Each and every desktop or notebook or server is run by an Operating System - the low-level program which interacts with the hardware equipment, including peripherals such as a mouse or a printer, and any apps that are present on the system. Any program input using a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the Operating System. On a web server, each app runs within the parameters set by the OS as well - priority, physical memory, processing time, etcetera. This goes for both standard website scripts and server-side software such as a media server. When a virtual server is set up on a physical one, there can be two different Operating Systems, called guest OS and host OS, so that you'll be able to set up a different software environment on the very same machine.
Multiple OS in VPS Hosting
In case you decide to purchase one of our virtual private server plans, you will be able to select one of the three Linux distributions that we supply for the Operating System of the servers - CentOS, Ubuntu and Debian. They are among the most widespread and most reliable server OSs out there and we offer them in order to give you a choice for the software environment of your machine in case that you would like to install some app with specific requirements with regards to the packages that must be present on the web hosting server. We also offer three web hosting Control Panels and which one of them you'll be able to use will depend on the OS that you've chosen. We leave the possibility to replace the server Operating System open, so if you want to use software that requires an OS different from the one that's already present, we can always re-install the VPS. We can also keep the OS up-to-date weekly by installing all the security updates that may be available.
Multiple OS in Dedicated Web Hosting
We offer three Operating Systems with our dedicated server packages - CentOS, Ubuntu and Debian. They are all different Linux distributions and we offer them not only because they are 100 % free so they won't increase the cost of your new hosting server, but also because they are outstandingly secure and stable. Each one of them is supported by a large community of developers, so you will be able to choose from many hundreds of software packages that you could install on your server in case the app that you would like to use has specific requirements. The Operating System will also determine what hosting Control Panel you can use because the Control Panels that we offer are compatible with particular OSs only and because we want to give you as much freedom as possible, we offer multiple OSs and multiple Control Panels. If you get a server with a certain OS, we will change it upon request in the event that it turns out that you will need alternative one. We could also keep your OS updated on a weekly basis as part of the useful Managed Services upgrade.
