Overview of this book

Ubuntu is a Debian-based Linux operating system built on top of the Debian architecture. It is used to make operating systems for multiple platforms, including phones, desktops, TVs and mobiles. It has made some serious progress in the realms of efficiency and user friendliness. With evolving technology trends, demands on software have changed, with more and more skilled users. Over the past few years, services such as Facebook, Twitter, and push notifications on smartphones mean that users are used to being up to date with everything that happens all the time. With SignalR, the applications stay connected and will generate notifications when something happens either from the system or by other users. This provides new opportunities for the system administrators, to enter this new and exciting world of real-time application development. This is a concise and a cost-friendly guide, packed with up-to-date essentials on Ubuntu Server fundamentals. It will guide you through deploying and configuring Ubuntu servers in your office environments. You’ll start by installing Ubuntu Server, then move to the most useful aspect —the command-line interface inside it. You’ll extend your knowledge by learning how to administrate and configure Ubuntu Server. You will also see how to deploy services on Ubuntu Server and find out how to secure it. You’ll get to grips with the virtualization and cloud computing facilities provided by Ubuntu, and finally, you’ll gain some very useful tips.

Chapter 5. Virtualization and Cloud Computing inside the Ubuntu Server

Virtualization and Cloud computing are some of the hottest topics in system administration communities nowadays. They give system administrators the possibility to run more servers on the same hardware and use resources in a reliable manner. The Cloud concept, which is already based on virtualization, provides much more benefits, especially via security and new business models such as SaaS, PaaS, and IaaS.

Ubuntu provides a good set of virtualization and Cloud computing platforms. In this chapter, we will have a look at how the Ubuntu Server handles the most well known platforms:

  • In the first section, we will focus on virtualization. We will discover how to manage three big virtualization programs, namely KVM, XenServer, and Docker.

  • In the second section, we will take a look at the Cloud capabilities provided by the Ubuntu Server.
