An Operating System is the software which communicates with the hardware of a computer system and functions as the intermediary between all the applications and the hardware, including peripherals such as a printer, a computer mouse or a keyboard. When you run software, it sends requests to the OS using an API (Application Program Interface) and the communication is done through a command line or a Graphical User Interface (GUI). Identical to a personal computer, web servers also have an Operating System that serves as a host for any software installed on them, which includes script apps or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be created on a physical one, so you can install a guest OS on it and have a different system environment in contrast with the physical server host Operating System.
Multiple OS in VPS Servers
Our VPS server packages include three Linux releases which you could pick from for the Operating System of your new hosting server - Debian, Ubuntu and CentOS. Apart from being free, the OSs are really stable and safe and the reason to offer you the 3 of them is to make sure that you'll be able to run any app that you'd like, because different pieces of software may have different requirements for the environment they can be used on. Each one of the three OSs is supported by a vast community of developers who have generated thousands of software packages that you can set up and use on your VPS. In accordance with the Operating System that you pick, you will also be able to select between 3 different Control Panels to take care of your web hosting content. Needless to say, should you decide that you need a different OS, we can always re-install the server with it. As an optional upgrade, we also offer you weekly updates of the OS for max stability and security.
Multiple OS in Dedicated Servers
In case you decide to purchase one of our dedicated servers, you shall find three Operating Systems on the registration page because we want to give you a broader choice with regard to the system environment on the machine as different applications may 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 web hosting service. Based on your selection, you will also have different Control Panels to choose from. Of course, we can always change the Operating System in case the one you have selected initially doesn't meet the requirements of the software which you'd like to run. We can also upgrade the OS routinely to keep it as secure as possible using our Managed Services upgrade package.
