Every single notebook or desktop or server is run by an Operating System - the low-level software which interacts with the computer hardware, including peripherals such as a mouse or a printer, together with any apps that are currently 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 OS. On a server, any app runs within the parameters specified by the OS as well - priority, physical memory, processing time, etc. This is valid for both standard site scripts and server-side software like a media server. When a virtual server is set up on a physical one, there can be two independent Operating Systems, referred to as guest OS and host OS, which means that you can set up a different software environment on a single machine.

Multiple OS in VPS Servers

In case you decide to acquire one of our VPS server packages, you will be able to opt for one of the three Linux distributions that we provide for the OS of the servers - CentOS, Ubuntu and Debian. They are among the most widespread and most reliable server OSs on the market and we offer them in order to give you a choice for the software environment of your machine in case that you wish to install some app with specific requirements in terms of the packages that have to be present on the web hosting server. We also offer three web hosting Control Panels and which one of them you could use will depend on the OS that you've chosen. We leave the option to change the server Operating System open, so when you want to use an app that requires an OS different from the one that's already present, we can always re-install the VPS. We can also keep the OS up-to-date weekly by installing any security updates that may be available.
