Every single PC or server is run by an Operating System - the low-level software that interacts with the hardware equipment, including peripherals such as a mouse and a printer, and any applications that are currently installed on your system. Any program input using a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the Operating System. On a server, each application runs within the parameters specified by the OS as well - priority, physical memory, processing time, etc. This is valid for both standard website scripts and server-side software like a media server. In case a virtual server is generated on a physical one, there can be two independent Operating Systems, named guest OS and host OS, so you can set up a different software environment on the very same machine.
Multiple OS in VPS Servers
We offer as many as 3 different Linux releases for the Operating System of our VPS servers - Debian, CentOS and Ubuntu. These are some of the safest and the most reliable OSs on the market and we supply all 3 rather than just 1 because we realize that you might want to install some software with specific requirements regarding the Operating System it shall run on. The latter is because each of the three Operating Systems has a large support community behind it and there're different software packages you may install on the web server. Your OS selection will also determine what hosting Control Panel can be set up on the VPS if you want to use one and for this reason we offer several Control Panels too. Should you decide that you need to have some other OS, our technical support can quickly wipe the present one and install the one that you want. We also offer an optional service to have the OS on your VPS updated weekly.
Multiple OS in Dedicated Servers
If you decide to acquire one of our dedicated servers, you'll find three Operating Systems on the order page since we want to give you a broader choice regarding the system environment on the server as different apps may have specific requirements. CentOS, Ubuntu and Debian feature different modules developed by their huge support communities, so you can select any of these OSs and enjoy a stable and safe hosting service. Depending on your selection, you will also have different Control Panels to choose from. Of course, we can always replace the Operating System in case the one you've selected at first does not meet the requirements of the software which you'd like to run. We can also upgrade the OS on a regular basis in order to keep it as risk-free as possible using our Managed Services upgrade package.
