An Operating System is the fundamental software that controls a computer system. It takes care of how your hardware behaves, the communication with peripherals for instance a monitor, a printer or a keyboard, the allocation of memory between your applications, and the prioritization of apps when several run concurrently. Every program that is installed on a desktop or a laptop works by sending requests to the OS for different services by using an application program interface (API). The communication with the OS can be performed using a Graphical User Interface (GUI) or a command line. In the web hosting field, the OS is what controls a web server along with any software installed on it, which includes not only website scripts, but, in addition any other application for example a VOIP or a game server. If there're virtual machines created, they employ a guest OS which runs on the server host OS.

Multiple OS in VPS

If you select one of our virtual private server plans, you will have 3 different Operating Systems to pick from - CentOS, Debian and Ubuntu. They are all Linux distributions and we offer them rather than offering just one OS, since the apps that you might want to run on the server could have specific requirements regarding the software environment. Each of these three has certain advantages regarding the available packages that you could later on install, but what is common between them is the fact that they are really stable and reliable and have vast communities that support them. The web hosting Control Panel choices for the VPS accounts depend on your Operating System choice, so as to give you more flexibility. In case you order the virtual server with one OS and you need a different one later, our tech support team can easily reinstall the VPS with the new one in just a few minutes. We also offer the option to keep the Operating System on your server up-to-date on a weekly basis.

Multiple OS in Dedicated Hosting

In case you decide to acquire one of our dedicated servers, you'll find three Operating Systems on the registration page as we want to give you a broader choice for the system environment on your server as different applications can have certain requirements. CentOS, Ubuntu and Debian come with different modules developed by their vast support communities, so you can select any of these OSs and enjoy a reliable 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 in case the one you have selected at first does not meet the requirements of the software which you'd like to run. We can also upgrade the OS routinely in order to keep it as risk-free as possible using our Managed Services upgrade package.
