Each and every desktop or notebook or server is run by an Operating System - the low-level program that communicates with the computer hardware, including peripheral devices such as a mouse and a printer, along with any applications 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 OS. On a web server, every single application runs within the parameters set by the OS as well - priority, physical memory, processing time, etc. This goes for both standard website scripts and server-side software such as a media server. If 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 same machine.
Multiple OS in VPS Servers
In case you pick one of our VPS server
plans, you will have 3 different Operating Systems to choose from - CentOS, Debian and Ubuntu. They're all Linux distributions and we offer them rather than offering just a single OS, since the applications that you may wish to run on the server may have specific requirements for the software environment. Each one of these three has certain pros in terms of the available plans that you may later install, but what is common between them is that they're really stable and reliable and have huge communities which support them. The hosting Control Panel alternatives for the VPS accounts depend on your OS 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 technical support team can easily reinstall the VPS with the new one in a matter 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
plans that we offer come with as many as three different Operating Systems to choose from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they are also regarded as the most reliable and risk-free OSs. We provide three different ones because each of them is backed by a different community. The packages which you could add on your web server are different and this could matter in case you want to install some piece of software with particular requirements regarding the hosting environment. In this light, the hosting Control Panel which you can select for the dedicated server is also determined by the Operating System that you'll choose. You may choose any of the three Operating Systems during the order procedure, but if necessary, we can always set up the server anew with another one upon your request. As an additional service that you can add to the package whenever you want, we can update your OS regularly so as to keep it as secure as possible.
