An Operating System is the software that interacts with the hardware of a computer and functions as the intermediary between the installed applications and the hardware, which includes peripheral devices such as a printer, a mouse or a keyboard. When you run an application, it transmits requests to the OS using an API (Application Program Interface) and the communication is done through a command line or a Graphical User Interface (GUI). Identical to a personal computer, web hosting servers also feature an Operating System which serves as a host for any software installed on them, including 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 could install a guest OS on it and have a different system environment in contrast with the physical server host Operating System.

Multiple OS in VPS

If you pick one of our virtual private server plans, you'll have as many as 3 different Operating Systems to pick from - CentOS, Debian and Ubuntu. They're all Linux releases and we offer them instead of offering just a single OS, as the apps that you might choose to run on the server may have specific requirements regarding the software environment. Each one of the three has some pros regarding the available packages that you may later on install, but what is common between them is the fact that they're really secure and reliable and have huge communities that support them. The hosting Control Panel options for the VPS accounts depend on your OS choice, in order to give you more flexibility. In case you order the virtual server with one OS and you need a different one later, our tech support team can easily reinstall the VPS with the new one in a matter 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 Hosting

If you decide to acquire one of our dedicated servers, you will find three Operating Systems on the registration page because we want to give you a broader choice for the system environment on your machine as different apps can have certain requirements. CentOS, Ubuntu and Debian contain different modules developed by their vast support communities, so you can select any of these OSs and benefit from a reliable and risk-free Internet hosting service. Depending on your choice, 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 have selected in the beginning doesn't meet the requirements of the software which you'd like to run. We can also upgrade your OS routinely in order to keep it as risk-free as possible through our Managed Services upgrade package.
