Each personal computer or server is run by an Operating System - the low-level software which interacts with the hardware, including peripherals such as a mouse or a printer, and any apps that are currently installed on the 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 OS. On a web server, each and every application runs within the parameters set by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard Internet site scripts and server-side software like 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 you will be able to set up a different software environment on a single machine.

Multiple OS in Dedicated Servers

In case you decide to buy one of our dedicated servers, you shall find three Operating Systems on the order page because we want to give you a wider choice regarding the system environment on your server as different applications may have particular requirements. CentOS, Ubuntu and Debian come with different modules developed by their huge support communities, so you can select each of these OSs and enjoy a reliable and secure hosting service. Depending on your choice, you will also have different Control Panels to choose from. Of course, we can always replace the Operating System if the one you've selected initially doesn't meet the requirements of the software which you want to run. We can also upgrade the OS regularly in order to keep it as risk-free as possible with our Managed Services upgrade package.
