An Operating System is the software that interacts with the hardware of a computer system and functions as the intermediary between applications and the hardware, including peripheral devices such as a printer, a computer mouse or a keyboard. When you run an application, it sends requests to the OS through an API (Application Program Interface) and the contact is done through a command line or a Graphical User Interface (GUI). Just like a personal computer, web hosting servers also use an Operating System which acts as a host for the software installed on them, which includes script applications or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be set up on a physical one, so you'll be able to 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
In case you decide to buy one of our VPS server packages, you'll be able to opt for one of the three Linux distributions that we supply for the OS of the servers - CentOS, Ubuntu and Debian. They're among the most preferred and most reliable server OSs available and we offer them so that you have a choice for the software environment of your machine if you wish to install some application with precise requirements with regards to the packages that must be present on the web server. We also offer three hosting Control Panels and which one of them you can use depends on the OS that you've picked. We leave the chance to change the server Operating System open, so when you want to use an app that requires an OS different from the one you have, we can always reinstall the VPS. We can also keep the OS up-to-date weekly by installing any security updates which may be released.
Multiple OS in Dedicated Servers
In case you decide to obtain one of our dedicated servers, you will find three Operating Systems on the registration page because we want to give you a wider choice for the system environment on the machine as different applications can have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their huge support communities, so you can select each of these OSs and benefit from a reliable and secure web hosting service. Based on your choice, 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 have selected at first does not meet the requirements of the software that you intend to run. We can also upgrade your OS on a regular basis to keep it as risk-free as possible with our Managed Services upgrade package.
