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.

Popular serialization formats

There are many popular serialization formats and protocols used in the industry. Let’s cover some of the most popular formats:

  • XML
  • YAML
  • Apache Thrift
  • Apache Avro
  • Protocol Buffers

This section will provide a high-level overview of each one, as well as some key differences between these protocols.

XML

XML is one of the earliest serialization formats for web service development. It was created in 1998 and is still widely used in the industry, especially in enterprise applications.

XML represents data as a tree of nodes called elements. An element example would be <example>Some value</example>. If we serialized our metadata structure mentioned above, the result would be the following:

<Metadata><ID>123</ID><Title>The Movie 2</Title><Description>Sequel of the legendary The Movie</Description><Director>Foo Bars</Director></Metadata>
