Each personal computer or server is run by an Operating System - the low-level program which communicates with the computer hardware, 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 OS. On a web server, every single application runs within the parameters defined by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard site scripts and server-side software like a media server. In case a virtual server is generated on a physical one, there can be two separate Operating Systems, referred to as guest OS and host OS, so you can set up a different software environment on the very same machine.
Multiple OS in VPS Servers
We provide three different Linux distributions for the Operating System of our VPS servers - Debian, CentOS and Ubuntu. These are some of the safest and the most reliable OSs out there and we provide all three of them instead of just 1 since we realize that you may want to install some software with specific requirements with regards to the Operating System it'll run on. The latter is because each of the three Operating Systems has a vast support community behind it and there're various software applications you could install on the server. Your OS selection will also determine exactly what hosting Control Panel can be set up on the VPS in case you wish to use one and for that reason we offer multiple Control Panels as well. In case you decide that you want some other OS, our tech support team can quickly wipe the present one and set up the one that you need. In addition, we offer an optional service to maintain the OS on your VPS updated weekly.
Multiple OS in Dedicated Servers
We offer three Operating Systems with our dedicated server plans - CentOS, Ubuntu and Debian. They are all different Linux distributions and we offer them not only because they are totally free so they will not increase the low price of your new hosting server, but also because they are very secure and stable. Each one of them is supported by a vast community of developers, so you'll be able to choose from thousands 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 as the Control Panels that we offer are compatible with specific OSs only and because we would like to provide you with as much versatility as possible, we offer a couple of OSs and multiple Control Panels. In case you get a server with a certain OS, we can change it upon request in case it turns out that you'll need another one. We will also keep your OS updated on a weekly basis as a part of our additional Managed Services upgrade.
