An Operating System is the software that communicates with the hardware of a PC and is the intermediary between applications and the hardware, including peripheral devices such as a printer, a computer mouse or a keyboard. When you run software, it sends requests to the OS using an API (Application Program Interface) and the contact is done via a command line or a Graphical User Interface (GUI). Identical to a personal computer, web hosting servers also have an Operating System which acts as a host for the software installed on them, including script applications or server-side software such as a flash server, a VOIP server, etcetera. A virtual machine can be created on a physical one, so you could 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 purchase one of our VPS server plans, you'll be able to pick one of the three Linux distributions that we offer for the Operating System of the servers - CentOS, Ubuntu and Debian. These are among the most popular and most dependable server OSs available and we offer them in order to give you a choice for the software environment of your machine in case that you intend to install some app with particular requirements in terms of the packages that have to be present on the web server. We also offer three internet hosting Control Panels and which one of them you could use will depend on the OS that you have selected. We leave the chance to change the server Operating System open, so when you want to use software that requires an OS different from the one that's already present, we can always re-install the VPS. In addition, we can keep the OS up-to-date weekly by installing all of the security updates that may be available.
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 freely available and they won't increase the cost of your new web server, but also because they are really stable and secure. Each of them is backed up by a vast community of web developers, so you'll be given the option to choose from a myriad of software packages that you could install on your server if the application that you want to employ has certain requirements. The Operating System will also determine what internet hosting Control Panel you can use since the Control Panels that we offer run on particular OSs only and because we would like to give you as much adaptability as possible, we offer several OSs and multiple Control Panels. If you choose a server with a certain OS, we could change it upon request in case it turns out that you'll need a different one. We will also keep your OS updated on a weekly basis as a part of the useful Managed Services upgrade.
