.
