Every single desktop or notebook or web 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, together with any applications that are installed on your 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 Operating System. On a web server, every single app runs within the parameters established 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. If a virtual server is set up on a physical one, there can be two separate Operating Systems, named guest OS and host OS, so that you can set up a different software environment on the very same machine.
Multiple OS in VPS Hosting
Our virtual private server packages come with three Linux releases which you could pick from for the Operating System of your new server - Debian, Ubuntu and CentOS. Apart from being absolutely free, the OSs are really stable and risk-free and the key reason to offer you all three of them is to make sure that you can run each application that you would like, because different pieces of software have different requirements with regards to the environment they can be used on. Each of the three OSs is supported by a huge community of developers who have produced many hundreds of software packages which you can set up and use on your VPS. In accordance with the Operating System which you choose, you will also be able to select between three different Control Panels to control your hosting content. Needless to say, if you decide that you need a new OS, we can always re-install the server with it. As an optional upgrade, we also provide weekly updates of the OS for maximum stability and security.
Multiple OS in Dedicated Web Hosting
We offer three Operating Systems with our dedicated server packages - CentOS, Ubuntu and Debian. They are all different Linux distributions and we offer them not only because they're completely free so they won't increase the low price of your new web hosting server, but also because they are exceptionally secure and stable. Each of them is backed up by a huge community of developers, so you will be able to choose from countless software packages that you can install on your server in case the application that you want to employ has certain requirements. The Operating System will also determine what web hosting Control Panel you can use as the Control Panels that we offer are compatible with particular OSs only and since we would like to give you as much freedom as possible, we offer several OSs and multiple Control Panels. If you choose a server with a certain OS, we can change it upon request in case it turns out that you will need another one. We could also keep your OS updated weekly as part of our useful Managed Services upgrade.
