An Operating System is the software that communicates with the hardware of a computer and works as the intermediary between apps and the hardware, which includes peripheral devices such as a printer, a mouse or a keyboard. When you run an app, it sends requests to the OS through an API (Application Program Interface) and the contact is done through a command line or a Graphical User Interface (GUI). Just like a personal computer, web hosting servers also have an Operating System which functions as a host for the software installed on them, including script applications or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be generated on a physical one, so it is possible to install a guest OS on it and have a different system environment in contrast with the physical server host OS.
Multiple OS in VPS Servers
In case you decide to acquire one of our VPS server plans, you will be able to pick one of the three Linux distributions that we provide for the OS of the servers - CentOS, Ubuntu and Debian. They are among the most well-known and most dependable server OSs available on the market and we offer them in order to give you a choice for the software environment of your machine in case that you need to install some app with particular requirements in terms of the packages that have to be present on the server. We also offer three web hosting Control Panels and which one of them you may use depends on the OS that you have chosen. We leave the possibility to replace the server Operating System open, so if you want to use an application that requires an OS different from the one you have, we can always re-install the VPS. We can also keep the OS up-to-date weekly by installing all of the security updates which may be released.
Multiple OS in Dedicated Servers
We offer three Operating Systems with our dedicated server packages - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they are completely free and they will not increase the low price of your new web server, but also because they are really stable and secure. Each one of them is supported by a large community of developers, so you'll be able to choose from a large number software packages that you may install on your server in case the application that you would like to work with has specific requirements. The Operating System will also determine what hosting Control Panel you can use as the Control Panels that we offer are compatible with specific OSs only and since we would like to provide you with as much flexibility as possible, we offer a couple of OSs and multiple Control Panels. If you get a server with a given OS, we could change it upon request in case it turns out that you need alternative one. We will also keep the OS updated weekly as a part of our useful Managed Services upgrade.
