Mastering Linux Administration

By: Alexandru Calcatinge, Julian Balog

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.

In this chapter, we emphasized the importance of virtualization and containerization.

We showed you the difference between VMs and containers. You learned how to deploy a VM using KVM. We also showed you how to quickly create a VM inside GNOME using Boxes. With those two assets, you are prepared to start your path into virtualization with no fears. We also showed you what containers are, how they work, and why they are so important. Containers are the foundation of the modern DevOps revolution and you are now ready to use them. We also taught you about Docker, the basic commands for a sleek use. You are now ready to start the cloud journey, as this will be the final part of this book.

Virtualization and container technologies are at the heart of cloud technologies. This is why, in the next chapter, we will introduce you to the basics of cloud technologies, OpenStack, AWS, Azure, Ansible, and Kubernetes.
