Every single PC or web server is run by an Operating System - the low-level software which interacts with the hardware, including peripheral devices such as a mouse and a printer, along with any apps that are installed 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 Operating System. On a web server, each application runs within the parameters defined by the OS as well - priority, physical memory, processing time, and so on. This goes for both standard website scripts and server-side software like a media server. If a virtual server is set up on a physical one, there can be two different Operating Systems, named guest OS and host OS, so that you'll be able to set up a different software environment on the very same machine.
Multiple OS in VPS Hosting
If you decide to purchase one of our virtual private server plans, you will be able to pick one of the three Linux releases which we offer for the Operating System of the servers - CentOS, Ubuntu and Debian. They are among the most popular and most reliable server OSs on the market and we offer them so that you have a choice for the software environment of your machine in case that you want to install some app with specific requirements in terms of the packages that should be present on the server. We also offer three web hosting Control Panels and which one of them you may use will depend on the OS that you've chosen. We leave the option to replace the server Operating System open, so if you want to use an app that requires an OS different from the one you already have, we can always reinstall the VPS. We can also keep the OS up-to-date on a weekly basis by installing any security updates that may be available.
Multiple OS in Dedicated Web Hosting
The dedicated servers we offer can be set up with as many as 3 different Operating Systems because we want to offer you more flexible packages which will permit you to install and run any kind of web software irrespective of its system requirements. The choices are CentOS, Debian and Ubuntu and these three OSs are some of the most reliable and risk-free ones, not mentioning that they don't have any kind of license costs. All three have numerous developers that have created countless 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 depends on the Operating System that you select when you sign up. If you need a new OS later, it won't be a problem since 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.
