An Operating System is the software that interacts with the hardware of a PC and works as the intermediary between the installed applications and the hardware, which includes peripheral devices such as a printer, a mouse or a keyboard. When you run software, it transfers requests to the OS through an API (Application Program Interface) and the communication is done via a command line or a Graphical User Interface (GUI). Similar to a personal computer, web servers also have an Operating System that acts as a host for any software installed on them, which includes script apps or server-side software such as a flash server, a VOIP server, etc. A virtual machine can be set up 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 Operating System.
Multiple OS in VPS Servers
In case you choose to acquire one of our VPS server
plans, you'll be able to pick one of the three Linux distributions that we offer for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most widespread and most stable server OSs out there and we offer them in order to give you a choice for the software environment of your machine if you want to install some application with precise requirements regarding the packages that should be present on the server. We also offer three hosting Control Panels and which one of them you can use will depend on the OS that you've selected. We leave the possibility to change the server Operating System open, so if you want to use an app that requires an OS different from the one that's already present, we can always re-install the VPS. We can also keep the OS up-to-date on a weekly basis by installing all the security updates which may be available.
Multiple OS in Dedicated Servers
The dedicated server
solutions that we offer come with as many as three different Operating Systems to pick from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license fees, but they’re also considered to be among the most dependable and safe OSs. We supply three different ones because each one of them is backed by a separate community. The packages that you can add on your hosting server are different and this could matter if you need to install some piece of software with specific requirements about the hosting environment. In this light, the hosting Control Panel which you can select for the dedicated server is also determined by the Operating System that you'll pick. You can choose any of the three Operating Systems during the order procedure, but if needed, we can always set up the server once again with an alternative one upon your request. As an additional service that you can add to the plan at any moment, we can update the OS on a regular basis to keep it as risk-free as possible.
