Each and every personal computer or server is run by an Operating System - the low-level software which interacts with the computer hardware, including peripherals such as a mouse or a printer, along with any apps that are currently installed 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 Operating System. On a web server, any application 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. When a virtual server is generated on a physical one, there can be two different Operating Systems, referred to as guest OS and host OS, so you'll be able to set up a different software environment on a single machine.
Multiple OS in VPS Web Hosting
Our virtual private server packages include three Linux releases that you can select from for the Operating System of your new web server - Debian, Ubuntu and CentOS. Aside from being totally free, the OSs are really stable and safe and the main reason to offer you all three of them is to ensure that you can run every app that you would like, since different pieces of software have different requirements for the environment they work on. Each of the three OSs is backed by a huge community of developers who have generated thousands of software packages that you can install and use on your VPS. In accordance with the Operating System which you choose, you will also be able to choose between three different Control Panels to control your website hosting content. Needless to say, should you decide that you need a different OS, we can always re-install the server with it. As an optional upgrade, we also offer weekly updates of the OS for maximum stability and security.
Multiple OS in Dedicated Servers Hosting
We offer three Operating Systems with our dedicated server packages - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they're cost-free so they will not increase the cost of your new web server, but also because they are exceptionally stable and secure. Each one of them is backed up by a vast community of developers, so you will be able to choose from a myriad of software packages that you could install on your server if the app that you would like to use has specific requirements. The Operating System will also determine what web hosting Control Panel you can use because the Control Panels that we offer are compatible with specific OSs only and since we want to give you as much flexibility as possible, we offer multiple OSs and multiple Control Panels. In case you get a server with a given Operating System, we will change it upon request in case it turns out that you'll need a different one. We can also keep the OS updated weekly as part of our useful Managed Services upgrade.
