Every desktop or notebook or web server is run by an Operating System - the low-level program which interacts with the hardware, including peripheral devices such as a mouse and a printer, and any applications that are present on your 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 OS. On a web server, each application runs within the parameters set by the OS as well - priority, physical memory, processing time, etcetera. This goes 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 different Operating Systems, called guest OS and host OS, so you will be able to set up a different software environment on the same machine.
Multiple OS in Dedicated Servers
The dedicated server plans that we offer come with as many as three different Operating Systems to select from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license taxes, but they’re also considered to be among the most stable and risk-free OSs. We offer three different ones because each of them is supported by a different community. The packages which you can add on your hosting server are different and this could matter if you need to install some piece of software with particular requirements about the hosting environment. In this light, the hosting Control Panel that you can select for the dedicated server is also determined by the OS that you'll select. You can choose any of the three Operating Systems throughout the order process, yet if necessary, we can always install the server once again with another one upon your request. As an additional service that you may add to the package at any moment, we can update your OS regularly so as to keep it as secure as possible.
