Infrastructure as Code: Comparing SAM, CDK, and CloudFormation

Описание: Are you preparing for the AWS Certified Developer – Associate exam? Infrastructure as Code (IaC) is a massive topic on the test, and in this video, we break down the three most essential AWS tools you need to know: CloudFormation, SAM, and the CDK.

We’ll explore why IaC is a game-changer for cloud development—moving away from "ClickOps" toward automated, repeatable, and version-controlled infrastructure.

In this video, we cover:

Declarative vs. Imperative Approaches: The differences between writing templates in YAML (CloudFormation/SAM) and using general-purpose programming languages like Python or TypeScript (CDK).

AWS SAM (Serverless Application Model): How SAM acts as a specialized toolkit to simplify serverless deployments and IAM roles.

The Deployment Lifecycle: Understanding the cdk synth command and how the CDK generates CloudFormation templates.

Essential Exam Safety Features: Learn about Change Sets, Rollbacks, and the Deletion Policy attribute to protect your production data.

Managing Complex Stacks: How to share resources between stacks using Export/Import Value and how to avoid the "Deletion Trap."

Whether you’re choosing the right tool for your next project or looking to ace your AWS certification, this guide provides the clarity you need to succeed.
