An Operating System is the software which communicates with the hardware of a computer and functions as the intermediary between the installed applications and the hardware, including peripheral devices such as a printer, a computer mouse or a keyboard. When you run software, it transmits requests to the OS using an API (Application Program Interface) and the communication is done via a command line or a Graphical User Interface (GUI). Identical to a personal computer, web servers also use an Operating System that acts as a host for the software installed on them, including script apps or server-side software such as a flash server, a VOIP server, etc. A virtual machine can be created 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 provide as many as three different Linux distributions for the Operating System of our VPS servers - Debian, CentOS and Ubuntu. These are among the most stable and reliable OSs you can find and we offer all three instead of only one because we realize that you might want to set up some software with specific requirements with regards to the Operating System it'll run on. The latter is due to the fact that each of the three Operating Systems has a huge support community behind it and there are different software packages you may install on the hosting server. Your OS choice will also determine exactly what hosting Control Panel can be installed on the VPS in case you want to use one and because of this we offer multiple Control Panels too. In the event you decide that you need to have another OS, our technical support can quickly wipe the present one and install the one that you would like. In addition, we offer an optional service to maintain the OS on your VPS updated weekly.
