An Operating System is the software which interacts with the hardware of a computer and functions as the intermediary between applications and the hardware, which includes peripheral devices such as a printer, a mouse or a keyboard. When you run software, it transfers requests to the OS through an API (Application Program Interface) and the communication is done through a command line or a Graphical User Interface (GUI). A lot like a personal computer, hosting servers also use an Operating System which functions as a host for the software installed on them, including script apps or server-side software such as a flash server, a VOIP server, etcetera. A virtual machine can be set up on a physical one, so you'll be able to install a guest OS on it and have a different system environment in contrast with the physical server host OS.
Multiple OS in VPS Hosting
In case you decide to acquire one of our virtual private server packages, you'll be able to select one of the three Linux releases which we provide for the OS of the servers - CentOS, Ubuntu and Debian. They're among the most widely used and most dependable server OSs out there and we offer them so that you have a choice for the software environment of your machine in case that you would like to install some app with precise requirements with regards to the packages that need to be present on the web server. We also offer three web hosting Control Panels and which one of them you can use will depend on the OS that you have selected. We leave the possibility to change the server Operating System open, so when you want to use an application that requires an OS different from the one that's already present, we can always reinstall the VPS. We can also keep the OS up-to-date on a weekly basis by installing any security updates which may be released.
Multiple OS in Dedicated Web Hosting
If you decide to purchase one of our dedicated servers, you'll find three Operating Systems on the order page as we want to give you a wider choice with regard to the system environment on the machine as different apps could have particular requirements. CentOS, Ubuntu and Debian include different modules developed by their huge support communities, so you can select any of these OSs and benefit from a reliable and risk-free hosting service. Based on your choice, you will also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you've selected at first doesn't meet the requirements of the software which you intend to run. We can also upgrade the OS regularly to keep it as secure as possible using our Managed Services upgrade package.
