An Operating System is the software that interacts with the hardware of a computer system and is the intermediary between the installed applications and the hardware, including peripheral devices such as a printer, a mouse or a keyboard. When you run software, it sends 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, web hosting servers also use 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 created on a physical one, so it is possible to install a guest OS on it and have a different system environment in contrast to the physical server host OS.
Multiple OS in VPS Servers
If you decide to purchase one of our VPS server plans, you shall be able to pick 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 if you would like to install some application with precise requirements with regards to the packages that should be present on the server. We also offer three internet hosting Control Panels and which one of them you could use depends on the OS that you have picked. We leave the possibility to replace the server Operating System open, so if you want to use software that requires an OS different from the one that's already present, we can always re-install the VPS. We can also keep the OS up-to-date weekly by installing all the security updates that may be released.
Multiple OS in Dedicated Servers
In case you decide to purchase one of our dedicated servers, you shall 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 applications can have particular requirements. CentOS, Ubuntu and Debian include different modules developed by their vast support communities, so you can select each of these OSs and benefit from a stable and safe web hosting service. Based on your decision, you will also have different Control Panels to choose from. Needless to say, we can always change the Operating System if the one you have selected in the beginning doesn't meet the requirements of the software which you would like to run. We can also update your OS routinely to keep it as risk-free as possible using our Managed Services upgrade package.
