An Operating System is the low-level software that controls a PC. It controls how the hardware operates, the communication with peripherals such as a monitor, a printer or a keyboard, the allocation of memory between applications, plus the prioritization of applications in case multiple ones run simultaneously. Each and every program which is installed on a PC functions by sending requests to the OS for various services using an application program interface (API). The contact with the OS can be done via a Graphical User Interface (GUI) or a command line. In the web hosting field, the Operating System is what runs a server together with any software installed on it, which includes not only website scripts, but, in addition every other application for example a VOIP or a game server. If there're virtual machines created, they employ a guest OS which is run on the server host OS.

Multiple OS in VPS Servers

In case you decide to go for one of our VPS server plans, you'll be able to opt for one of the three Linux releases that we offer for the OS of the servers - CentOS, Ubuntu and Debian. They are among the most widespread 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 wish to install some application with specific requirements in terms of the packages that have to be present on the web hosting server. We also offer three internet hosting Control Panels and which one of them you'll be able to use will depend on the OS that you have selected. We leave the option to replace the server Operating System open, so if you want to use an application that requires an OS different from the one you have, we can always reinstall the VPS. In addition, we can keep the OS up-to-date weekly by installing all of the security updates which may be released.

Multiple OS in Dedicated Servers

In case you decide to buy one of our dedicated servers, you'll find three Operating Systems on the registration page as we want to give you a wider choice regarding the system environment on your server as different applications may have particular requirements. CentOS, Ubuntu and Debian include different modules developed by their huge support communities, so you can select any of these OSs and take advantage of a reliable and secure hosting service. Depending on your choice, you'll also have different Control Panels to choose from. Of course, we can always change the Operating System in case the one you've selected at first does not meet the requirements of the software that you want to run. We can also update the OS regularly to keep it as secure as possible using our Managed Services upgrade package.
