Module Overview

In this module, we practice the critical skill of choosing the right AWS service for a given scenario, a skill tested heavily in certifications and applied daily in real cloud work.

  1. Service Comparison Drills: EC2 vs Lambda, S3 vs EBS vs EFS, RDS vs DynamoDB.
  2. Architecture Reasoning: How to evaluate tradeoffs between services.
  3. Scenario Practice: Real-world "which service should I use?" exercises.

By the end of this module, you'll be able to confidently justify service selections across compute, storage, and database domains.
