Each personal computer or server is run by an Operating System - the low-level program that interacts with the hardware equipment, including peripherals such as a mouse and a printer, as well as any apps that are installed on your 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, each application runs within the parameters set by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard site scripts and server-side software like a media server. If a virtual server is created on a physical one, there can be two different Operating Systems, called guest OS and host OS, which means that you can set up a different software environment on the very same machine.

Multiple OS in VPS

If you choose to buy one of our virtual private server packages, you will be able to select one of the three Linux distributions that we supply for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most widespread and most stable server OSs out there and we offer them so that you have a choice for the software environment of your machine if you would like to install some app with particular requirements regarding the packages that have to be present on the server. We also offer three hosting Control Panels and which one of them you'll be able to use depends on the OS that you've picked. We leave the chance to change the server Operating System open, so if 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 Hosting

If you decide to buy one of our dedicated servers, you'll find three Operating Systems on the registration page as we want to give you a broader choice for the system environment on the server as different apps could have certain requirements. CentOS, Ubuntu and Debian include different modules developed by their huge support communities, so you can select any of these OSs and enjoy a reliable and secure web hosting service. Depending on your decision, you will also have different Control Panels to choose from. Of course, we can always change the Operating System if the one you have selected initially doesn't meet the requirements of the software which you want to run. We can also update your OS routinely to keep it as secure as possible through our Managed Services upgrade package.
