Every single notebook or desktop or server is run by an Operating System - the low-level software that communicates with the hardware, including peripherals such as a mouse or a printer, as well as 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 server, each application runs within the parameters specified by the OS as well - priority, physical memory, processing time, etc. This is valid for both standard website scripts and server-side software such as 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, which means that you will be able to set up a different software environment on the very same machine.
Multiple OS in VPS Servers
Our VPS server solutions come with three Linux distributions that you may pick from for the Operating System of your new web server - Debian, Ubuntu and CentOS. Aside from being cost-free, the OSs are very stable and safe and the reason to offer you all 3 of them is to make sure that you can run each app that you'd like, because different pieces of software have different requirements regarding the environment they work on. Each of the three OSs is supported by a vast community of developers who have created a large number of software packages which you can set up and use on your VPS. Based on the Operating System that you choose, you will also be able to choose between 3 different Control Panels to control your hosting content. Also, should you decide that you need a different OS, we could always reinstall the server with it. As an additional upgrade, we also offer you weekly updates of the Operating System for maximum stability and security.
Multiple OS in Dedicated Servers
In case you decide to obtain one of our dedicated servers, you shall find three Operating Systems on the registration page as we want to give you a wider choice regarding the system environment on your server as different apps may have certain requirements. CentOS, Ubuntu and Debian come with different modules developed by their huge support communities, so you can select each of these OSs and enjoy a reliable and risk-free web hosting service. Depending on your selection, you will also have different Control Panels to choose from. Needless to say, we can always change the Operating System in case the one you have selected at first doesn't meet the requirements of the software which you intend to run. We can also upgrade the OS on a regular basis in order to keep it as risk-free as possible through our Managed Services upgrade package.
