Every single notebook or desktop or web server is run by an Operating System - the low-level program that interacts with the hardware, including peripheral devices such as a mouse and a printer, as well as any applications that are present on the 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 OS. On a server, each and every application runs within the parameters established by the OS as well - priority, physical memory, processing time, etcetera. This goes for both standard site scripts and server-side software like a media server. If a virtual server is created on a physical one, there can be two different Operating Systems, referred to as guest OS and host OS, which means that you'll be able to set up a different software environment on a single machine.
Multiple OS in VPS Servers
If you choose to buy one of our VPS server packages, you shall be able to pick one of the three Linux releases that we provide for the OS of the servers - CentOS, Ubuntu and Debian. They're among the most popular and most dependable server OSs on the market and we offer them in order to give you a choice for the software environment of your machine if you want to install some app with particular requirements in terms of the packages that should be present on the web hosting server. We also offer three hosting Control Panels and which one of them you can use depends on the OS that you've selected. We leave the possibility to replace the server Operating System open, so when you want to use an application that requires an OS different from the one you have, we can always re-install the VPS. We can also keep the OS up-to-date weekly by installing any security updates which may be available.
Multiple OS in Dedicated Servers
The dedicated servers we offer can be installed with three different Operating Systems since we want to offer you more flexible plans which will allow you to 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 among the most dependable and safe ones, not mentioning that they don't have any kind of license charges. All three have a large number of developers that have created numerous software packages that you can install and use on your hosting server. We also offer three internet hosting Control Panels and which one you can use depends on the Operating System that you choose when you register. In case you need another OS later, it won't be a problem because we can always reinstall your server. With our Managed Services package we can also keep your OS secure by upgrading it every week with all patches that are released for it.
