An Operating System is the software that communicates with the hardware of a computer system and is the intermediary between all the applications and the hardware, which includes peripheral devices 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 through a command line or a Graphical User Interface (GUI). Just like a personal computer, web hosting servers also use an Operating System that serves as a host for all the software installed on them, including script apps 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 can 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 choose to acquire one of our VPS server plans, you will be able to choose one of the three Linux distributions that we provide for the OS of the servers - CentOS, Ubuntu and Debian. They're among the most popular and most reliable server OSs available on the market and we offer them so that you have a choice for the software environment of your machine in case that you wish to install some app with particular requirements with regards to the packages that should be present on the server. We also offer three hosting Control Panels and which one of them you could use depends on the OS that you have picked. We leave the possibility to replace the server Operating System open, so when you want to use an application that requires an OS different from the one you have, we can always re-install the VPS. In addition, we can keep the OS up-to-date on a weekly basis by installing all the security updates that may be available.
Multiple OS in Dedicated Servers
The dedicated server packages that we offer come with as many as three different Operating Systems to choose from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license fees, but they are also regarded as the most dependable and risk-free OSs. We supply three different ones because each one of them is supported by a separate community. The packages which you could add on your web server are different and this may matter in case you want to install some piece of software with specific requirements about the hosting environment. In this light, the internet hosting Control Panel which you can select for the dedicated server is also determined by the OS that you will choose. You may choose any of the three Operating Systems during the order procedure, yet if needed, we can always install the server once again with another one upon your request. As an additional service that you can add to the package any time, we can update the OS on a regular basis in order to keep it as secure as possible.
