An Operating System is the basic software that controls a computer system. It takes care of how your hardware functions, the communication with peripheral devices like a monitor, a printer or a keyboard, the allocation of memory between applications, along with the prioritization of apps when several run at once. Any program that's installed on a desktop or a laptop works by sending requests to the OS for various services using an application program interface (API). The interaction with the OS can be achieved through a Graphical User Interface (GUI) or a command line. In the web hosting world, the Operating System is what commands a hosting server as well as any software installed on it, which includes not only website scripts, but, in addition every other application for instance a VOIP or a game server. If there are virtual machines created, they employ a guest OS that is run on the server host OS.
Multiple OS in VPS
If you choose to go for one of our virtual private server plans, you'll be able to opt for one of the three Linux releases which we provide for the OS of the servers - CentOS, Ubuntu and Debian. They're among the most widespread 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 would like to install some app with precise requirements regarding the packages that should be present on the server. We also offer three web hosting Control Panels and which one of them you'll be able to use will depend on the OS that you've chosen. 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 have, we can always reinstall the VPS. In addition, we can keep the OS up-to-date weekly by installing all the security updates which may be available.
Multiple OS in Dedicated Hosting
If you decide to obtain one of our dedicated servers, you shall find three Operating Systems on the registration page because we want to give you a wider choice with regard to the system environment on the machine as different applications may have specific requirements. CentOS, Ubuntu and Debian feature different modules developed by their huge support communities, so you can select any of these OSs and take advantage of a reliable and secure Internet hosting service. Based on your decision, 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 at first doesn't meet the requirements of the software which you'd like 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.
