An Operating System is the software which interacts with the hardware of a computer system and serves as the intermediary between all the applications and the hardware, which includes peripheral devices such as a printer, a mouse or a keyboard. When you run an app, it transfers 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 hosting servers also have an Operating System that acts as a host for all of 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 generated on a physical one, so you'll be able to install a guest OS on it and have a different system environment in contrast to the physical server host Operating System.
Multiple OS in VPS Servers
We offer you as many as three different Linux releases for the Operating System of our VPS servers - Debian, CentOS and Ubuntu. These are some of the most stable and reliable OSs out there and we provide all 3 rather than only 1 because we realize that you may want to set up some software with specific requirements for the Operating System it will run on. The latter is because each of the three Operating Systems has a huge support community behind it and there are various software packages you could install on the server. Your OS choice will also determine exactly what hosting Control Panel can be installed on the VPS in case you would like to use one and that's why we offer several Control Panels as well. If you ever decide that you need some other OS, our tech support can quickly wipe the existing one and set up the one that you would like. We also offer an optional service to have the OS on your VPS updated weekly.
Multiple OS in Dedicated Servers
The dedicated servers we offer can be installed with as many as 3 different Operating Systems because we want to offer you more flexible solutions that will enable you to install and run any kind of web software irrespective of its system requirements. Your options are CentOS, Debian and Ubuntu and these 3 OSs are among the most stable and risk-free ones, not mentioning that they don't have any license fees. All three have thousands of developers that have created a large number of software packages that you can install and use on your server. We also offer three web hosting Control Panels and which one you can use depends on the Operating System that you select when you sign up. In case you need a new OS afterwards, it won't be a problem since we can always reinstall your server. With our Managed Services package we can also keep your OS secure by updating it on a weekly basis with all patches that are available for it.
