Each and every personal computer or web server is run by an Operating System - the low-level software which communicates with the computer hardware, including peripheral devices such as a mouse and a printer, and any apps that are 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 web server, every single application runs within the parameters established 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 generated on a physical one, there can be two independent Operating Systems, named guest OS and host OS, so you can set up a different software environment on a single machine.
Multiple OS in VPS Servers
If you decide to acquire one of our VPS server
plans, you'll be able to select one of the three Linux distributions which we supply for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most popular and most dependable server OSs available and we offer them in order to give you a choice for the software environment of your machine in case that you would like to install some application with particular requirements with regards to the packages that must 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 have selected. We leave the possibility to replace the server Operating System open, so if you want to use software that requires an OS different from the one that's already present, we can always re-install the VPS. In addition, we can keep the OS up-to-date on a weekly basis by installing all of the security updates which may be released.
Multiple OS in Dedicated Servers
The dedicated server
solutions that we offer come with three different Operating Systems to choose from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they’re also regarded as the most stable and secure OSs. We offer three different ones for the reason that each one of them is backed by a different community. The packages that you could add on your hosting server are different and this could matter if you want to install some piece of software with particular requirements about the hosting environment. In this light, the internet hosting Control Panel which you can select for the dedicated server also depends on the Operating System that you will pick. You can pick any of the three Operating Systems during the order process, yet if needed, we can always install the server anew with an alternative one upon your request. As an optional service that you may add to the package at any time, we can update the OS on a regular basis in order to keep it as secure as possible.
