An Operating System is the software that interacts with the hardware of a PC and is the intermediary between apps and the hardware, including peripherals such as a printer, a computer mouse or a keyboard. When you run an application, it sends 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). Similar to a personal computer, web hosting servers also use an Operating System that functions as a host for any software installed on them, which includes 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 in contrast with the physical server host OS.

Multiple OS in VPS Servers

In case you select one of our VPS server plans, you'll have as many as 3 different Operating Systems to choose from - CentOS, Debian and Ubuntu. They are all Linux distributions and we offer them rather than offering just a single OS, because the apps that you might want to run on the server could have specific requirements for the software environment. Each one of the three has some advantages in terms of the available plans that you could afterwards install, but what is common between them is that they are very secure and reliable and have vast communities that support them. The hosting Control Panel choices for the VPS accounts depend on your Operating System 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 technical support team can easily reinstall the VPS with the new one in a matter of minutes. We also offer you the option to keep the Operating System on your server up-to-date on a weekly basis.

Multiple OS in Dedicated Servers

If you decide to obtain one of our dedicated servers, you shall find three Operating Systems on the order page because we want to give you a wider choice with regard to the system environment on the server as different apps can have specific requirements. CentOS, Ubuntu and Debian feature different modules developed by their vast support communities, so you can select each of these OSs and benefit from a stable and risk-free hosting service. Based on your decision, 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 at first does not meet the requirements of the software that you would like to run. We can also upgrade the OS on a regular basis in order to keep it as risk-free as possible through our Managed Services upgrade package.
