An Operating System is the software that interacts with the hardware of a PC and is 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 software, it sends requests to the OS using 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 hosting servers also use an Operating System that acts as a host for all of the 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 you will be able to install a guest OS on it and have a different system environment in contrast with the physical server host OS.
Multiple OS in VPS
In case you select one of our virtual private server solutions, you will have as many as 3 different Operating Systems to select from - CentOS, Debian and Ubuntu. They're all Linux releases and we offer them rather than offering just a single OS, as the applications that you might want to run on the server may have specific requirements for the software environment. Each of these three has some pros in terms of the available plans that you could later install, but what is common between them is the fact that they're very stable and reliable and have huge communities which support them. The hosting Control Panel choices for the VPS accounts depend on your OS choice, so as to give you more flexibility. If you order the virtual server with one OS and you need a different one later, our technical support team can easily reinstall the VPS with the new one in a matter of minutes. We also offer the option to keep the Operating System on your server up-to-date on a weekly basis.
Multiple OS in Dedicated Hosting
In case you decide to purchase one of our dedicated servers, you will find three Operating Systems on the registration page as we want to give you a wider choice with regard to the system environment on your server as different apps may have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their vast support communities, so you can select any of these OSs and enjoy a reliable and secure hosting service. Depending on your choice, you'll also have different Control Panels to choose from. Of course, we can always replace the Operating System if the one you've selected in the beginning does not meet the requirements of the software which you would like to run. We can also upgrade your OS routinely in order to keep it as risk-free as possible using our Managed Services upgrade package.
