An Operating System is the fundamental software which manages a computer system. It takes care of the way the hardware behaves, the communication with peripheral devices including a monitor, a printer or a keyboard, the allocation of memory between the installed applications, and the prioritization of applications if multiple ones run simultaneously. Each program which is installed on a computer functions by sending requests to the OS for different services via an application program interface (API). The contact with the OS can be performed using a Graphical User Interface (GUI) or a command line. In the Internet hosting field, the OS is what commands a web hosting server and any software installed on it, which includes not only website scripts, but also every other application such as a VOIP or a game server. When there are virtual machines created, they employ a guest OS which runs on the server host OS.

Multiple OS in VPS Servers

In case you pick one of our VPS server packages, you'll have as many as 3 different Operating Systems to pick from - CentOS, Debian and Ubuntu. They are all Linux releases and we offer them instead of offering just one OS, since the applications that you might want to run on the server could have specific requirements about the software environment. Each of these three has some advantages with regard to the available plans that you could later on install, but what's common between them is that they're 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 provide you with 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 a matter of minutes. We also offer you the option to maintain the Operating System on your server up-to-date weekly.

Multiple OS in Dedicated Servers

In case you decide to get one of our dedicated servers, you shall find three Operating Systems on the order page as we want to give you a wider choice with regard to the system environment on your server as different applications can have certain requirements. CentOS, Ubuntu and Debian come with different modules developed by their large support communities, so you can select each of these OSs and benefit from a reliable and safe Internet hosting service. Depending on your decision, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you have selected at first does not meet the requirements of the software that you'd like to run. We can also update the OS on a regular basis to keep it as secure as possible with our Managed Services upgrade package.
