An Operating System is the fundamental software that controls a computer system. It controls the way the hardware behaves, the communication with peripherals for instance a monitor, a printer or a keyboard, the allocation of memory between the installed applications, plus the prioritization of applications in case several run at the same time. Every program which is installed on a PC functions by sending requests to the OS for various services via an application program interface (API). The communication with the OS can be achieved using a Graphical User Interface (GUI) or a command line. In the hosting field, the Operating System is what controls a server and all of the software installed on it, which includes not only website scripts, but, in addition every other application for example a VOIP or a game server. In case there're virtual machines created, they work with a guest OS which is run on the server host OS.
Multiple OS in VPS Servers
Our VPS server plans come with three Linux distributions that you may pick from for the Operating System of your new hosting server - Debian, Ubuntu and CentOS. Apart from being free, the OSs are really stable and risk-free and the reason to offer the three of them is to make sure that you'll be able to run any kind of app that you'd like, as different pieces of software may have different requirements with regards to the environment they work on. Each of the three OSs is supported by a huge community of web developers who have created a large number of software packages that you can set up and use on your VPS. Depending on the Operating System which you pick, you will also be able to choose between 3 different Control Panels to control your web hosting content. Needless to say, in case you decide that you need a new OS, we can always reinstall the server with it. As an optional upgrade, we also offer weekly updates of the OS for max stability and security.
Multiple OS in Dedicated Servers
In case you decide to acquire one of our dedicated servers, you will find three Operating Systems on the registration page since we want to give you a wider choice with regard to the system environment on your machine as different applications can have specific requirements. CentOS, Ubuntu and Debian include different modules developed by their vast support communities, so you can select any of these OSs and benefit from a stable and risk-free Internet hosting service. Depending on your selection, you'll also have different Control Panels to choose from. Of course, we can always change the Operating System if the one you've selected initially does not meet the requirements of the software which you would like to run. We can also update the OS routinely in order to keep it as secure as possible using our Managed Services upgrade package.
