An Operating System is the basic software that controls a PC. It takes care of the way the hardware behaves, the communication with peripheral devices for instance a monitor, a printer or a keyboard, the allocation of memory between applications, along with the prioritization of apps if several run simultaneously. Each program that's installed on a desktop or a notebook functions by sending requests to the OS for various services by using an application program interface (API). The interaction with the OS can be achieved via a Graphical User Interface (GUI) or a command line. In the web hosting field, the OS is what commands a server and any software installed on it, which includes not only website scripts, but, in addition every other application such as a VOIP or a game server. If there're virtual machines created, they work with a guest OS which runs on the server host OS.
Multiple OS in VPS Web Hosting
Our virtual private server plans feature three Linux distributions that you could pick from for the Operating System of your new hosting server - Debian, Ubuntu and CentOS. Apart from being cost-free, the OSs are extremely stable and safe and the key reason to offer all three of them is to ensure that you will be able to run every app that you'd like, because different pieces of software may have different requirements for the environment they can be used on. Each of the three OSs is backed by a huge community of web developers who have generated thousands of software packages that you can set up and use on your VPS. Depending on the Operating System that you select, you will also be able to select between three different Control Panels to control your website hosting content. Needless to say, should you decide that you need another OS, we can always re-install the server with it. As an additional upgrade, we also provide weekly updates of the OS for max stability and security.
Multiple OS in Dedicated Servers Hosting
If you decide to buy one of our dedicated servers, you'll find three Operating Systems on the order page because we want to give you a broader choice for the system environment on the server as different apps could have specific requirements. CentOS, Ubuntu and Debian contain different modules developed by their large support communities, so you can select each of these OSs and take advantage of a reliable and safe web hosting service. Depending on your selection, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you've selected in the beginning does not meet the requirements of the software that you want to run. We can also update the OS regularly to keep it as risk-free as possible with our Managed Services upgrade package.
