Preface

Since its first release, the Go programming language has gained popularity among all types of software developers. Simple language syntax, ease of use, and a rich set of libraries made Go one of the primary languages for writing different kinds of software, from small tools to large-scale systems consisting of hundreds of components.

Among the primary Go use cases is microservice development – the development of individual applications, called microservices, that can play various roles, from processing payments to storing user data. Organizing a large system as a set of microservices often brings multiple advantages, such as increasing the development and deployment speed, but also brings multiple types of challenges. Among such challenges are service discovery and communication, integration testing, and service monitoring.

In this book, we will illustrate how to implement Go microservices and establish communication between them, how to enable the deployment of individual microservices and secure their interactions, and how to store and retrieve service data and provide service APIs, enabling other applications to use our microservices. You will learn about some of the industry’s best practices related to all of these topics and get a detailed overview of the possible challenges along the way, as well as the possible benefits. The knowledge that you will gain by reading this book will help you to both create new microservices and efficiently maintain the existing ones. I hope this journey will be exciting for you!
