An Operating System is the low-level software which manages a computer. It controls how the hardware behaves, the communication with peripherals for instance a monitor, a printer or a keyboard, the allocation of memory between various applications, and the prioritization of apps if several run concurrently. Each program that is installed on a PC works by sending requests to the OS for different services by using an application program interface (API). The interaction with the OS is possible using a Graphical User Interface (GUI) or a command line. In the hosting world, the Operating System is what controls a web hosting server along with all of the software installed on it, which includes not only website scripts, but, in addition any other application such as a VOIP or a game server. When there are virtual machines created, they use a guest OS which runs on the server host OS.
Multiple OS in VPS Web Hosting
In case you choose to buy one of our virtual private server packages, you will be able to opt for one of the three Linux distributions that we supply for the OS of the servers - CentOS, Ubuntu and Debian. They're among the most preferred and most dependable server OSs out there and we offer them so that you have a choice for the software environment of your machine in case that you need to install some app with particular requirements in terms of the packages that must be present on the hosting server. We also offer three hosting Control Panels and which one of them you may use will depend on the OS that you have selected. We leave the possibility to replace the server Operating System open, so when you want to use an app that requires an OS different from the one that's already present, we can always reinstall the VPS. In addition, we can keep the OS up-to-date weekly by installing all of the security updates that may be available.
Multiple OS in Dedicated Servers Hosting
In case you decide to acquire one of our dedicated servers, you'll find three Operating Systems on the registration page because we want to give you a wider choice regarding the system environment on the server as different applications may have certain requirements. CentOS, Ubuntu and Debian come with different modules developed by their large support communities, so you can select each of these OSs and benefit from a stable and safe Internet hosting service. Based on your choice, 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 initially doesn't meet the requirements of the software which you would like to run. We can also upgrade the OS regularly in order to keep it as secure as possible using our Managed Services upgrade package.
