Every desktop or notebook or server is run by an Operating System - the low-level program that interacts with the hardware equipment, including peripherals such as a mouse or a printer, as well as 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 app 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 created on a physical one, there can be two independent Operating Systems, named guest OS and host OS, so that you will be able to set up a different software environment on the very same machine.
Multiple OS in Dedicated Servers
The dedicated server packages that we offer come with as many as three different Operating Systems to choose from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license taxes, but they’re also regarded as the most reliable and risk-free OSs. We supply three different ones since each one of them is backed by a separate community. The packages that you can add on your server are different and this could matter in case you need to install some piece of software with specific requirements for the hosting environment. In this light, the internet hosting Control Panel which you can select for the dedicated server also depends on the OS that you will pick. You may choose any of the three Operating Systems during the order process, yet if necessary, we can always install the server once again with a different one upon your request. As an additional service that you can add to the package at any time, we can update your OS on a regular basis in order to keep it as risk-free as possible.
