How to prepare (10 weeks, part time)
- Weeks 1–3: IAM, VPC and EC2 in a real account. Build a VPC with public and private subnets by hand.
- Weeks 4–6: storage and databases. Practice choosing the right one for a scenario.
- Weeks 7–8: serverless and decoupling (Lambda, SQS, SNS) and high availability patterns.
- Weeks 9–10: mock exams. For every wrong answer, write down why the right answer is right.
Set a billing alarm on day one, and delete resources after each lab.
