A “software architecture” defines the fundamental, high-level structure of a software system, acting as a blueprint for its components, their relationships, and how they interact. As a developer, having a command of the principles, patterns, and vocabulary of software architecture empowers you to contribute meaningfully throughout an application’s lifecycle—from its initial design to its deployment in production.

This book is a fast-paced introduction to the foundational ideas of software architecture, written for developers and aspiring architects. Creative illustrations and diagrams, hilarious disaster stories, “in action” missions, and a full repository of example code teach you how to spot design mistakes and understand architectural tradeoff decisions. Along the way, you’ll also explore author Matt Erman’s 5-step Architectural Thinking Process for reliably turning vague business requests into clear, defensible technical decisions.
