The Complete AWS Interview Playbook

Most AWS interview guides hand you flashcards. This one helps you understand the material the way someone who's actually run it in production does.If you've ever memorized a definition, repeated it in an interview, and then frozen the moment someone asked "...but why would you use that?" - this book is built for exactly that gap. Every question is answered the way an experienced engineer would explain it out loud across the table: the plain-English version first, then when you'd actually reach for it in the real world, then the gotcha the interviewer is really probing for. No padded three-tier answers designed to inflate a page count. One clear, honest answer per question.Written by a full-stack developer and AI engineer with 20+ years building enterprise systems across the US and Canada, this covers the AWS that candidates face today - not the EC2-and-S3 world older guides still assume.What's inside - 23 chapters, 140+ questions and answers: - Core compute: EC2, ECS, Fargate, and Lambda - and when to choose each- Containers and Kubernetes: Docker, ECS vs. EKS, and scaling containers safely- Networking, API Gateway, CloudFront, and Route 53 traffic management- Databases: RDS, Aurora, and DynamoDB (including single-table design)- Storage, messaging (SQS, SNS, EventBridge, Step Functions), and caching- Auto Scaling, self-healing, and high-availability patterns- Security and IAM, infrastructure as code (CloudFormation, CDK, Terraform), and CI/CD- Cost optimization and FinOps - where the money actually leaks- Data and analytics (Glue, Athena, Redshift, Kinesis) and the AI/ML stack (SageMaker, Bedrock)- A full scenario and system-design round, plus a rapid-fire screening drillWhere the syntax genuinely teaches something - an IAM policy, a DynamoDB key layout, a CDK construct - you'll find a short, real code example. Everywhere else, it's plain, honest explanation.This book is for you if you're: - Preparing for an AWS developer, cloud engineer, DevOps, or solutions architect interview- Tired of guides that list facts but never explain the reasoning- Aiming to understand AWS deeply enough to speak to it with real confidenceWherever there's a trade-off - Fargate vs. EC2, Aurora vs. DynamoDB, CloudFormation vs. Terraform - this book takes a side, tells you why, and tells you when the other side wins. Because "it depends" is the truth in cloud architecture, but it's a weak interview answer on its own.
