Each PC or web server is run by an Operating System - the low-level software that interacts with the computer hardware, including peripheral devices such as a mouse or a printer, along with any applications that are 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 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. In case a virtual server is created on a physical one, there can be two different Operating Systems, called guest OS and host OS, so that you'll be able to set up a different software environment on a single machine.
Multiple OS in VPS Web Hosting
If you decide to purchase one of our virtual private server plans, you shall be able to choose one of the three Linux releases that we provide for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most popular and most stable server OSs available on the market and we offer them in order to give you a choice for the software environment of your machine if you need to install some application with particular requirements with regards to the packages that have to be present on the hosting server. We also offer three hosting Control Panels and which one of them you could use will depend on the OS that you've selected. We leave the possibility to replace 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 Hosting
If you decide to obtain one of our dedicated servers, you shall find three Operating Systems on the order page as we want to give you a broader choice with regard to the system environment on your machine as different applications can have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their huge support communities, so you can select any of these OSs and benefit from a stable and risk-free Internet hosting service. Based on your selection, you will also have different Control Panels to choose from. Of course, we can always replace the Operating System in case the one you've selected in the beginning doesn't meet the requirements of the software which you would like to run. We can also upgrade your OS regularly in order to keep it as risk-free as possible with our Managed Services upgrade package.
