Each and every personal computer or server is run by an Operating System - the low-level software which interacts with the computer hardware, including peripherals such as a mouse or a printer, and any applications that are installed on the system. Any program input through a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the OS. On a server, any application runs within the parameters defined by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard website scripts and server-side software such as a media server. When a virtual server is set up on a physical one, there can be two independent Operating Systems, named guest OS and host OS, which means that you can set up a different software environment on a single machine.

Multiple OS in VPS Servers

If you choose to purchase one of our VPS server packages, you will be able to pick one of the three Linux distributions that we offer for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most popular and most reliable server OSs available and we offer them in order to give you a choice for the software environment of your machine in case that you wish to install some application with precise requirements with regards to the packages that must be present on the hosting server. We also offer three hosting Control Panels and which one of them you may use will depend on the OS that you've picked. We leave the possibility to change the server Operating System open, so if you want to use software 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 weekly by installing any security updates which may be available.

Multiple OS in Dedicated Servers

If you decide to acquire one of our dedicated servers, you shall find three Operating Systems on the registration page because we want to give you a broader choice regarding the system environment on your server as different applications could have certain requirements. CentOS, Ubuntu and Debian contain different modules developed by their large support communities, so you can select any of these OSs and enjoy a stable and secure web hosting service. Depending on your decision, you will also have different Control Panels to choose from. Needless to say, we can always change the Operating System if the one you have selected in the beginning does not meet the requirements of the software that you intend to run. We can also upgrade the OS on a regular basis in order to keep it as risk-free as possible with our Managed Services upgrade package.
