Every personal computer or web server is run by an Operating System - the low-level software which interacts with the hardware equipment, including peripheral devices such as a mouse or a printer, along with any applications 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 Operating System. On a server, each and every app runs within the parameters established by the OS as well - priority, physical memory, processing time, and so on. This goes for both standard site scripts and server-side software like a media server. When a virtual server is created on a physical one, there can be two independent Operating Systems, called guest OS and host OS, so that you can set up a different software environment on the very same machine.
Multiple OS in VPS Servers
If you select one of our VPS server plans, you will have three different Operating Systems to select from - CentOS, Debian and Ubuntu. They are all Linux distributions and we offer them instead of offering just a single OS, as the apps that you may wish to run on the server may have specific requirements regarding the software environment. Each of these three has some pros regarding the available plans that you can afterwards install, but what is common between them is that they're very stable and reliable and have large communities that support them. The web hosting Control Panel choices for the VPS accounts depend on your Operating System choice, in order to provide you with more flexibility. In case you order the virtual server with one OS and you need a different one later, our tech support team can easily reinstall the VPS with the new one in a couple of minutes. We also offer you the option to keep the Operating System on your server up-to-date on a weekly basis.
Multiple OS in Dedicated Servers
The dedicated server solutions that we offer come with as many as three different Operating Systems to choose from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license fees, but they’re also considered to be among the most stable and secure OSs. We provide three different ones as each of them is supported by a separate community. The packages which you could add on your server are different and this could matter in case you need to install some piece of software with specific requirements for the hosting environment. In this light, the internet hosting Control Panel that you can select for the dedicated server also depends on the Operating System that you'll select. You can select any of the three Operating Systems during the order procedure, however if needed, we can always install the server anew with a different one upon your request. As an additional service that you can add to the plan whenever you want, we can update your OS on a regular basis to keep it as secure as possible.
