Each desktop or notebook or web server is run by an Operating System - the low-level software that communicates with the hardware, including peripherals such as a mouse and a printer, and any apps that are installed 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 server, each application runs within the parameters established by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard site scripts and server-side software such as a media server. When a virtual server is generated on a physical one, there can be two different Operating Systems, called guest OS and host OS, so that you can set up a different software environment on the same machine.

Multiple OS in Dedicated Web Hosting

We offer three Operating Systems with our dedicated server solutions - CentOS, Ubuntu and Debian. They are all different Linux distributions and we offer them not only because they're completely free so they will not increase the cost of your new server, but also because they are extremely secure and stable. Each one of them is supported by a vast community of developers, so you will be able to choose from many hundreds of software packages that you could install on your server if the application that you want to employ has specific requirements. The Operating System will also determine what hosting Control Panel you can use since the Control Panels that we offer are compatible with particular OSs only and because we want to provide you with as much freedom as possible, we offer multiple OSs and multiple Control Panels. In case you choose a server with a given Operating System, we will change it upon request in case it turns out that you need a different one. We will also keep your OS updated weekly as part of our additional Managed Services upgrade.
