An Operating System is the software which communicates with the hardware of a computer system and works as the intermediary between applications and the hardware, including peripherals such as a printer, a computer mouse or a keyboard. When you run an application, it transmits requests to the OS using an API (Application Program Interface) and the contact is done via a command line or a Graphical User Interface (GUI). Identical to a personal computer, web servers also feature an Operating System that acts as a host for any software installed on them, which includes script apps or server-side software such as a flash server, a VOIP server, etcetera. A virtual machine can be generated on a physical one, so you can install a guest OS on it and have a different system environment in contrast to the physical server host Operating System.
Multiple OS in VPS Hosting
If you select one of our virtual private server packages, you'll have three different Operating Systems to pick from - CentOS, Debian and Ubuntu. They're all Linux distributions and we offer them rather than offering just one OS, as the apps that you might choose to run on the server could have specific requirements about the software environment. Each one of the three has certain advantages with regard to the available packages that you can afterwards install, but what's common between them is the fact that they are really secure and dependable and have large communities which support them. The hosting Control Panel alternatives 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 another one later, our tech support team can easily reinstall the VPS with the new one in just a few minutes. We also offer you the option to maintain the Operating System on your server up-to-date weekly.
Multiple OS in Dedicated Web Hosting
In case you decide to obtain one of our dedicated servers, you'll find three Operating Systems on the registration page as we want to give you a larger choice regarding the system environment on the machine as different apps may have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their large support communities, so you can select any of these OSs and enjoy a reliable and secure hosting service. Depending on your decision, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you've selected in the beginning does not meet the requirements of the software which you'd like to run. We can also upgrade the OS on a regular basis to keep it as secure as possible with our Managed Services upgrade package.
