Each and every personal computer or server is run by an Operating System - the low-level software that communicates with the computer hardware, including peripherals such as a mouse or a printer, together with any apps that are present 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, each app runs within the parameters set by the OS as well - priority, physical memory, processing time, etcetera. This is valid for both standard Internet site scripts and server-side software like a media server. When a virtual server is set up on a physical one, there can be two independent Operating Systems, referred to as guest OS and host OS, so that you can set up a different software environment on the very same machine.

Multiple OS in Dedicated Servers

We offer three Operating Systems with our dedicated server solutions - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they are freely available and they won't increase the low price of your new hosting server, but also because they are extremely stable and secure. Each of them is backed up by a huge community of developers, so you'll be given the option to choose from a myriad of software packages that you may install on your server in case the app that you intend to work with has certain requirements. The Operating System will also determine what web hosting Control Panel you can use as the Control Panels that we offer are compatible with particular OSs only and since we want to give you as much freedom as possible, we offer several OSs and multiple Control Panels. If you choose a server with a given OS, we could change it upon request if it turns out that you will need a different one. We can also keep the OS updated on a weekly basis as part of our additional Managed Services upgrade.
