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
