Learning Domain-Driven Design

The hardest problems in software design are rarely technical. They begin when design drifts away from the business it serves: brittle services, tangled dependencies, systems that resist change as the business evolves. Learning Domain-Driven Design, second edition, gives software architects and engineers a practical framework for aligning software design with business strategy, from high-level architecture down to modeling business processes and rules. In this new edition of his best-selling guide, Vlad Khononov explains DDD through patterns, collaborative modeling techniques, and a running real-world example. You'll explore bounded contexts, aggregates, domain events, EventStorming, microservices, and event-driven architecture, with every concept in service of a design decision. New material on domain analysis, balanced coupling, and AI-assisted software engineering updates DDD for the way software is built today. The result is a reference you'll return to as systems, teams, and priorities change. - Analyze business strategy and its impact on software design decisions - Design system and team boundaries for autonomy and modularity - Tackle complex business logic with advanced tactical patterns - See how DDD supports the fundamental principles of modular design - Introduce DDD gradually and pragmatically, even in legacy systems
