Microservices with Go

By: Alexander Shuiskov

Overview of this book

This book covers the key benefits and common issues of microservices, helping you understand the problems microservice architecture helps to solve, the issues it usually introduces, and the ways to tackle them. You’ll start by learning about the importance of using the right principles and standards in order to achieve the key benefits of microservice architecture. The following chapters will explain why the Go programming language is one of the most popular languages for microservice development and lay down the foundations for the next chapters of the book. You’ll explore the foundational aspects of Go microservice development including service scaffolding, service discovery, data serialization, synchronous and asynchronous communication, deployment, and testing. After covering the development aspects, you’ll progress to maintenance and reliability topics. The last part focuses on more advanced topics of Go microservice development including system reliability, observability, maintainability, and scalability. In this part, you’ll dive into the best practices and examples which illustrate how to apply the key ideas to existing applications, using the services scaffolded in the previous part as examples. By the end of this book, you’ll have gained hands-on experience with everything you need to develop scalable, reliable and performant microservices using Go.

Asynchronous Communication

In the previous chapter, we illustrated how services can communicate with each other using a synchronous request-response model. There are other communication models that provide various benefits to the application developer, such as asynchronous communication, which we are going to cover in this chapter.

In this chapter, you are going to learn the basics of asynchronous communication and some common techniques for using it, as well as some benefits and challenges it brings to microservice developers. We will cover a popular piece of asynchronous communication software, Apache Kafka, and illustrate how to use it for establishing communication between our microservices.

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

  • Asynchronous communication basics
  • Using Apache Kafka for messaging
  • Asynchronous communication best practices

Let’s proceed to the basics of asynchronous communication.
