An Operating System is the software which communicates with the hardware of a computer and works as the intermediary between applications and the hardware, which includes peripherals such as a printer, a mouse or a keyboard. When you run an application, it sends 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). Similar to a personal computer, hosting servers also use an Operating System that serves as a host for all of the software installed on them, including script applications or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be created on a physical one, so you will be able to 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 pick one of our VPS server plans, you'll have as many as three different Operating Systems to choose from - CentOS, Debian and Ubuntu. They're all Linux releases and we offer them instead of offering just a single OS, as the apps that you might want to run on the server could have specific requirements about the software environment. Each one of these three has some pros regarding the available plans that you can later install, but what is common between them is that they're really stable and reliable and have huge communities that support them. The internet hosting Control Panel options for the VPS accounts depend on your OS choice, so as to provide you with more flexibility. In case 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 a matter of minutes. We also offer the option to maintain 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 will find three Operating Systems on the order page as we want to give you a broader choice for the system environment on the machine as different applications may have specific requirements. CentOS, Ubuntu and Debian contain different modules developed by their large support communities, so you can select any of these OSs and enjoy a stable and secure hosting service. Depending 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 which you'd like to run. We can also update the OS routinely to keep it as risk-free as possible with our Managed Services upgrade package.
