Why this guide
- Built around the 4 weighted SAA-C03 domains — Secure (30%) and Resilient (26%) get the most focus
- Service comparison tables — RDS vs DynamoDB, S3 storage classes, ALB vs NLB, EC2 purchasing options
- 60 most-tested services — what shows up in scenarios and what you can safely deprioritize
- Designed for printing — full guide, two 1-page cheat sheets, and a 1-page pocket card
Who this is for
- Cloud engineers and solutions architects preparing for the SAA-C03
- Systems administrators transitioning from on-prem infrastructure to AWS
- Developers who design and deploy production workloads on AWS
- Consultants and pre-sales engineers who need AWS-validated architecture vocabulary
- Anyone with hands-on AWS experience who wants a structured, weighted exam review
