An Operating System is the basic software which controls a PC. It handles how your hardware functions, the communication with peripherals like a monitor, a printer or a keyboard, the allocation of memory between apps, plus the prioritization of apps if multiple ones run at once. Each and every program that is installed on a computer system works by sending requests to the OS for different services using an application program interface (API). The communication with the OS can be achieved via a Graphical User Interface (GUI) or a command line. In the hosting field, the Operating System is what runs a server as well as all of the software installed on it, which includes not only website scripts, but also any other application for instance a VOIP or a game server. When there're virtual machines created, they employ a guest OS that is run on the server host OS.
Multiple OS in VPS Servers
Our VPS server plans come with three Linux distributions which you could pick from for the Operating System of your new hosting server - Debian, Ubuntu and CentOS. In addition to being totally free, the OSs are extremely stable and protected and the main reason to offer the three of them is to make sure that you'll be able to run any application that you would like, as different pieces of software could have different requirements with regards to the environment they work on. Each one of the three OSs is backed by a large community of developers who have developed thousands of software packages that you can install and use on your VPS. In accordance with the Operating System that you select, you will also be able to choose between three different Control Panels to take care of your website hosting content. Needless to say, should you decide that you need a different OS, we could always reinstall the server with it. As an additional upgrade, we also offer weekly updates of the Operating System for optimum stability and security.
Multiple OS in Dedicated Servers
If you decide to obtain one of our dedicated servers, you'll find three Operating Systems on the registration page since we want to give you a broader choice with regard to the system environment on the machine as different apps could have particular 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 reliable and secure hosting service. Based on your choice, you will also have different Control Panels to choose from. Needless to say, we can always replace the Operating System if the one you've selected at first does not meet the requirements of the software that you intend to run. We can also update your OS routinely to keep it as risk-free as possible through our Managed Services upgrade package.
