Every single personal computer or web server is run by an Operating System - the low-level program that communicates with the hardware equipment, including peripherals such as a mouse and a printer, together with any apps that are currently installed on the 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 Operating System. On a server, any app runs within the parameters set by the OS as well - priority, physical memory, processing time, etcetera. This goes for both standard site scripts and server-side software such as a media server. When a virtual server is generated on a physical one, there can be two separate Operating Systems, called guest OS and host OS, which means that you can set up a different software environment on a single machine.
Multiple OS in VPS Servers
We offer as many as 3 different Linux releases for the Operating System of our VPS servers - Debian, CentOS and Ubuntu. These are among the most stable and reliable OSs out there and we offer all 3 rather than just one as we realize that you might want to install some software that has specific requirements with regards to the Operating System it will run on. The latter is because each of the three Operating Systems has a huge support community behind it and there're various software packages you could install on the hosting server. Your OS selection will also determine exactly what hosting Control Panel can be installed on the VPS in case you want to use one and because of this we offer multiple Control Panels as well. If you ever decide that you need another OS, our tech support team can quickly wipe the existing one and set up the one that you need. We also offer an optional service to have the OS on your VPS updated weekly.
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 100 % free so they will not increase the low price of your new web server, but also because they are very secure and stable. Each of them is backed up by a vast community of developers, so you will be able to choose from countless software packages that you can install on your server if the application that you want to work with has certain requirements. The Operating System will also determine what hosting Control Panel you can use as the Control Panels that we offer run on particular OSs only and since we want to provide you with as much adaptability as possible, we offer several OSs and multiple Control Panels. In case you get a server with a given OS, we could change it upon request if it turns out that you need another one. We could also keep the OS updated weekly as part of our additional Managed Services upgrade.
