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.

What makes a good microservice framework?


What makes a microservice framework is an incredibly good question and one that is open to a multitude of opinions. In an attempt to remove the subjectivity, we will break down the features of a good framework and try to allocate a score for each of these functions in a consistent way. The following diagram is a hierarchical mind map of the features that I deem necessary. When you are assessing the framework that is the best for you and your project, you can use this framework, adding or removing any of the attributes that may be relevant:

Here are some of the features you need to keep in mind while choosing a good framework:

  • Ability to interface with other frameworks: It must be possible to interact with any service built with the framework by clients who are not built using the same framework:
    • Implement standards: A standard message protocol should be used to maximize interaction, for example:
      • JSON-RPC
      • Thrift
      • Protocol Buffers
      • JSON
    • Open: The framework...
