An Operating System is the basic software that manages a PC. It controls the way the hardware behaves, the communication with peripherals like a monitor, a printer or a keyboard, the allocation of memory between all the applications, along with the prioritization of applications in case multiple ones run concurrently. Any program which is installed on a notebook or a desktop works by sending requests to the OS for different services by using an application program interface (API). The communication with the OS can be done using a Graphical User Interface (GUI) or a command line. In the hosting field, the Operating System is what commands a web hosting server as well as 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. When there are virtual machines created, they employ a guest OS that runs on the server host OS.
Multiple OS in VPS Servers
In case you select one of our VPS server packages, you will have three different Operating Systems to select 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 might want to run on the server could have specific requirements regarding the software environment. Each of these three has some pros regarding the available packages that you can eventually install, but what's common between them is that they're very secure and dependable and have large communities that support them. The hosting Control Panel alternatives for the VPS accounts depend on your OS choice, in order to give you more flexibility. In case 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 just a few 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 plans that we offer come with as many as 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 regarded as the most dependable and safe OSs. We offer three different ones because each of them is supported by a different community. The packages that you could add on your server are different and this may matter if you want to install some piece of software with particular requirements regarding the hosting environment. In this light, the web hosting Control Panel which you can select for the dedicated server also depends on the Operating System that you will select. You may choose any of the three Operating Systems during the order process, but if necessary, we can always install the server anew with a different one upon your request. As an optional service that you can add to the package whenever you want, we can update the OS on a regular basis in order to keep it as secure as possible.
