Each and every personal computer or server is run by an Operating System - the low-level software which interacts with the hardware equipment, including peripheral devices such as a mouse or a printer, as well as any apps that are present 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 app runs within the parameters defined by the OS as well - priority, physical memory, processing time, etcetera. This is valid for both standard Internet site scripts and server-side software such as a media server. In case a virtual server is generated on a physical one, there can be two different Operating Systems, referred to as guest OS and host OS, which means that 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 purchase one of our VPS server packages, you shall be able to choose one of the three Linux releases which we provide for the Operating System of the servers - CentOS, Ubuntu and Debian. They are among the most well-known and most stable server OSs out there and we offer them in order to give you a choice for the software environment of your machine if you wish to install some application with specific requirements with regards to the packages that must be present on the web hosting server. We also offer three internet hosting Control Panels and which one of them you can use depends on the OS that you've chosen. We leave the possibility to change the server Operating System open, so if you want to use software that requires an OS different from the one you already have, 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 are all different Linux distributions and we offer them not only because they are 100 % free so they will not increase the cost of your new hosting server, but also because they are exceptionally secure and stable. Each of them is supported by a huge community of developers, so you'll be given the option to choose from many hundreds of software packages that you may install on your server if the app that you want to work with has certain requirements. The Operating System will also determine what web hosting Control Panel you can use since the Control Panels that we offer run on particular OSs only and because we would like to provide you with as much flexibility as possible, we offer several OSs and multiple Control Panels. If you choose a server with a certain Operating System, we can change it upon request in case it turns out that you'll need alternative one. We can also keep the OS updated on a weekly basis as a part of our additional Managed Services upgrade.
