Overview of this book

Domain-Driven Design (DDD) makes available a set of techniques and patterns that enable domain experts, architects, and developers to work together to decompose complex business problems into a set of well-factored, collaborating, and loosely coupled subsystems. This practical guide will help you as a developer and architect to put your knowledge to work in order to create elegant software designs that are enjoyable to work with and easy to reason about. You'll begin with an introduction to the concepts of domain-driven design and discover various ways to apply them in real-world scenarios. You'll also appreciate how DDD is extremely relevant when creating cloud native solutions that employ modern techniques such as event-driven microservices and fine-grained architectures. As you advance through the chapters, you'll get acquainted with core DDD’s strategic design concepts such as the ubiquitous language, context maps, bounded contexts, and tactical design elements like aggregates and domain models and events. You'll understand how to apply modern, lightweight modeling techniques such as business value canvas, Wardley mapping, domain storytelling, and event storming, while also learning how to test-drive the system to create solutions that exhibit high degrees of internal quality. By the end of this software design book, you'll be able to architect, design, and implement robust, resilient, and performant distributed software solutions.

Part 1: Foundations

While the IT industry prides itself on being at the very bleeding edge of technology, it also oversees a relatively high proportion of projects that fail outright or do not meet their originally intended goals for one reason or another. In Part 1, we will look at the reasons for software projects not achieving their intended objectives and how practicing Domain-Driven Design (DDD) can significantly help improve the odds of achieving success. We will do a quick tour of the main concepts that Eric Evans elaborated on in his seminal book of the same name and examine why/how it is extremely relevant in the age of distributed systems. We will also look at several popular architecture styles and programming paradigms and explore how DDD fits in the scheme of things.

This part contains the following chapters:

  • Chapter 1, The Rationale for Domain-Driven Design
  • Chapter 2, Where and How Does DDD Fit?
