Every single personal computer or server is run by an Operating System - the low-level program that communicates with the computer hardware, including peripheral devices such as a mouse or 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 OS. On a server, each app runs within the parameters established by the OS as well - priority, physical memory, processing time, etc. This goes for both standard website scripts and server-side software like a media server. When a virtual server is created on a physical one, there can be two independent Operating Systems, named guest OS and host OS, which means that you can set up a different software environment on the same machine.
Multiple OS in VPS Servers
In case you choose to go for one of our VPS server packages, you shall be able to choose one of the three Linux releases which we supply for the Operating System of the servers - CentOS, Ubuntu and Debian. These are among the most well-known and most dependable server OSs available on the market and we offer them so that you have a choice for the software environment of your machine if you need to install some app with specific requirements with regards to the packages that must be present on the server. We also offer three internet hosting Control Panels and which one of them you can use depends on the OS that you have selected. We leave the chance to replace the server Operating System open, so when you want to use an app that requires an OS different from the one you already have, we can always reinstall the VPS. We can also keep the OS up-to-date weekly by installing any security updates which may be released.
Multiple OS in Dedicated Servers
In case you decide to acquire one of our dedicated servers, you shall find three Operating Systems on the registration page since we want to give you a broader choice regarding the system environment on the server as different applications could have specific requirements. CentOS, Ubuntu and Debian contain different modules developed by their large support communities, so you can select each of these OSs and benefit from a reliable and risk-free hosting service. Depending on your decision, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System if the one you've selected in the beginning doesn't meet the requirements of the software which you intend to run. We can also upgrade your OS on a regular basis in order to keep it as risk-free as possible with our Managed Services upgrade package.
