Each and every PC or server is run by an Operating System - the low-level software that interacts with the hardware, including peripheral devices such as a mouse or a printer, and any apps that are installed 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 Operating System. On a web server, each application runs within the parameters established by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard site scripts and server-side software like a media server. In case a virtual server is created on a physical one, there can be two separate Operating Systems, referred to as guest OS and host OS, so that you'll be able to set up a different software environment on a single machine.

Multiple OS in VPS Servers

If you pick one of our VPS server plans, you will have three different Operating Systems to pick from - CentOS, Debian and Ubuntu. They're all Linux releases and we offer them instead of offering just a single OS, because the apps that you may want to run on the server could have specific requirements about the software environment. Each one of these three has some pros regarding the available plans that you could eventually install, but what's common between them is that they are really stable and reliable and have huge communities which support them. The web hosting Control Panel choices for the VPS accounts depend on your Operating System choice, in order to give you 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 matter of minutes. We also offer 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 plans that we offer come with as many as three different Operating Systems to select from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they’re also known as the most reliable and safe OSs. We supply three different ones because each of them is supported by a separate community. The packages which you could add on your web server are different and this may matter in case you want to install some piece of software with particular requirements for the hosting environment. In this light, the web hosting Control Panel that you can select for the dedicated server is also determined by the Operating System that you'll choose. You can pick any of the three Operating Systems during the order process, but if necessary, we can always install the server once again with a different one upon your request. As an optional service that you could add to the package whenever you want, we can update the OS regularly to keep it as secure as possible.
