Led by two enterprise programming experts, readers will learn how to apply the patterns and techniques that help control project complexity - and make systems easier to build, support, and upgrade - right from the start. This Second Edition features new deep dives on domain modeling, Command Query Responsibility Segregation (CQRS), and event sourcing models.

A software architect’s digest of core practices, pragmatically applied

Designing effective architecture is your best strategy for managing project complexity–and improving your results. But the principles and practices of software architecting–what the authors call the “science of hard decisions”–have been evolving for cloud, mobile, and other shifts. Now fully revised and updated, this book shares the knowledge and real-world perspectives that enable you to design for success–and deliver more successful solutions.

In this fully updated Second Edition, you will:

• Learn how only a deep understanding of domain can lead to appropriate architecture
• Examine domain-driven design in both theory and implementation
• Shift your approach to code first, model later–including multilayer architecture
• Capture the benefits of prioritizing software maintainability
• See how readability, testability, and extensibility lead to code quality
• Take a user experience (UX) first approach, rather than designing for data
• Review patterns for organizing business logic
• Use event sourcing and CQRS together to model complex business domains more effectively

• Delve inside the persistence layer, including patterns and implementation.
