Cloud for interviews — you’ve built on Lambda, so this is about being able to articulate it, not learn it. Guided order first, full note grid below.
Learn in this order
- Lambda — cold starts, triggers, Lambda + Spring Boot (your real experience — practice saying it out loud)
- Core Services — S3, EC2, RDS, SQS: what each is for in one line
- IAM — roles vs. policies, least privilege
- Architecture Patterns — when serverless vs. containers vs. EC2
Your edge
You have 7 years of hands-on AWS. The gap isn’t knowledge, it’s framing. For
each note, write the “at my last job I used this to…” sentence — that’s what
interviewers actually score.
