An Operating System is the software which interacts with the hardware of a PC and serves as the intermediary between all the applications and the hardware, including peripherals such as a printer, a computer mouse or a keyboard. When you run an application, it sends requests to the OS using an API (Application Program Interface) and the contact is done via a command line or a Graphical User Interface (GUI). Just like a personal computer, web servers also have an Operating System which functions as a host for any software installed on them, which includes script applications or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be created on a physical one, so you'll be able to install a guest OS on it and have a different system environment compared to the physical server host OS.
Multiple OS in VPS Servers
If you decide to go for one of our VPS server plans, you will be able to select one of the three Linux releases that we offer for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most well-known and most dependable server OSs available and we offer them in order to give you a choice for the software environment of your machine if you intend to install some app with specific requirements regarding 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 may use will depend on the OS that you've selected. We leave the possibility to replace the server Operating System open, so when you want to use an app 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 on a weekly basis by installing all of the security updates that may be released.
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 absolutely free and they won't increase the price of your new hosting server, but also because they are outstandingly secure and stable. Each one of them is supported by a large community of developers, so you'll be given the option to choose from thousands of software packages that you can install on your server in case the application that you want to employ 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 since we want to give you as much flexibility as possible, we offer a couple of OSs and multiple Control Panels. If you get a server with a certain OS, we could change it upon request in the event that it turns out that you'll need a different one. We can also keep the OS updated weekly as a part of the additional Managed Services upgrade.
