Every PC or web server is run by an Operating System - the low-level program that interacts with the computer hardware, including peripheral devices such as a mouse and a printer, as well as any applications that are currently installed on the 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 web server, every single app runs within the parameters defined by the OS as well - priority, physical memory, processing time, etcetera. This is valid for both standard site scripts and server-side software like a media server. In case a virtual server is generated on a physical one, there can be two separate Operating Systems, referred to as guest OS and host OS, so that you can set up a different software environment on a single machine.

Multiple OS in VPS Servers

If you pick one of our VPS server packages, you'll have 3 different Operating Systems to choose from - CentOS, Debian and Ubuntu. They're all Linux releases and we offer them rather than offering just one OS, because the applications that you may wish to run on the server could have specific requirements regarding the software environment. Each one of the three has certain pros regarding the available plans that you can afterwards install, but what is common between them is the fact that they're really secure and reliable and have vast communities which support them. The internet hosting Control Panel alternatives for the VPS accounts depend on your Operating System choice, so as to provide you with more flexibility. If 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 couple of minutes. We also offer you the option to maintain the Operating System on your server up-to-date weekly.

Multiple OS in Dedicated Servers

In case you decide to purchase one of our dedicated servers, you'll find three Operating Systems on the order page since we want to give you a larger choice for the system environment on the machine as different applications could have specific requirements. CentOS, Ubuntu and Debian contain different modules developed by their vast support communities, so you can select any of these OSs and enjoy a reliable and secure web hosting service. Depending on your selection, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you've selected at first doesn't meet the requirements of the software which you intend to run. We can also upgrade the OS regularly in order to keep it as secure as possible using our Managed Services upgrade package.
