An Operating System is the fundamental software that controls a computer. It handles how the hardware functions, the communication with peripheral devices for instance 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 that is installed on a computer system functions by sending requests to the OS for various services by using an application program interface (API). The communication with the OS is possible using a Graphical User Interface (GUI) or a command line. In the hosting world, the OS is what controls a web hosting server as well as 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. When there're virtual machines created, they work with a guest OS which runs on the server host OS.
Multiple OS in VPS Hosting
Our virtual private server
plans come with three Linux distributions that you could pick from for the Operating System of your new server - Debian, Ubuntu and CentOS. In addition to being cost-free, the OSs are very stable and safe and the primary reason to offer the 3 of them is to ensure that you will be able to run any app that you would like, since different pieces of software could have different requirements regarding the environment they can be used on. Each one of the three OSs is backed by a vast community of developers who have developed a large number of software packages which you can set up and use on your VPS. Based on the Operating System that you choose, you will also be able to select between three different Control Panels to handle your website hosting content. Needless to say, if you decide that you need a new OS, we could always re-install the server with it. As an additional upgrade, we also offer weekly updates of the Operating System for maximum stability and security.
Multiple OS in Dedicated Web Hosting
In case you decide to obtain one of our dedicated servers
, you will find three Operating Systems on the registration page since we want to give you a wider choice regarding the system environment on the server as different apps could have specific requirements. CentOS, Ubuntu and Debian include different modules developed by their vast support communities, so you can select any of these OSs and benefit from 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 in the beginning doesn't meet the requirements of the software which you intend to run. We can also upgrade your OS routinely to keep it as secure as possible through our Managed Services upgrade package.
