Every single notebook or desktop or server is run by an Operating System - the low-level program which interacts with the computer hardware, including peripherals such as a mouse or a printer, as well as any apps that are currently 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, each app runs within the parameters defined by the OS as well - priority, physical memory, processing time, etcetera. This is valid for both standard Internet site scripts and server-side software such as a media server. If a virtual server is set up on a physical one, there can be two separate Operating Systems, named guest OS and host OS, so you can set up a different software environment on the same machine.

Multiple OS in VPS Servers

If you decide to purchase one of our VPS server packages, you'll be able to pick one of the three Linux distributions which we supply for the Operating System of the servers - CentOS, Ubuntu and Debian. They are among the most widespread and most dependable server OSs available and we offer them in order to give you a choice for the software environment of your machine if you intend to install some app with precise requirements with regards to the packages that have to be present on the server. We also offer three web hosting Control Panels and which one of them you can use will depend on the OS that you have chosen. We leave the option to change the server Operating System open, so when you want to use an app that requires an OS different from the one you have, we can always re-install the VPS. In addition, we can keep the OS up-to-date weekly by installing all the security updates which may be available.

Multiple OS in Dedicated Servers

The dedicated server plans that we offer come with three different Operating Systems to choose from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they are also considered to be among the most reliable and secure OSs. We supply three different ones since each one of them is backed by a different community. The packages that you can add on your server are different and this could matter if you want to install some piece of software with specific requirements regarding the hosting environment. In this light, the hosting Control Panel which you can select for the dedicated server is also determined by the Operating System that you will pick. You can select any of the three Operating Systems during the order process, but if necessary, we can always install the server once again with an alternative one upon your request. As an optional service that you may add to the package whenever you want, we can update your OS regularly to keep it as secure as possible.
