An Operating System is the software which communicates with the hardware of a PC and works as the intermediary between apps and the hardware, which includes peripherals such as a printer, a mouse or a keyboard. When you run an application, it transfers 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 servers also use an Operating System which serves as a host for any software installed on them, which includes script applications or server-side software such as a flash server, a VOIP server, etcetera. A virtual machine can be set up on a physical one, so you'll be able to install a guest OS on it and have a different system environment in contrast with the physical server host Operating System.
Multiple OS in VPS Web Hosting
In case you choose to go for one of our virtual private server plans, you shall be able to pick one of the three Linux releases that we supply 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 need to install some application with specific requirements regarding the packages that have to be present on the server. We also offer three web hosting Control Panels and which one of them you could use depends on the OS that you have picked. We leave the chance to change the server Operating System open, so if you want to use an application that requires an OS different from the one you already have, we can always re-install the VPS. In addition, we can keep the OS up-to-date weekly by installing all the security updates which may be released.
Multiple OS in Dedicated Servers Hosting
We offer three Operating Systems with our dedicated server plans - CentOS, Ubuntu and Debian. They are all different Linux distributions and we offer them not only because they are freely available so they won't increase the low price of your new hosting server, but also because they are really secure and stable. Each one of them is supported by a huge community of web developers, so you will be able to choose from a large number software packages that you could install on your server if the app that you want to employ has certain requirements. The Operating System will also determine what web hosting Control Panel you can use since the Control Panels that we offer run on specific OSs only and because we want to give you as much freedom as possible, we offer multiple OSs and multiple Control Panels. If you get a server with a given Operating System, we can change it upon request in case it turns out that you will need a different one. We can also keep the OS updated weekly as part of the optional Managed Services upgrade.
