An Operating System is the software that interacts with the hardware of a computer and is 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 transmits 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 feature an Operating System which functions as a host for all the software installed on them, which includes script apps or server-side software such as a flash server, a VOIP server, and many others. 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 compared to the physical server host Operating System.

Multiple OS in VPS Servers

If you decide to buy one of our VPS server packages, you will be able to select one of the three Linux distributions which we supply for the Operating System of the servers - CentOS, Ubuntu and Debian. They are among the most well-known and most dependable server OSs available 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 need to install some app with precise requirements regarding the packages that should be present on the server. We also offer three hosting Control Panels and which one of them you can use depends on the OS that you've chosen. 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 all of the security updates which may be available.

Multiple OS in Dedicated Servers

If you decide to obtain one of our dedicated servers, you'll find three Operating Systems on the order page because we want to give you a wider choice for the system environment on your server as different applications can have certain requirements. CentOS, Ubuntu and Debian contain different modules developed by their vast support communities, so you can select any of these OSs and take advantage of a reliable and secure hosting service. Depending on your selection, you will also have different Control Panels to choose from. Needless to say, we can always change the Operating System in case the one you have selected in the beginning does not meet the requirements of the software which you intend to run. We can also upgrade your OS regularly in order to keep it as risk-free as possible with our Managed Services upgrade package.
