An Operating System is the software that communicates with the hardware of a computer system and functions as the intermediary between apps and the hardware, which includes peripherals such as a printer, a computer mouse or a keyboard. When you run software, it sends requests to the OS through an API (Application Program Interface) and the contact is done via a command line or a Graphical User Interface (GUI). Identical to a personal computer, web hosting servers also have an Operating System that serves as a host for the software installed on them, including script applications or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be generated on a physical one, so you could 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 purchase one of our virtual private server packages, you'll be able to select one of the three Linux releases which we offer for the Operating System of the servers - CentOS, Ubuntu and Debian. These are among the most popular and most stable server OSs available and we offer them so that you have a choice for the software environment of your machine if you intend to install some app with specific requirements in terms of the packages that need to be present on the server. We also offer three web hosting Control Panels and which one of them you can use will depend on the OS that you've chosen. We leave the option to change the server Operating System open, so if you want to use software that requires an OS different from the one you already have, we can always re-install 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
In case you decide to acquire one of our dedicated servers, you will find three Operating Systems on the order page since we want to give you a larger choice regarding the system environment on the machine as different applications could have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their vast support communities, so you can select each of these OSs and enjoy a stable and risk-free Internet hosting service. Based on your choice, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you have selected in the beginning doesn't meet the requirements of the software that you intend to run. We can also upgrade your OS routinely in order to keep it as secure as possible with our Managed Services upgrade package.
