An Operating System is the software which communicates with the hardware of a computer system and is the intermediary between the installed 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 via a command line or a Graphical User Interface (GUI). Identical to a personal computer, web servers also feature an Operating System which serves as a host for any software installed on them, which includes 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 to the physical server host OS.
Multiple OS in VPS Hosting
In case you choose to acquire one of our virtual private server plans, you'll be able to select one of the three Linux distributions that we offer for the Operating System of the servers - CentOS, Ubuntu and Debian. These are among the most popular and most dependable server OSs on the market and we offer them in order to give you a choice for the software environment of your machine in case that you would like to install some application with specific requirements regarding the packages that must be present on the web hosting server. We also offer three internet hosting Control Panels and which one of them you can use will depend on the OS that you have selected. We leave the option to change the server Operating System open, so when you want to use an application that requires an OS different from the one you already have, we can always reinstall the VPS. We can also keep the OS up-to-date on a weekly basis by installing all the security updates that may be released.
Multiple OS in Dedicated Web Hosting
In case you decide to purchase one of our dedicated servers, you will find three Operating Systems on the registration page because we want to give you a larger choice for the system environment on the server as different apps could have certain requirements. CentOS, Ubuntu and Debian include different modules developed by their vast support communities, so you can select any of these OSs and enjoy a stable and safe hosting service. Depending on your selection, you will also have different Control Panels to choose from. Of course, we can always change the Operating System in case the one you've selected initially does not meet the requirements of the software that you want to run. We can also update your OS on a regular basis to keep it as risk-free as possible with our Managed Services upgrade package.
