Every single personal computer or server is run by an Operating System - the low-level software that communicates with the computer hardware, including peripherals such as a mouse and a printer, and any apps that are present on the 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 app runs within the parameters set by the OS as well - priority, physical memory, processing time, and so on. This goes 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 different Operating Systems, called guest OS and host OS, so that you'll be able to set up a different software environment on a single machine.
Multiple OS in VPS Hosting
If you choose one of our virtual private server solutions, you will have three different Operating Systems to select from - CentOS, Debian and Ubuntu. They are all Linux releases and we offer them instead of offering just one OS, because the applications that you may want to run on the server may have specific requirements about the software environment. Each one of these three has certain advantages regarding the available packages that you could later install, but what's common between them is that they are very stable and reliable and have huge communities which support them. The hosting Control Panel options for the VPS accounts depend on your Operating System choice, in order to provide you with 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 couple of minutes. We also offer you the option to maintain the Operating System on your server up-to-date on a weekly basis.
Multiple OS in Dedicated Web Hosting
In case you decide to acquire one of our dedicated servers, you will find three Operating Systems on the order page since we want to give you a broader choice with regard to the system environment on the server as different apps may have certain requirements. CentOS, Ubuntu and Debian come with different modules developed by their vast support communities, so you can select each of these OSs and benefit from a reliable and safe web hosting service. Based on your choice, you will also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you've selected at first does not meet the requirements of the software which you would like to run. We can also update the OS regularly in order to keep it as secure as possible using our Managed Services upgrade package.
