Each and every desktop or notebook or server is run by an Operating System - the low-level software which communicates with the hardware, including peripherals such as a mouse and a printer, and any apps that are installed on the 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, any application runs within the parameters established 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. If 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
plans that we offer come with as many as three different Operating Systems to pick from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license fees, but they are also known as the most stable and secure OSs. We supply three different ones because each of them is backed by a separate community. The packages that you could add on your hosting server are different and this may 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 also depends on the OS that you will select. You may choose any of the three Operating Systems throughout the order procedure, but if needed, we can always install the server anew with a different one upon your request. As an optional service that you can add to the plan at any moment, we can update your OS regularly to keep it as risk-free as possible.
