Every personal computer 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, as well as 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 OS. On a web server, any application runs within the parameters defined by the OS as well - priority, physical memory, processing time, etcetera. This goes for both standard site 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, referred to as guest OS and host OS, so that you can set up a different software environment on the same machine.
Multiple OS in Dedicated Servers Hosting
The dedicated server packages that we offer come with as many as three different Operating Systems to pick from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license taxes, but they’re also known as the most stable and secure OSs. We offer three different ones since each of them is supported by a separate community. The packages that you can add on your hosting server are different and this could matter in case you want to install some piece of software with specific requirements about the hosting environment. In this light, the web hosting Control Panel which you can select for the dedicated server also depends on the Operating System that you'll choose. You may choose any of the three Operating Systems throughout the order process, but if needed, we can always set up the server anew with a different one upon your request. As an optional service that you may add to the plan at any moment, we can update your OS on a regular basis so as to keep it as risk-free as possible.
