AWS SAM (Serverless Application Model)

AWS SAM is an IaC framework for building serverless applications.

Core Principles

1. Infrastructure as Code (IaC) - Manage all resources in template.yaml
2. Single Responsibility Function Design - Each Lambda focuses on one function
3. Principle of Least Privilege - IAM policies should be minimal
4. Local-First Development - Test with sam local before deploying
