An Operating System is the software which communicates with the hardware of a computer and is the intermediary between all the applications and the hardware, which includes peripherals such as a printer, a computer mouse or a keyboard. When you run an application, it transfers requests to the OS through an API (Application Program Interface) and the communication 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 that functions as a host for the software installed on them, including script apps or server-side software such as a flash server, a VOIP server, etc. A virtual machine can be generated on a physical one, so you could install a guest OS on it and have a different system environment in contrast with the physical server host Operating System.
Multiple OS in VPS Servers
In case you choose one of our VPS server solutions, 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 a single OS, since the applications that you might want to run on the server could have specific requirements regarding the software environment. Each one of these three has some advantages in terms of the available plans that you could later on install, but what is common between them is that they are very secure and reliable and have huge communities that support them. The hosting Control Panel choices for the VPS accounts depend on your OS choice, in order to give you more flexibility. If you order the virtual server with one OS and you need another one later, our technical support team can easily reinstall the VPS with the new one in just a few 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
In case you decide to acquire one of our dedicated servers, you shall find three Operating Systems on the registration page because we want to give you a wider choice for the system environment on your server as different applications may have certain requirements. CentOS, Ubuntu and Debian feature different modules developed by their huge support communities, so you can select any of these OSs and benefit from a reliable and risk-free hosting service. Depending on your choice, you will also have different Control Panels to choose from. Of course, we can always replace the Operating System in case the one you've selected at first doesn't meet the requirements of the software that you'd like to run. We can also update your OS on a regular basis in order to keep it as risk-free as possible with our Managed Services upgrade package.
