An Operating System is the software that interacts with the hardware of a computer and works as the intermediary between apps and the hardware, which includes peripherals such as a printer, a computer mouse or a keyboard. When you run an app, it sends requests to the OS through an API (Application Program Interface) and the communication is done through a command line or a Graphical User Interface (GUI). A lot like a personal computer, web servers also have an Operating System that functions as a host for any software installed on them, which includes script applications or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be set up on a physical one, so you will be able to install a guest OS on it and have a different system environment in contrast with the physical server host OS.

Multiple OS in VPS Servers

In case you decide to acquire one of our VPS server plans, you'll be able to choose one of the three Linux distributions which we supply for the Operating System of the servers - CentOS, Ubuntu and Debian. These are among the most widespread and most reliable server OSs available and we offer them so that you have a choice for the software environment of your machine in case that you intend to install some application with particular requirements in terms of the packages that should be present on the hosting server. We also offer three hosting Control Panels and which one of them you can use depends on the OS that you've selected. We leave the chance to change the server Operating System open, so if you want to use an application that requires an OS different from the one you already have, we can always reinstall the VPS. In addition, we can keep the OS up-to-date weekly by installing any security updates that may be available.

Multiple OS in Dedicated Servers

If you decide to purchase one of our dedicated servers, you shall find three Operating Systems on the registration page as we want to give you a wider choice with regard to the system environment on the machine as different applications could have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their large support communities, so you can select each of these OSs and enjoy a stable and safe web hosting service. Depending on your selection, you will 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 initially doesn't meet the requirements of the software that you'd like to run. We can also upgrade your OS regularly in order to keep it as secure as possible using our Managed Services upgrade package.
