An Operating System is the low-level software which manages a computer. It handles how your hardware operates, the communication with peripherals including a monitor, a printer or a keyboard, the allocation of memory between your applications, and the prioritization of applications in case multiple ones run concurrently. Any program which is installed on a computer functions by sending requests to the OS for various services via an application program interface (API). The interaction with the OS can be done through a Graphical User Interface (GUI) or a command line. In the web hosting world, the Operating System is what controls a hosting server together with all the software installed on it, which includes not only website scripts, but also every other application for instance a VOIP or a game server. When there're virtual machines created, they work with a guest OS which is run on the server host OS.
Multiple OS in VPS Web Hosting
If you choose one of our virtual private server solutions, you'll have 3 different Operating Systems to select from - CentOS, Debian and Ubuntu. They are all Linux distributions and we offer them rather than offering just a single OS, since the applications that you might want to run on the server could have specific requirements regarding the software environment. Each one of the three has some pros in terms of the available packages that you may later on install, but what is common between them is the fact that they're really secure and reliable and have huge communities which support them. The hosting Control Panel alternatives for the VPS accounts depend on your Operating System choice, in order to provide you with more flexibility. In case you order the virtual server with one OS and you need a different one later, our technical support team can easily reinstall the VPS with the new one in a couple of minutes. We also offer the option to maintain the Operating System on your server up-to-date weekly.
Multiple OS in Dedicated Servers 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 are cost-free and they won't increase the price of your new hosting server, but also because they are outstandingly stable and secure. Each of them is supported by a vast community of developers, so you'll be given the option to choose from thousands of software packages that you may install on your server if the application that you intend to employ has specific requirements. The Operating System will also determine what web hosting Control Panel you can use as the Control Panels that we offer are compatible with particular OSs only and because we want to provide you with as much freedom as possible, we offer a couple of OSs and multiple Control Panels. In case you get a server with a certain Operating System, we could change it upon request if it turns out that you'll need another one. We will also keep the OS updated weekly as part of the additional Managed Services upgrade.
