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.

What is a message bus?

The term message bus originates from enterprise architecture patterns. The pattern aims to:

  • Create a common data model and command set shared through a set of shared interfaces
  • Allow decoupling of applications so that old ones could be taken away and new ones added with minimal disruption

A shared file could technically satisfy the definition of a message bus (and that is kind of what Kafka is).

In modern software development, we have many different flavors of message buses at our disposal. Purists may argue that some of the tools suggested here aren’t technically message buses—they are message queues. The distinction is that the definition of message bus does not say anything about guaranteed ordering or other queue-like semantics. Truthfully, I think it’s unimportant, and it’s more important to ensure you pick the correct tool for what you are trying to achieve. Next, I have included a few popular message bus...
