Every single PC or server is run by an Operating System - the low-level program that interacts with the hardware equipment, including peripheral devices such as a mouse and a printer, along with any apps 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, every single app runs within the parameters established by the OS as well - priority, physical memory, processing time, etc. This goes for both standard site scripts and server-side software such as a media server. If a virtual server is set up on a physical one, there can be two separate Operating Systems, referred to as guest OS and host OS, which means that you can set up a different software environment on a single machine.
Multiple OS in VPS Servers
In case you decide to purchase one of our VPS server packages, you'll be able to choose one of the three Linux distributions that we offer for the Operating System of the servers - CentOS, Ubuntu and Debian. They are among the most preferred and most reliable server OSs available on the market and we offer them so that you have a choice for the software environment of your machine in case that you need to install some application with precise requirements regarding the packages that should be present on the web hosting server. We also offer three web hosting Control Panels and which one of them you can use depends on the OS that you've chosen. We leave the possibility to replace the server Operating System open, so if you want to use an application that requires an OS different from the one you have, we can always reinstall the VPS. We can also keep the OS up-to-date on a weekly basis by installing all the security updates which may be released.
Multiple OS in Dedicated Servers
The dedicated servers we offer can be installed with as many as three different Operating Systems since we want to offer you more flexible solutions that will let you install and run any type of web software regardless of its system requirements. The options are CentOS, Debian and Ubuntu and these 3 OSs are some of the most dependable and secure ones, not mentioning that they don't have any kind of license charges. All three have a large number of developers who have created a large number of software packages that you may 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. If you need a different OS subsequently, it won't be a problem as we can always reinstall your server. With our Managed Services package we could also keep your OS secure by updating it every week with all patches that are available for it.
