Building Microservices with Go

By: Nic Jackson

Overview of this book

Microservice architecture is sweeping the world as the de facto pattern to build web-based applications. Golang is a language particularly well suited to building them. Its strong community, encouragement of idiomatic style, and statically-linked binary artifacts make integrating it with other technologies and managing microservices at scale consistent and intuitive. This book will teach you the common patterns and practices, showing you how to apply these using the Go programming language. It will teach you the fundamental concepts of architectural design and RESTful communication, and show you patterns that provide manageable code that is supportable in development and at scale in production. We will provide you with examples on how to put these concepts and patterns into practice with Go. Whether you are planning a new application or working in an existing monolith, this book will explain and illustrate with practical examples how teams of all sizes can start solving problems with microservices. It will help you understand Docker and Docker-Compose and how it can be used to isolate microservice dependencies and build environments. We finish off by showing you various techniques to monitor, test, and secure your microservices. By the end, you will know the benefits of system resilience of a microservice and the advantages of Go stack.

Chapter 5. Common Patterns

Before we take a look at some frameworks which can help you build microservices in Go, we should first look at some of the design patterns that will help you avoid failure.

I am not talking about software design patterns like factories or facades, but architectural designs like load balancing and service discovery. If you have never worked with microservice architecture before, then you may not understand why these are needed, but I hope that by the end of the chapter you will have a solid understanding why these patterns are important and how you can apply them correctly. If you have already successfully deployed a microservice architecture, then this chapter will give you greater knowledge of the underlying patterns which make your system function. If you have not had much success with microservices, then possibly you did not understand that you need the patterns I am going to describe.

In general, there is something for everyone, and we are going to look at not...
