Every desktop or notebook or web server is run by an Operating System - the low-level program that communicates with the hardware, including peripherals such as a mouse and a printer, as well as any apps that are currently 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 OS. On a server, any application runs within the parameters defined by the OS as well - priority, physical memory, processing time, etc. This is valid for both standard site scripts and server-side software such as a media server. In case a virtual server is set up on a physical one, there can be two independent Operating Systems, called guest OS and host OS, so that you'll be able to set up a different software environment on the same machine.
Multiple OS in VPS Servers
In case you decide to purchase one of our VPS server
plans, you will be able to opt for one of the three Linux distributions which we offer for the OS of the servers - CentOS, Ubuntu and Debian. They are among the most widespread and most reliable server OSs out there 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 specific requirements regarding the packages that must be present on the server. We also offer three hosting Control Panels and which one of them you may use will depend on the OS that you have picked. We leave the chance to change 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 weekly by installing any security updates which may be available.
Multiple OS in Dedicated Servers
The dedicated servers
that we offer can be installed with as many as three different Operating Systems since we want to give you more flexible packages that will let you install and run any web software regardless of its system requirements. Your options are CentOS, Debian and Ubuntu and these 3 OSs are among the most stable and safe ones, not mentioning that they do not have any kind of license charges. All three have thousands of developers that have created a huge number of 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 is determined by the Operating System that you select when you register. If you need another OS afterwards, 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 any patches which are released for it.
