Each and every PC or server is run by an Operating System - the low-level software that communicates with the computer hardware, including peripherals such as a mouse and a printer, together with any applications that are installed on the system. Any program input using 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 server, any application runs within the parameters defined by the OS as well - priority, physical memory, processing time, etc. This goes for both standard Internet site scripts and server-side software like a media server. In case a virtual server is generated on a physical one, there can be two separate Operating Systems, called guest OS and host OS, so you will be able to set up a different software environment on the very same machine.
Multiple OS in VPS Servers
In case you select one of our VPS server plans, you'll have 3 different Operating Systems to choose from - CentOS, Debian and Ubuntu. They are all Linux releases and we offer them instead of offering just a single OS, since the applications that you might choose to run on the server could have specific requirements regarding the software environment. Each one of these three has some pros regarding the available plans that you can afterwards install, but what is common between them is that they are very stable and dependable and have huge communities which support them. The web hosting Control Panel choices for the VPS accounts depend on your OS choice, so as to provide you with more flexibility. In case you order the virtual server with one OS and you need another one later, our technical support team can easily reinstall the VPS with the new one in just a few minutes. We also offer the option to keep the Operating System on your server up-to-date weekly.
Multiple OS in Dedicated Servers
If you decide to purchase one of our dedicated servers, you will find three Operating Systems on the registration page since we want to give you a broader choice for the system environment on the machine as different apps could have particular 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 reliable and secure web hosting service. Depending on your selection, you will also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you've selected initially doesn't 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 secure as possible with our Managed Services upgrade package.
