An Operating System is the software which interacts with the hardware of a computer system and is the intermediary between applications and the hardware, which includes peripherals such as a printer, a computer mouse or a keyboard. When you run software, it transfers requests to the OS through an API (Application Program Interface) and the communication is done via a command line or a Graphical User Interface (GUI). Identical to a personal computer, web hosting servers also feature an Operating System that acts as a host for all the software installed on them, which includes script applications or server-side software such as a flash server, a VOIP server, etcetera. A virtual machine can be generated on a physical one, so it is possible to install a guest OS on it and have a different system environment compared to the physical server host Operating System.
Multiple OS in VPS Servers
If you choose one of our VPS server plans, you'll have three different Operating Systems to choose from - CentOS, Debian and Ubuntu. They are all Linux releases and we offer them instead of offering just a single OS, because the applications that you might choose to run on the server could have specific requirements regarding the software environment. Each one of the three has certain advantages in terms of the available packages that you may afterwards install, but what is common between them is the fact that they're really secure and reliable and have vast communities which support them. The hosting Control Panel alternatives 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 a different one later, our technical support team can easily reinstall the VPS with the new one in a couple of minutes. We also offer you the option to keep the Operating System on your server up-to-date weekly.
Multiple OS in Dedicated Servers
The dedicated server solutions that we offer come with three different Operating Systems to select from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they’re also known as the most dependable and safe OSs. We offer three different ones since each one of them is backed by a separate community. The packages that you can add on your web server are different and this may matter in case you need to install some piece of software with particular requirements for the hosting environment. In this light, the internet hosting Control Panel which you can select for the dedicated server also depends on the Operating System that you'll pick. You can pick any of the three Operating Systems throughout the order process, but if needed, we can always set up the server once again with a different one upon your request. As an optional service that you may add to the package at any moment, we can update the OS on a regular basis in order to keep it as risk-free as possible.
