Each and every notebook or desktop or server is run by an Operating System - the low-level software which communicates with the hardware equipment, including peripheral devices such as a mouse or a printer, and any apps that are present 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 OS. On a web server, any app runs within the parameters established by the OS as well - priority, physical memory, processing time, etcetera. This is valid 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 independent Operating Systems, called guest OS and host OS, so you can set up a different software environment on the same machine.
Multiple OS in Dedicated Web Hosting
The dedicated server packages 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 charges, but they are also known as the most stable and secure OSs. We offer three different ones as each of them is backed by a different community. The packages that you could add on your server are different and this may matter in case you need to install some piece of software with specific requirements about the hosting environment. In this light, the hosting Control Panel which you can select for the dedicated server is also determined by the OS that you will pick. You can choose any of the three Operating Systems during the order process, yet if needed, we can always set up the server anew with an alternative one upon your request. As an optional service that you may add to the package any time, we can update your OS regularly in order to keep it as risk-free as possible.
