An Operating System is the low-level software which controls a computer. It takes care of the way the hardware functions, the communication with peripherals such as a monitor, a printer or a keyboard, the allocation of memory between various applications, along with the prioritization of applications when several run at once. Any program that's installed on a PC operates by sending requests to the OS for different services via an application program interface (API). The interaction with the OS can be done using a Graphical User Interface (GUI) or a command line. In the Internet hosting world, the OS is what controls a server together with any software installed on it, which includes not only website scripts, but also any other application such as a VOIP or a game server. When there are virtual machines created, they use a guest OS which is run on the 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 select one of the three Linux distributions that we supply for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most widely used and most reliable server OSs out there 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 particular requirements in terms of the packages that should be present on the server. We also offer three hosting Control Panels and which one of them you can use depends on the OS that you've selected. We leave the option to change 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 which may be released.

Multiple OS in Dedicated Servers

The dedicated server packages that we offer come with three different Operating Systems to choose from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they are also considered to be among the most stable and secure OSs. We offer three different ones since each one of them is backed by a separate community. The packages which you can add on your web server are different and this could matter if you want to install some piece of software with particular requirements for the hosting environment. In this light, the internet hosting Control Panel that you can select for the dedicated server also depends on the Operating System that you'll select. You can choose any of the three Operating Systems during the order process, but if necessary, we can always install the server anew with another one upon your request. As an optional service that you could add to the package any time, we can update the OS on a regular basis to keep it as secure as possible.
