About this book

Linux plays a significant role in modern data centers and offers many different ways to deploy and manage a Linux environment within your own data center or in the private/public cloud. This book covers everything you need to know about using the Linux operating system in your data center or the cloud.

This Linux book starts by helping you understand the command line and how to work with files, packages, and filesystems. You'll then begin administering network services, hardening security, and learn about cloud computing, containers, and orchestration. Once you've learned how to work with the command line, you'll explore the most important Linux commands and master users, processes, and services administration. You'll also discover how to harden Linux security using iptables. As you advance, you'll be able to leverage containers, hypervisors, virtual machines, Ansible, and Kubernetes, and learn how to deploy Linux on AWS, Azure, and OpenStack.

By the end of this book, you'll be well-versed with Linux and have the confidence to work with Linux from bare metal to the cloud in a pure DevOps way.
