Every single personal computer or web server is run by an Operating System - the low-level program which interacts with the computer hardware, including peripheral devices such as a mouse or a printer, together with any applications that are currently installed on the system. Any program input through 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 app runs within the parameters set by the OS as well - priority, physical memory, processing time, and so on. This goes for both standard site scripts and server-side software like a media server. If a virtual server is generated on a physical one, there can be two separate Operating Systems, called guest OS and host OS, so you'll be able to set up a different software environment on the very same machine.

Multiple OS in Dedicated Hosting

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 price of your new web hosting server, but also because they are very secure and stable. Each of them is supported by a big community of developers, so you'll be given the option to choose from a myriad of software packages that you can 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 because the Control Panels that we offer run on particular OSs only and because we want to give you as much adaptability as possible, we offer a couple of OSs and multiple Control Panels. In case you choose a server with a certain Operating System, we will change it upon request in case it turns out that you need another one. We could also keep the OS updated on a weekly basis as part of our useful Managed Services upgrade.
