Event-Driven Architecture in Golang

By: Michael Stack

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.

Transactional Messaging

In this book, we have transformed an application into an asynchronous one, which removes a lot of issues that arose from the tightly coupled and temporally bound nature of synchronous communication. Nearly all communication in the application is now made with a message brokered through NATS JetStream, providing loose coupling for the application components. However, despite all the advances we have made, we still face issues that all distributed systems suffer from.

In this chapter, we are going to discuss the following main topics:

  • Identifying problems faced by distributed applications
  • Exploring transactional boundaries
  • Using an Inbox and Outbox for messages
