Every single desktop or notebook or web server is run by an Operating System - the low-level program which interacts with the computer hardware, including peripheral devices such as a mouse or a printer, as well as any apps that are installed on your system. Any program input through a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the OS. On a web server, any application runs within the parameters specified by the OS as well - priority, physical memory, processing time, etcetera. This is valid for both standard website scripts and server-side software like a media server. If a virtual server is set up on a physical one, there can be two separate Operating Systems, named guest OS and host OS, so you'll be able to set up a different software environment on the same machine.
Multiple OS in VPS Servers
In case you decide to go for one of our VPS server plans, you'll be able to opt for one of the three Linux distributions which we supply for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most widespread and most stable server OSs on the market and we offer them in order to give you a choice for the software environment of your machine if you would like to install some app with specific requirements in terms of the packages that need to be present on the hosting server. We also offer three hosting Control Panels and which one of them you can use will depend on the OS that you've picked. We leave the option to change the server Operating System open, so if you want to use an application that requires an OS different from the one you already have, we can always reinstall the VPS. We can also keep the OS up-to-date weekly by installing all the 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 are cost-free so they won't increase the low price of your new hosting server, but also because they are exceptionally stable and secure. Each one of them is backed up by a huge community of web developers, so you'll be given the option to choose from many hundreds of software packages that you could install on your server in case the application that you intend to use has specific requirements. The Operating System will also determine what internet hosting Control Panel you can use because the Control Panels that we offer are compatible with specific OSs only and because we would like to provide you with as much adaptability as possible, we offer several OSs and multiple Control Panels. If you choose a server with a certain Operating System, we will change it upon request in the event that it turns out that you will need another one. We could also keep your OS updated weekly as part of our useful Managed Services upgrade.
