Every single notebook or desktop or web server is run by an Operating System - the low-level program which communicates with the hardware, including peripherals such as a mouse or a printer, as well as any applications 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, every single app 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. If a virtual server is generated on a physical one, there can be two independent Operating Systems, named guest OS and host OS, so that you'll be able to set up a different software environment on a single machine.
Multiple OS in VPS Servers
In case you decide to acquire one of our VPS server packages, you shall be able to opt for one of the three Linux distributions which we provide for the Operating System of the servers - CentOS, Ubuntu and Debian. These are among the most well-known and most dependable server OSs available on the market and we offer them in order to give you a choice for the software environment of your machine in case that you need to install some application with particular requirements in terms of the packages that have to be present on the web server. We also offer three internet hosting Control Panels and which one of them you can use depends on the OS that you have chosen. We leave the chance 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. 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 packages - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they are freely available so they won't increase the low price of your new server, but also because they are extremely secure and stable. Each one of them is backed up by a large community of developers, so you'll be given the option to choose from a myriad of software packages that you can install on your server if the app that you intend to employ has certain requirements. The Operating System will also determine what hosting Control Panel you can use because the Control Panels that we offer run on specific OSs only and because we would like to give you as much flexibility as possible, we offer a couple of OSs and multiple Control Panels. In case you get a server with a given Operating System, we could change it upon request if it turns out that you will need another one. We could also keep your OS updated on a weekly basis as a part of the additional Managed Services upgrade.
