An Operating System is the low-level software which manages a PC. It takes care of the way the hardware functions, the communication with peripheral devices for instance a monitor, a printer or a keyboard, the allocation of memory between various applications, and the prioritization of applications when multiple ones run at once. Every program which is installed on a laptop or a desktop functions by sending requests to the OS for different services by using an application program interface (API). The interaction with the OS can be performed using a Graphical User Interface (GUI) or a command line. In the web hosting field, the OS is what controls a web server and all the software installed on it, which includes not only website scripts, but also any other application for example a VOIP or a game server. In case there're virtual machines created, they use a guest OS that runs on the server host OS.
Multiple OS in VPS
If you pick one of our virtual private server plans, you will have as many as 3 different Operating Systems to choose from - CentOS, Debian and Ubuntu. They're all Linux distributions and we offer them rather than offering just one OS, since the apps that you may want to run on the server could have specific requirements regarding the software environment. Each of these three has certain advantages in terms of the available packages that you can later install, but what's common between them is that they are very secure and reliable and have vast communities which support them. The web hosting Control Panel options 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 a different one later, our tech support team can easily reinstall the VPS with the new one in a couple of minutes. We also offer the option to keep the Operating System on your server up-to-date weekly.
Multiple OS in Dedicated Hosting
The dedicated servers that we offer come with as many as 3 different Operating Systems since we want to give you more versatile solutions that will permit you to install and run any type of web software irrespective of its system requirements. Your options are CentOS, Debian and Ubuntu and these 3 OSs are some of the most stable and secure ones, not mentioning that they don't have any license fees. All three have numerous developers that have created a large number of software packages that you could install and use on your server. We also offer three hosting Control Panels and which one you can use is determined by the Operating System that you choose when you sign up. In case you need a different OS subsequently, it won't be a problem because we can always reinstall your machine. With our Managed Services package we can also keep your OS secure by updating it every week with all patches that are available for it.
