Every single personal computer or web server is run by an Operating System - the low-level program which interacts with the hardware, including peripheral devices such as a mouse or a printer, and any apps that are installed on the system. Any program input through a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the Operating System. On a server, any app runs within the parameters specified by the OS as well - priority, physical memory, processing time, etcetera. This is valid for both standard website scripts and server-side software like a media server. When a virtual server is set up on a physical one, there can be two separate Operating Systems, called guest OS and host OS, so that you will be able to set up a different software environment on the very same machine.

Multiple OS in VPS Web Hosting

If you choose to purchase one of our virtual private server packages, you shall be able to choose one of the three Linux releases which we provide for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most preferred and most reliable server OSs available on the market and we offer them in order to give you a choice for the software environment of your machine if you need to install some application with precise requirements regarding the packages that must be present on the web server. We also offer three internet hosting Control Panels and which one of them you can use depends on the OS that you've chosen. We leave the chance to change the server Operating System open, so if you want to use an app that requires an OS different from the one you have, we can always re-install the VPS. We can also keep the OS up-to-date weekly by installing all of the security updates that may be available.
