Virtualization

Virtualization is the technology used to create multiple simulated environments on a single physical system. Each environment is separated from one another and could fully utilize the resources dedicated to it. A virtual machine is an operating system that runs on top of a host operating system.

The physical host operating system, equipped with a hypervisor, control resources allocated to the virtual environment, which is called the guest system. The applications running in the virtual operating system are not aware that they are running on top of a virtualized machine. They instead behave exactly the same way they would on a physical system.

For the average user, virtualization enables them to be able to run applications that are built for an OS different from the physical OS they have. Users don’t have to worry about rebooting or switching to another computer in order to install an application. Some common applications used to create virtualized environments are VirtualBox, Docker, and VMWare.

From a network administrator’s point of view, virtualization helps them segment a larger system into smaller parts, each fully isolated from one another. This helps them serve a large number of clients better and easily adapt their system to a client’s specific needs. Virtualization also acts as a security feature that keeps running programs in their separate containers, preventing one from making changes to another.

Thanks to virtualization, users can enjoy competitive prices and more control over their server. You can deploy an OS of your choice in a matter of minutes, or replicate a working OS how many times you want, without the hassle of installation and configuration from the beginning. In case of disaster, virtualized servers could be recovered easily with a few simple steps. For users who require full control over their server so that they can install necessary programs to run their application, a dedicated virtualized server is highly recommended.
