Overview of this book

Event-driven architecture in Golang is an approach used to develop applications that shares state changes asynchronously, internally, and externally using messages. EDA applications are better suited at handling situations that need to scale up quickly and the chances of individual component failures are less likely to bring your system crashing down. This is why EDA is a great thing to learn and this book is designed to get you started with the help of step-by-step explanations of essential concepts, practical examples, and more. You’ll begin building event-driven microservices, including patterns to handle data consistency and resiliency. Not only will you learn the patterns behind event-driven microservices but also how to communicate using asynchronous messaging with event streams. You’ll then build an application made of several microservices that communicates using both choreographed and orchestrated messaging. By the end of this book, you’ll be able to build and deploy your own event-driven microservices using asynchronous communication.

Domain-driven design

Domain-driven design (DDD) is a very large and complex topic, with entire books devoted to the use and implementation of the many patterns and methodologies that are brought together. I won’t try to fit all of it into this chapter, much less this section, so we’ll be taking a high-level look at the key strategic patterns that are useful to us as we design and develop event-driven applications. As for the tactical patterns, we’ll be seeing examples of their use throughout the rest of the book.

Going deeper into DDD

For an in-depth look at DDD, I can recommend both Domain-Driven Design: Tackling Complexity in the Heart of Software by Eric Evans, as an original introduction to the topic, and Implementing Domain-Driven Design by Vaughn Vernon, for the expansion of the topic and a deeper dive into the strategic patterns of DDD. Finally, Patterns, Principles, and Practices of Domain-Driven Design by Scott Millett with Nick Tune rounds out the...
