Every personal computer or web server is run by an Operating System - the low-level program that interacts with the hardware, including peripherals such as a mouse or a printer, as well as any apps that are present on the 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 web server, each app runs within the parameters defined by the OS as well - priority, physical memory, processing time, etcetera. This is valid for both standard site scripts and server-side software such as a media server. In case a virtual server is set up on a physical one, there can be two separate Operating Systems, referred to as guest OS and host OS, so that you will be able to set up a different software environment on a single machine.
Multiple OS in Dedicated Servers
The dedicated servers
we offer come with as many as 3 different Operating Systems since we want to offer you more versatile packages that will enable you to install and run any web software whatever its system requirements. Your choices are CentOS, Debian and Ubuntu and these three OSs are among the most stable and safe ones, not mentioning that they don't have any kind of license fees. All three have numerous developers that have created a large number of software packages that you'll be able to install and use on your web server. We also offer three web hosting Control Panels and which one you can use is determined by the Operating System that you select when you sign up. In case you need a new OS later, it won't be a problem as we can always reinstall your server. With our Managed Services package we could also keep your OS secure by updating it every week with any patches that are released for it.
