An Operating System is the software which interacts with the hardware of a computer system and is the intermediary between apps and the hardware, which includes peripherals such as a printer, a mouse or a keyboard. When you run software, it transfers requests to the OS through an API (Application Program Interface) and the interaction is done via a command line or a Graphical User Interface (GUI). Similar to a personal computer, web servers also use an Operating System which serves as a host for the software installed on them, including script applications or server-side software such as a flash server, a VOIP server, etcetera. A virtual machine can be created on a physical one, so you can install a guest OS on it and have a different system environment in contrast with the physical server host OS.
Multiple OS in VPS Servers
If you select one of our VPS server
solutions, you'll have as many as three different Operating Systems to choose from - CentOS, Debian and Ubuntu. They're all Linux distributions and we offer them instead of offering just one OS, as the apps that you may want to run on the server may have specific requirements for the software environment. Each one of these three has certain advantages in terms of the available packages that you may later install, but what is common between them is the fact that they're 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, so as to give you more flexibility. If 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 the option to maintain the Operating System on your server up-to-date weekly.
Multiple OS in Dedicated Servers
In case you decide to purchase one of our dedicated servers
, you shall find three Operating Systems on the registration page as we want to give you a larger choice with regard to the system environment on your server as different apps could have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their vast support communities, so you can select any of these OSs and enjoy a stable and safe hosting service. Based on your decision, you will also have different Control Panels to choose from. Of course, we can always replace the Operating System if the one you have selected at first does not meet the requirements of the software which you would like to run. We can also upgrade your OS regularly to keep it as secure as possible with our Managed Services upgrade package.
