Every PC or web server is run by an Operating System - the low-level software that interacts with the hardware equipment, including peripherals such as a mouse or a printer, together with any applications that are 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 application runs within the parameters established by the OS as well - priority, physical memory, processing time, etc. This is valid for both standard Internet site scripts and server-side software like a media server. If a virtual server is generated on a physical one, there can be two separate Operating Systems, called guest OS and host OS, so that you will be able to set up a different software environment on the same machine.

Multiple OS in Dedicated Servers

In case you decide to get one of our dedicated servers, you shall find three Operating Systems on the order page because we want to give you a broader choice for the system environment on the machine as different apps may have certain requirements. CentOS, Ubuntu and Debian feature different modules developed by their large support communities, so you can select any of these OSs and take advantage of a stable and risk-free web hosting service. Depending on your choice, you will also have different Control Panels to choose from. Needless to say, we can always replace the Operating System if the one you have selected at first does not meet the requirements of the software that you'd like to run. We can also upgrade your OS on a regular basis in order to keep it as secure as possible with our Managed Services upgrade package.
