An Operating System is the software which interacts with the hardware of a computer and functions as the intermediary between applications and the hardware, including peripheral devices such as a printer, a mouse or a keyboard. When you run an app, it sends requests to the OS through an API (Application Program Interface) and the contact is done through a command line or a Graphical User Interface (GUI). Just like a personal computer, web servers also use an Operating System which serves as a host for all the software installed on them, including script apps or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be generated on a physical one, so you will be able to install a guest OS on it and have a different system environment compared to the physical server host Operating System.
Multiple OS in VPS Hosting
In case you decide to buy one of our virtual private server plans, you'll be able to opt for one of the three Linux releases which we provide for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most widely used and most stable 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 would like to install some application with particular requirements regarding the packages that need to be present on the server. We also offer three web hosting Control Panels and which one of them you could use will depend on the OS that you have chosen. We leave the chance to replace the server Operating System open, so if you want to use an application that requires an OS different from the one you have, we can always re-install the VPS. We can also keep the OS up-to-date on a weekly basis by installing all the security updates which may be released.
Multiple OS in Dedicated Web Hosting
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're free so they will not increase the price of your new server, but also because they are outstandingly secure and stable. Each of them is backed up by a big community of developers, so you will be able to choose from countless software packages that you can install on your server if the application that you intend to work with has specific requirements. The Operating System will also determine what web hosting Control Panel you can use because the Control Panels that we offer are compatible with 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 can change it upon request in case it turns out that you will need alternative one. We could also keep your OS updated on a weekly basis as part of the additional Managed Services upgrade.
