The applications for virtualization technology in modern IT are endless, and you will find them everywhere. The limits are only defined by your own computer hardware. Modern virtualization software does not even limit you to run only one parallel OS, but you can run multiple systems in parallel. For example, if you are currently working on a Windows computer, you can run another operating system such as Linux or macOS in parallel to a simple Windows application on your desktop. Simply put, it is a technology to run separate operating systems parallel to your main operating system on the same computer. It is a very hot topic and the core IT skill at the moment is virtualization. We will also show you how to work with VirtualBox, and afterward show you how you can install your first CentOS 7 virtual machine in VirtualBox. In this section, we will give you an overview of the concepts of virtualization. Then, we will create a new CentOS 7 virtual machine ( VM) using a free virtualization software called VirtualBox. The first chapter of this book is about installing Linux here we will be starting easy by introducing you to the concepts of virtualization. Also, it's good to know that the development of this OS is very strong and updates are well selected and suitably tested. It's a very stable, secure, and reliable OS, which is why it's often used in running very critical networking services in enterprise environments. CentOS is one of the most important free Red Hat-based Linux server distributions out there at the moment. The most important Linux distribution families are Red Hat- and Debian-based Linux distributions. The main difference between them is the software selected and bundled together with the Linux kernel. Nowadays, one can choose between an insane amount of different Linux distributions, all designed for a special purpose and all with their own pros and cons. To make it complete, you need to bundle it together with all kinds of programs, which is then referred to as a distribution. As mentioned before, Linux is only the name of the kernel part, not a full working OS. Examples are popular internet services such as a web server, which presents websites to the user main servers for email communications and also database servers to store and deliver any kind of data. These are programs that run in the background of your Linux server, continuously waiting for external events to respond with some kind of action or information. One very important area in which Linux is very popular and is used heavily is managing many network services. Most of these programs are also open source, which means you can view the exact blueprint of how the program has been created and it can be changed by anyone. Most types of Linux OS do not cost anything, but provide thousands of programs and software to use completely free of charge. Linux is not the name of a specific and full working OS, but implements only the essential inner core of an OS, which is referred to as the kernel.
