Each and every PC or web server is run by an Operating System - the low-level software that communicates with the hardware equipment, including peripheral devices such as a mouse and a printer, and any apps that are installed 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 Operating System. On a web server, each and every app runs within the parameters established by the OS as well - priority, physical memory, processing time, etcetera. This is valid for both standard site scripts and server-side software like a media server. When a virtual server is created on a physical one, there can be two different Operating Systems, referred to as guest OS and host OS, which means that you'll be able to set up a different software environment on a single machine.
Multiple OS in Dedicated Web Hosting
The dedicated servers
we offer can be set up with three different Operating Systems because we want to offer you more flexible solutions that will let you install and run any kind of web software whatever its system requirements. The choices are CentOS, Debian and Ubuntu and these three OSs are some of the most dependable and risk-free ones, not mentioning that they do not have any kind of license charges. All three have numerous developers that have created numerous software packages that you can install and use on your hosting server. We also offer three hosting Control Panels and which one you can use is determined by the Operating System that you select when you register. In case you need some other OS subsequently, it won't be a problem since we can always reinstall your machine. With our Managed Services package we could also keep your OS secure by upgrading it on a weekly basis with all patches which are available for it.
