Domain-Driven Design with Golang

Overview of this book

Domain-driven design (DDD) is one of the most sought-after skills in the industry. This book provides you with step-by-step explanations of essential concepts and practical examples that will see you introducing DDD in your Go projects in no time. Domain-Driven Design with Golang starts by helping you gain a basic understanding of DDD, and then covers all the important patterns, such as bounded context, ubiquitous language, and aggregates. The latter half of the book deals with the real-world implementation of DDD patterns and teaches you how to build two systems while applying DDD principles, which will be a valuable addition to your portfolio. Finally, you’ll find out how to build a microservice, along with learning how DDD-based microservices can be part of a greater distributed system. Although the focus of this book is Golang, by the end of this book you’ll be able to confidently use DDD patterns outside of Go and apply them to other languages and even distributed systems.

DDD for Distributed Systems

In the previous chapter, we built a microservice from scratch. The microservice we built communicated with another microservice in a synchronous fashion to attain some data to allow it to fulfill a business requirement. In this chapter, we are going to explore some other patterns for how microservices might communicate and share data as part of a larger distributed system. We will cover some patterns that have become synonymous with domain-driven design (DDD), such as Command and Query Responsibility Segregation (CQRS) and event-driven architecture (EDA). However, we will also cover some general distributed system concepts such as message buses and resilient patterns. These are not strictly domain-driven concepts but are complementary nonetheless and are certainly useful.

By the end of this chapter, you will be able to answer the following questions:

  • What do we mean by a distributed system?
  • What are CQRS and EDA?
  • What is event sourcing...
