An Operating System is the fundamental software that controls a PC. It handles the way the hardware behaves, the communication with peripherals like a monitor, a printer or a keyboard, the allocation of memory between various applications, along with the prioritization of apps in case multiple ones run at the same time. Any program which is installed on a computer operates by sending requests to the OS for various services via an application program interface (API). The communication with the OS is possible through a Graphical User Interface (GUI) or a command line. In the hosting world, the Operating System is what commands a web hosting server together with all the software installed on it, which includes not only website scripts, but, in addition every other application such as a VOIP or a game server. In case there're virtual machines created, they use a guest OS which runs on the server host OS.
Multiple OS in VPS Servers
If you decide to acquire one of our VPS server packages, you will be able to opt for one of the three Linux distributions which we supply for the Operating System of the servers - CentOS, Ubuntu and Debian. These are among the most widespread and most dependable server OSs out there and we offer them so that you have a choice for the software environment of your machine in case that you want to install some app with precise requirements with regards to the packages that must 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 picked. We leave the possibility to replace the server Operating System open, so if you want to use an app that requires an OS different from the one that's already present, we can always reinstall the VPS. In addition, we can keep the OS up-to-date weekly by installing any security updates that may be released.
Multiple OS in Dedicated Servers
We offer three Operating Systems with our dedicated server solutions - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they're freely available so they will not increase the low price of your new web server, but also because they are very secure and stable. Each one of them is backed up by a large community of web developers, so you'll be given the option to choose from many hundreds of software packages that you can install on your server in case the application that you would like to employ has specific requirements. The Operating System will also determine what hosting Control Panel you can use as the Control Panels that we offer run on specific OSs only and because we want to give you as much versatility as possible, we offer a couple of OSs and multiple Control Panels. If you choose a server with a given OS, we could change it upon request in the event that it turns out that you need alternative one. We could also keep your OS updated on a weekly basis as a part of the useful Managed Services upgrade.
