Every single PC or web server is run by an Operating System - the low-level program that communicates with the hardware, including peripherals such as a mouse or a printer, and any applications that are present 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 web server, each and every application runs within the parameters defined by the OS as well - priority, physical memory, processing time, etc. This is valid for both standard site scripts and server-side software like a media server. When a virtual server is set up on a physical one, there can be two independent Operating Systems, referred to as guest OS and host OS, which means that you can set up a different software environment on the same machine.

Multiple OS in VPS

In case you select one of our virtual private server plans, you'll have as many as three different Operating Systems to select from - CentOS, Debian and Ubuntu. They are all Linux releases and we offer them instead of offering just a single OS, since the applications that you may wish to run on the server could have specific requirements about the software environment. Each of the three has certain advantages regarding the available packages that you may later on install, but what is common between them is the fact that they are very stable and dependable and have vast communities that support them. The web hosting Control Panel alternatives for the VPS accounts depend on your Operating System choice, in order to provide you with more flexibility. When you order the virtual server with one OS and you need a different one later, our technical support team can easily reinstall the VPS with the new one in a couple of minutes. We also offer the option to maintain the Operating System on your server up-to-date on a weekly basis.

Multiple OS in Dedicated Hosting

If you decide to get one of our dedicated servers, you'll find three Operating Systems on the registration page since we want to give you a larger choice with regard to the system environment on your machine as different apps can have particular requirements. CentOS, Ubuntu and Debian feature different modules developed by their huge support communities, so you can select any of these OSs and benefit from a stable and risk-free hosting service. Based on your choice, you will also have different Control Panels to choose from. Of course, we can always replace the Operating System in case the one you have selected in the beginning doesn't meet the requirements of the software that you intend to run. We can also update your OS regularly to keep it as risk-free as possible with our Managed Services upgrade package.
