An Operating System is the basic software which manages a computer system. It takes care of the way the hardware behaves, the communication with peripherals such as a monitor, a printer or a keyboard, the allocation of memory between various applications, and the prioritization of applications when multiple ones run at once. Every program that is installed on a notebook or a desktop works by sending requests to the OS for various services by using an application program interface (API). The contact with the OS can be achieved through a Graphical User Interface (GUI) or a command line. In the web hosting field, the OS is what commands a web hosting server as well as any software installed on it, which includes not only website scripts, but also any other application for instance a VOIP or a game server. When there're virtual machines created, they work with a guest OS which is run on the server host OS.
Multiple OS in VPS Servers
If you decide to buy one of our VPS server packages, you shall be able to choose one of the three Linux distributions that we offer for the OS of the servers - CentOS, Ubuntu and Debian. They are among the most preferred and most dependable server OSs available and we offer them in order to give you a choice for the software environment of your machine if you intend to install some application with particular requirements regarding the packages that should be present on the web server. We also offer three internet hosting Control Panels and which one of them you may use will depend on the OS that you've selected. We leave the possibility to change the server Operating System open, so if you want to use an application that requires an OS different from the one you have, we can always re-install the VPS. We can also keep the OS up-to-date on a weekly basis by installing all the security updates that may be available.
Multiple OS in Dedicated Servers
In case you decide to acquire one of our dedicated servers, you will find three Operating Systems on the order page as we want to give you a larger choice with regard to the system environment on your server as different applications can have specific requirements. CentOS, Ubuntu and Debian feature different modules developed by their large support communities, so you can select any of these OSs and benefit from a stable and secure Internet hosting service. Based on your selection, you'll also have different Control Panels to choose from. Of course, we can always change the Operating System if the one you have selected initially doesn't meet the requirements of the software which you would like to run. We can also upgrade the OS routinely in order to keep it as secure as possible through our Managed Services upgrade package.
