An Operating System is the software which communicates with the hardware of a PC and functions as the intermediary between apps and the hardware, including peripheral devices such as a printer, a mouse or a keyboard. When you run an application, it transmits requests to the OS through an API (Application Program Interface) and the contact is done through a command line or a Graphical User Interface (GUI). Just like a personal computer, web hosting servers also use an Operating System which functions as a host for all the software installed on them, including script applications or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be generated on a physical one, so you will be able to install a guest OS on it and have a different system environment in contrast with the physical server host Operating System.
Multiple OS in VPS Servers
If you select one of our VPS server packages, you'll have 3 different Operating Systems to pick from - CentOS, Debian and Ubuntu. They are all Linux releases and we offer them instead of offering just one OS, since the apps that you may want to run on the server could have specific requirements regarding the software environment. Each one of these three has certain pros with regard to the available plans that you could afterwards install, but what is common between them is the fact that they're very stable and reliable and have large communities which support them. The web hosting Control Panel choices for the VPS accounts depend on your OS choice, in order to provide you with more flexibility. In case you order the virtual server with one OS and you need another one later, our tech support team can easily reinstall the VPS with the new one in a matter of minutes. We also offer the option to keep the Operating System on your server up-to-date on a weekly basis.
Multiple OS in Dedicated Servers
In case you decide to purchase one of our dedicated servers, you'll find three Operating Systems on the order page because we want to give you a larger choice regarding the system environment on your machine as different applications could have particular requirements. CentOS, Ubuntu and Debian contain different modules developed by their huge support communities, so you can select each of these OSs and benefit from a stable and safe hosting service. Depending on your decision, you'll also have different Control Panels to choose from. Needless to say, we can always change the Operating System if the one you've selected at first does not meet the requirements of the software which you want to run. We can also update the OS on a regular basis in order to keep it as risk-free as possible through our Managed Services upgrade package.
