This book is a practical guide to scaling web applications from a few users to millions. Ejsmont covers the full stack: frontend optimization, web servers, caching layers, asynchronous processing, databases, search engines, and infrastructure.
Unlike academic distributed systems books, this one focuses on the decisions startups actually face: when to add a cache layer, how to shard your database, when to move from a monolith to services, and how to handle eventual consistency in practice.
Each chapter includes architecture diagrams, decision frameworks, and real-world tradeoffs. The message queue chapter is particularly practical — it covers when to use queues, which patterns work, and common pitfalls.
My Review
The most practical scaling book for web developers. DDIA is deeper on theory; this book is better on "what do I actually do on Monday morning."
The progression mirrors how startups actually grow: single server → separate database → add caching → add queues → shard → microservices. Each step is motivated by a real scaling pain point.
Who should read it: Backend developers at startups or growing companies. Also great interview prep for system design questions with a more practical bent.
Skip if: You're at a company where infrastructure is handled by a dedicated platform team and you won't make these decisions yourself.
