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.

Event Foundations

In the first part of this book, we discussed what event-driven architectures are and the other patterns we might use when developing them. We then dove into the design and planning of an application, and we’ll be implementing event-based approaches to the existing synchronous methods it uses now. This next part will introduce you to event usage, tracking, and forms of communication, and will also refactor the MallBots application into a fully event-driven application. Each chapter will cover a different pattern and accompanying implementation, which will build on what was learned in the previous chapters.

In this chapter, we will take a look at how the application is being built and how the modules of the application communicate. After a tour of the application, we will refactor portions of the application to use domain events, a domain-driven design pattern, to set the stage for our future refactoring efforts.

We will work with the following main topics...
