An Operating System is the software that communicates with the hardware of a computer system and serves as the intermediary between all the applications and the hardware, which includes peripherals such as a printer, a computer mouse or a keyboard. When you run an application, it sends requests to the OS through an API (Application Program Interface) and the interaction is done via a command line or a Graphical User Interface (GUI). Just like a personal computer, web servers also use an Operating System that functions as a host for the software installed on them, which includes script apps or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be generated on a physical one, so you'll be able to 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 choose one of our VPS server packages, you will have 3 different Operating Systems to select from - CentOS, Debian and Ubuntu. They are all Linux releases and we offer them instead of offering just a single OS, because the applications that you might want to run on the server could have specific requirements about the software environment. Each one of these three has some advantages with regard to the available packages that you can afterwards install, but what's common between them is the fact that they are really secure and reliable and have huge communities which support them. The internet hosting Control Panel choices for the VPS accounts depend on your OS choice, so as to give you more flexibility. In case you order the virtual server with one OS and you need another one later, our technical support team can easily reinstall the VPS with the new one in a couple of minutes. We also offer you the option to keep the Operating System on your server up-to-date on a weekly basis.
Multiple OS in Dedicated Servers
The dedicated servers we offer can be installed with as many as three different Operating Systems because we want to give you more flexible plans that will allow you to install and run any type of web software irrespective of its system requirements. The choices are CentOS, Debian and Ubuntu and these three OSs are among the most stable and safe ones, not mentioning that they don't have any license charges. All three have numerous developers who have created countless software packages that you'll be able to install and use on your web server. We also offer three hosting Control Panels and which one you can use is determined by the Operating System that you select when you sign up. If you need a different OS later on, it won't be a problem since we can always reinstall your machine. With our Managed Services package we could also keep your OS secure by updating it on a weekly basis with any patches that are available for it.
