Overview of this book

Linux plays a significant role in modern data center management and provides great versatility in deploying and managing your workloads on-premises and in the cloud. This book covers the important topics you need to know about for your everyday Linux administration tasks. The book starts by helping you understand the Linux command line and how to work with files, packages, and filesystems. You'll then begin administering network services and 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 essential Linux commands for managing users, processes, and daemons and discover how to secure your Linux environment using application security frameworks and firewall managers. As you advance through the chapters, you'll work with containers, hypervisors, virtual machines, Ansible, and Kubernetes. You'll also learn how to deploy Linux to the cloud using AWS and Azure. By the end of this Linux book, you'll be well-versed with Linux and have mastered everyday administrative tasks using workflows spanning from on-premises to the cloud. If you also find yourself adopting DevOps practices in the process, we'll consider our mission accomplished.

Technical requirements

First, you should be familiar with the Linux command-line Terminal in general. Intermediate knowledge of Linux will help you understand some of the intricacies of the practical illustrations used throughout this chapter. You should also be proficient in using a Linux-based text editor. For the hands-on examples, we recommend setting up a lab environment similar to the one we're using. You'll find the related instructions in the README file included with the complementary resources in this book's GitHub repository for this chapter.

If you don't configure a lab environment, you will still benefit from the detailed explanations associated with the practical examples in this chapter.

Now, let's start our journey by covering the introductory concepts surrounding Ansible.
