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.

Introduction to AWX

AWX sets out to solve the problems associated with Ansible automation in an enterprise environment. To maintain our hands-on focus, let's consider the organic growth scenario we discussed in Chapter 1, Building a Standard Operating Environment on Linux. In a small environment where Ansible has been implemented, you might have just one or two key people responsible for writing and running playbooks against the environment. In this small scenario, it is reasonably easy to know who has run which playbooks and what the latest versions are, and the training requirements for Ansible are low as only a small number of key people are responsible for its use.

As the environment scales to enterprise sizing, so do the number of Ansible operators. If all of those responsible for running Ansible have it installed on their own machines, and all have local copies of the...
