Hands-On Enterprise Automation on Linux

By: James Freeman

Overview of this book

Automation is paramount if you want to run Linux in your enterprise effectively. It helps you minimize costs by reducing manual operations, ensuring compliance across data centers, and accelerating deployments for your cloud infrastructures. Complete with detailed explanations, practical examples, and self-assessment questions, this book will teach you how to manage your Linux estate and leverage Ansible to achieve effective levels of automation. You'll learn important concepts on standard operating environments that lend themselves to automation, and then build on this knowledge by applying Ansible to achieve standardization throughout your Linux environments. By the end of this Linux automation book, you'll be able to build, deploy, and manage an entire estate of Linux servers with higher reliability and lower overheads than ever before.

Building a Standard Operating Environment on Linux

This chapter provides a detailed exploration of the Standard Operating Environment (henceforth, SOE for short) concept in Linux. Although we will go into much greater detail later, in short, an SOE is an environment where everything is created and modified in a standard way. For example, this would mean that all Linux servers are built in the same way, using the same software versions. This is an important concept because it makes managing the environment much easier and reduces the workload for those looking after it. Although this chapter is quite theoretical in nature, it sets the groundwork for the rest of this book.

We will start by looking at the fundamental definition of such an environment, and then proceed to explore why it is desirable to want to create one. From there, we will look at some of the pitfalls of an SOE...
