Become the developer your team turns to when AWS breaks.

Why does S3 go public without warning?
Why does "Access Denied" appear when the IAM policy looks perfect?
Why do EC2 bills spike even when everything is “off”?

This book is not another theory-filled AWS manual.

It’s a survival guide for real-world developers, DevOps engineers, and cloud architects who battle vague errors, production outages, and budget nightmares.

Inside, you’ll find 60+ high-impact, field-tested chapters covering:

• Unexplained Lambda timeouts and cold start pain
• S3 lifecycle rules that silently fail
• IAM permission traps and wildcards that backfire
• EC2 money leaks, EBS bloat, and scaling chaos
• Cognito token expiration, MFA issues, and hosted UI bugs

Every chapter includes:

• CLI commands that fix real problems
• Misconfiguration checklists
• Root cause breakdowns
• Tips from developers who've been burned
