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.

Employees come and go, meaning access details must be updated accordingly. Indeed, access management can, in a busy organization, be a full-time job in itself!

In this chapter, we will explore, through hands-on examples, how to automate your user and access management through Ansible, in a way that is consistent with our Standard Operating Environment (SOE) model.

The following topics will be covered in this chapter:
