An Operating System is the software which communicates with the hardware of a computer and serves as the intermediary between all the applications and the hardware, which includes peripheral devices such as a printer, a computer mouse or a keyboard. When you run an application, it transmits requests to the OS using an API (Application Program Interface) and the interaction is done via a command line or a Graphical User Interface (GUI). Just like a personal computer, web hosting servers also have an Operating System which serves as a host for all the software installed on them, including script apps or server-side software such as a flash server, a VOIP server, etc. A virtual machine can be set up on a physical one, so you can install a guest OS on it and have a different system environment compared to the physical server host Operating System.

Multiple OS in VPS Servers

In case you select one of our VPS server plans, you will have as many as 3 different Operating Systems to select from - CentOS, Debian and Ubuntu. They're all Linux distributions and we offer them rather than offering just a single OS, as the apps that you may wish to run on the server could have specific requirements regarding the software environment. Each of these three has some advantages with regard to the available plans that you could afterwards install, but what is common between them is the fact that they're very secure and reliable and have huge communities that support them. The hosting Control Panel choices for the VPS accounts depend on your Operating System choice, in order to give you more flexibility. If you order the virtual server with one OS and you need a different 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 weekly.

Multiple OS in Dedicated Servers

If you decide to obtain one of our dedicated servers, you'll find three Operating Systems on the registration page as we want to give you a wider choice for the system environment on the server as different applications can have specific requirements. CentOS, Ubuntu and Debian feature different modules developed by their huge support communities, so you can select any of these OSs and take advantage of a reliable and secure Internet hosting service. Based on your decision, 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 have selected initially does not meet the requirements of the software which you intend to run. We can also upgrade the OS on a regular basis in order to keep it as secure as possible using our Managed Services upgrade package.
