An Operating System is the low-level software which manages a computer. It controls how the hardware operates, the communication with peripheral devices such as a monitor, a printer or a keyboard, the allocation of memory between various applications, along with the prioritization of apps in case multiple ones run at the same time. Any program that is installed on a laptop or a desktop operates by sending requests to the OS for different services using an application program interface (API). The contact with the OS can be achieved via a Graphical User Interface (GUI) or a command line. In the Internet hosting world, the Operating System is what controls a web server along with all of the software installed on it, which includes not only website scripts, but also every other application for example a VOIP or a game server. In case there're virtual machines created, they use a guest OS that is run on the server host OS.

Multiple OS in VPS Servers

In case you choose one of our VPS server packages, you'll have 3 different Operating Systems to choose from - CentOS, Debian and Ubuntu. They are all Linux distributions and we offer them instead of offering just a single OS, because the applications that you might choose to run on the server could have specific requirements regarding the software environment. Each of the three has certain advantages with regard to the available packages that you could eventually install, but what is common between them is the fact that they're really stable and reliable and have huge communities which support them. The hosting Control Panel choices for the VPS accounts depend on your OS choice, in order to give you more flexibility. When you order the virtual server with one OS and you need a different one later, our technical support team can easily reinstall the VPS with the new one in a couple of minutes. We also offer you the option to keep the Operating System on your server up-to-date on a weekly basis.

Multiple OS in Dedicated Servers

If you decide to purchase one of our dedicated servers, you will find three Operating Systems on the order page since we want to give you a broader choice regarding the system environment on the server as different applications can have particular requirements. CentOS, Ubuntu and Debian feature different modules developed by their vast support communities, so you can select any of these OSs and enjoy a stable and safe web hosting service. Depending on your selection, you'll also have different Control Panels to choose from. Needless to say, we can always change the Operating System if the one you have selected in the beginning doesn't meet the requirements of the software which you intend to run. We can also upgrade the OS on a regular basis in order to keep it as risk-free as possible with our Managed Services upgrade package.
