Every desktop or notebook or web server is run by an Operating System - the low-level software which interacts with the computer hardware, including peripheral devices such as a mouse and a printer, and any apps that are present on the system. Any program input through a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the OS. On a server, every single app runs within the parameters set by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard Internet site scripts and server-side software like a media server. In case a virtual server is set up on a physical one, there can be two separate Operating Systems, named guest OS and host OS, so that you will be able to set up a different software environment on the same machine.
Multiple OS in VPS
We provide three different Linux releases for the Operating System of our virtual private servers - Debian, CentOS and Ubuntu. These are among the safest and the most reliable OSs on the market and we offer all three of them instead of just 1 because we realize that you may want to install some software that has specific requirements regarding 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're different software packages you could install on the hosting server. Your OS selection will also determine what hosting Control Panel can be set up on the VPS in case you want to use one and because of this we offer multiple Control Panels too. If you ever decide that you need to have a different OS, our technical support can quickly wipe the current one and install the one that you want. In addition, we offer an optional service to keep the OS on your VPS updated weekly.
Multiple OS in Dedicated Hosting
The dedicated servers that we offer can be installed with as many as 3 different Operating Systems since we want to give you more flexible plans that will let you install and run any type of web software irrespective of its system requirements. Your choices are CentOS, Debian and Ubuntu and these 3 OSs are some of the most reliable and secure ones, not mentioning that they do not have any kind of license costs. All three have numerous developers that have created a huge number of software packages that you may install and use on your hosting server. We also offer three web hosting Control Panels and which one you can use is determined by the Operating System that you select when you register. In case you need some other OS afterwards, it will not be a problem as we can always reinstall your machine. With our Managed Services package we could also keep your OS secure by upgrading it every week with any patches that are available for it.
