An Operating System is the software that interacts with the hardware of a computer and is the intermediary between the installed applications and the hardware, which includes peripherals such as a printer, a computer mouse or a keyboard. When you run an app, it sends requests to the OS through an API (Application Program Interface) and the interaction is done through a command line or a Graphical User Interface (GUI). Just like a personal computer, web servers also use an Operating System which acts as a host for all of the software installed on them, including script applications or server-side software such as a flash server, a VOIP server, and many others. A virtual machine can be created on a physical one, so you'll be able to install a guest OS on it and have a different system environment in contrast to the physical server host Operating System.

Multiple OS in VPS

In case you select one of our virtual private server plans, you will have three different Operating Systems to pick from - CentOS, Debian and Ubuntu. They're all Linux releases and we offer them instead of offering just one OS, since the apps that you may want to run on the server could have specific requirements about the software environment. Each of these three has some advantages regarding the available plans that you can eventually install, but what is common between them is the fact that they're really stable and dependable and have huge communities that support them. The web hosting Control Panel alternatives for the VPS accounts depend on your OS choice, in order to give you more flexibility. If you order the virtual server with one OS and you need another one later, our technical support team can easily reinstall the VPS with the new one in a couple of minutes. We also offer you the option to maintain the Operating System on your server up-to-date weekly.
