Every single PC or server is run by an Operating System - the low-level program that communicates with the hardware, including peripheral devices such as a mouse and a printer, and any applications that are present on your system. Any program input using a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the OS. On a web server, each application runs within the parameters established by the OS as well - priority, physical memory, processing time, etc. This goes for both standard website scripts and server-side software like a media server. When a virtual server is created on a physical one, there can be two different Operating Systems, called guest OS and host OS, so you'll be able to set up a different software environment on the very same machine.

Multiple OS in VPS Servers

In case you choose to purchase one of our VPS server plans, you'll be able to choose one of the three Linux releases that we supply for the OS of the servers - CentOS, Ubuntu and Debian. They are among the most preferred and most stable server OSs out there and we offer them in order to give you a choice for the software environment of your machine if you would like to install some application with precise requirements regarding the packages that need to be present on the web server. We also offer three hosting Control Panels and which one of them you can use depends on the OS that you've selected. We leave the chance to replace the server Operating System open, so when you want to use software that requires an OS different from the one you already have, we can always re-install the VPS. In addition, we can keep the OS up-to-date on a weekly basis by installing any security updates that may be released.
