Each personal computer or server is run by an Operating System - the low-level program which interacts with the computer hardware, including peripheral devices such as a mouse or a printer, together with any applications that are present on your system. Any program input using a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the OS. On a server, any application runs within the parameters defined by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard website scripts and server-side software such as a media server. When a virtual server is created on a physical one, there can be two independent Operating Systems, called guest OS and host OS, so you will be able to set up a different software environment on a single machine.
Multiple OS in VPS
If you choose one of our virtual private server
plans, you'll have three 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 apps that you may wish to run on the server could have specific requirements regarding the software environment. Each one of these three has some advantages with regard to the available plans that you may later install, but what is common between them is the fact that they are really stable and reliable and have large communities that support them. The hosting Control Panel options 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 another one later, our tech support team can easily reinstall the VPS with the new one in just a few 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 acquire one of our dedicated servers
, you shall find three Operating Systems on the registration page because we want to give you a larger choice for the system environment on the machine as different applications may have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their huge support communities, so you can select any of these OSs and take advantage of a reliable and risk-free Internet 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 doesn't meet the requirements of the software which you intend to run. We can also upgrade your OS routinely to keep it as secure as possible with our Managed Services upgrade package.
