Each desktop or notebook or web server is run by an Operating System - the low-level program which communicates with the hardware, including peripheral devices such as a mouse and a printer, and any apps that are installed on your system. Any program input using a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the Operating System. On a web server, any application runs within the parameters specified by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard website scripts and server-side software like a media server. If a virtual server is created on a physical one, there can be two independent Operating Systems, referred to as guest OS and host OS, so that you'll be able to set up a different software environment on the same machine.

Multiple OS in Dedicated Servers Hosting

We offer three Operating Systems with our dedicated server plans - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they are totally free and they will not increase the price of your new hosting server, but also because they are exceptionally stable and secure. Each of them is backed up by a vast community of developers, so you'll be given the option to choose from thousands of software packages that you could install on your server if the app that you would like to work with has certain requirements. The Operating System will also determine what hosting Control Panel you can use since the Control Panels that we offer run on particular OSs only and because we want to give you as much freedom as possible, we offer a couple of OSs and multiple Control Panels. In case you choose a server with a certain Operating System, we could change it upon request if it turns out that you need another one. We could also keep your OS updated weekly as a part of the optional Managed Services upgrade.
