Every notebook or desktop or server is run by an Operating System - the low-level program that communicates with the hardware, including peripherals such as a mouse and a printer, as well as any apps that are present on your system. Any program input through a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the Operating System. On a server, each application runs within the parameters defined by the OS as well - priority, physical memory, processing time, and so on. This goes for both standard site scripts and server-side software such as a media server. If a virtual server is created on a physical one, there can be two different Operating Systems, named guest OS and host OS, so that you will be able to set up a different software environment on the very same machine.
Multiple OS in VPS Servers
If you pick one of our VPS server solutions, you'll have 3 different Operating Systems to select from - CentOS, Debian and Ubuntu. They're all Linux releases and we offer them instead of offering just a single OS, because the applications that you might choose to run on the server could have specific requirements for the software environment. Each of the three has certain advantages regarding the available packages that you can afterwards install, but what's common between them is the fact that they're really secure and reliable and have huge communities which support them. The hosting Control Panel options for the VPS accounts depend on your OS choice, in order to give you more flexibility. If 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 matter of minutes. We also offer you the option to maintain the Operating System on your server up-to-date weekly.
Multiple OS in Dedicated Servers
In case you decide to obtain one of our dedicated servers, you'll find three Operating Systems on the order page since we want to give you a wider choice for the system environment on your machine as different applications may have certain requirements. CentOS, Ubuntu and Debian come with different modules developed by their huge support communities, so you can select each of these OSs and benefit from a stable and safe hosting service. Depending on your choice, you will also have different Control Panels to choose from. Needless to say, we can always replace the Operating System if the one you've selected initially does not meet the requirements of the software that you would like to run. We can also upgrade the OS routinely in order to keep it as secure as possible with our Managed Services upgrade package.
