An Operating System is the software that communicates with the hardware of a PC and is the intermediary between applications and the hardware, which includes peripherals such as a printer, a mouse or a keyboard. When you run an application, it sends requests to the OS through an API (Application Program Interface) and the communication is done through a command line or a Graphical User Interface (GUI). Just like a personal computer, web servers also feature an Operating System that acts as a host for any software installed on them, including script apps 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 can install a guest OS on it and have a different system environment in contrast to the physical server host OS.
Multiple OS in VPS Servers
In case you choose to buy one of our VPS server plans, you shall be able to choose one of the three Linux distributions which we supply for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most popular and most stable server OSs on the market and we offer them so that you have a choice for the software environment of your machine in case that you need to install some app with particular requirements regarding the packages that need to be present on the web hosting server. We also offer three internet hosting Control Panels and which one of them you'll be able to use will depend on the OS that you have picked. We leave the chance to change the server Operating System open, so when you want to use an application that requires an OS different from the one you have, we can always reinstall the VPS. We can also keep the OS up-to-date weekly by installing all the security updates which 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 absolutely free so they will not increase the price of your new server, but also because they are extremely stable and secure. Each one of them is backed up by a large community of developers, so you will be able to choose from many hundreds of software packages that you may install on your server in case the app that you intend to employ has specific requirements. The Operating System will also determine what internet hosting Control Panel you can use as the Control Panels that we offer run on particular OSs only and since we want to provide you with as much freedom as possible, we offer several OSs and multiple Control Panels. In case you choose a server with a given OS, we will change it upon request if it turns out that you'll need alternative one. We can also keep the OS updated on a weekly basis as a part of the additional Managed Services upgrade.
