Each and every personal computer or web server is run by an Operating System - the low-level software which communicates with the computer hardware, including peripherals such as a mouse or a printer, along with any apps that are currently 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 server, each and every app runs within the parameters defined 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 such as a media server. When a virtual server is set up on a physical one, there can be two different Operating Systems, named 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 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 100 % free so they won't increase the low price of your new web hosting server, but also because they are really stable and secure. Each one of them is backed up by a vast community of web developers, so you'll be given the option to choose from thousands of software packages that you may install on your server if the application that you intend to use has certain requirements. The Operating System will also determine what web hosting Control Panel you can use since the Control Panels that we offer are compatible with particular OSs only and since we would like to give you as much versatility 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 in case it turns out that you'll need alternative one. We will also keep the OS updated on a weekly basis as part of the additional Managed Services upgrade.
