Overview of this book

Go is the go-to language for DevOps libraries and services, and without it, achieving fast and safe automation is a challenge. With the help of Go for DevOps, you'll learn how to deliver services with ease and safety, becoming a better DevOps engineer in the process. Some of the key things this book will teach you are how to write Go software to automate configuration management, update remote machines, author custom automation in GitHub Actions, and interact with Kubernetes. As you advance through the chapters, you'll explore how to automate the cloud using software development kits (SDKs), extend HashiCorp's Terraform and Packer using Go, develop your own DevOps services with gRPC and REST, design system agents, and build robust workflow systems. By the end of this Go for DevOps book, you'll understand how to apply development principles to automate operations and provide operational insights using Go, which will allow you to react quickly to resolve system failures before your customers realize something has gone wrong.

However, it misses the bigger picture of what a cloud service provider is. A cloud service provider is a collection of hundreds of application-hosting, data, compliance, and computing infrastructure services that run in hundreds of data centers across the globe and are exposed through a fully programmable API.

In this chapter, we will learn how to interact with a cloud API using Microsoft Azure. We'll start by learning a bit about the nature of the APIs, including how they are described and where to find additional documentation about them. We'll learn the fundamentals of identity, authentication, and authorization. We&apos...
