Each personal computer or server is run by an Operating System - the low-level program which interacts with the hardware, including peripheral devices such as a mouse or a printer, and any applications that are present on your 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 goes for both standard Internet site scripts and server-side software such as a media server. In case a virtual server is set up on a physical one, there can be two independent Operating Systems, referred to as guest OS and host OS, so you can set up a different software environment on a single machine.
Multiple OS in VPS Servers
If you decide to purchase one of our VPS server plans, you shall be able to pick one of the three Linux releases that we provide for the Operating System of the servers - CentOS, Ubuntu and Debian. They're among the most popular and most dependable server OSs available and we offer them so that you have a choice for the software environment of your machine in case that you would like to install some application with specific requirements with regards to the packages that must be present on the web server. We also offer three internet hosting Control Panels and which one of them you may use depends on the OS that you've chosen. 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 that's already present, we can always re-install the VPS. In addition, we can keep the OS up-to-date weekly by installing all the security updates which may be available.
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 completely free so they will not increase the cost of your new hosting server, but also because they are extremely secure and stable. Each one of them is backed up by a large community of web developers, so you'll be given the option to choose from countless software packages that you may install on your server in case the app that you want to employ has certain requirements. The Operating System will also determine what internet hosting Control Panel you can use because the Control Panels that we offer run on particular OSs only and because we want to give you as much adaptability as possible, we offer several OSs and multiple Control Panels. If you choose a server with a given Operating System, we could change it upon request in the event that it turns out that you'll need alternative one. We will also keep your OS updated on a weekly basis as a part of the useful Managed Services upgrade.
