An Operating System is the fundamental software that manages a computer. It handles the way your hardware operates, the communication with peripheral devices including a monitor, a printer or a keyboard, the allocation of memory between your applications, as well as the prioritization of apps if multiple ones run simultaneously. Each and every program that is installed on a desktop or a notebook functions by sending requests to the OS for various services via an application program interface (API). The interaction with the OS can be performed through a Graphical User Interface (GUI) or a command line. In the web hosting field, the OS is what commands a web server and all the software installed on it, which includes not only website scripts, but, in addition any other application such as a VOIP or a game server. If there are virtual machines created, they use a guest OS that is run on the server host OS.

Multiple OS in VPS Servers

If you pick one of our VPS server packages, you will have 3 different Operating Systems to select from - CentOS, Debian and Ubuntu. They are all Linux releases and we offer them rather than offering just one OS, since the applications that you may wish to run on the server may have specific requirements about the software environment. Each one of these three has some advantages regarding the available plans that you could eventually install, but what's common between them is the fact that they are very stable and reliable and have huge communities that support them. The web hosting Control Panel choices for the VPS accounts depend on your OS choice, in order to give you more flexibility. If 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 just a few minutes. We also offer the option to maintain 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'll find three Operating Systems on the registration page because we want to give you a broader choice regarding the system environment on the machine as different apps may have specific requirements. CentOS, Ubuntu and Debian contain different modules developed by their huge support communities, so you can select each of these OSs and enjoy a reliable and risk-free web hosting service. Depending on your decision, you'll also have different Control Panels to choose from. Of course, we can always change the Operating System if the one you have selected initially doesn't meet the requirements of the software that you intend to run. We can also update your OS on a regular basis in order to keep it as secure as possible with our Managed Services upgrade package.
