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.

There is nothing wrong with the lineinfile approach we discussed previously when it comes to making small numbers of changes in a well-controlled environment, yet let us consider a more robust approach to configuration management, better suited to a large organization.

We will start by considering scalable methods for simple static configuration changes (that is, those that are the same across all servers) in the next section.

Making scalable static configuration changes

It is vital that the configuration changes that we make are version controlled, repeatable...
