Each and every notebook or desktop or web server is run by an Operating System - the low-level program that communicates with the hardware equipment, including peripherals such as a mouse and a printer, and any apps that are present on the 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, each and every application runs within the parameters established 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 like a media server. In case a virtual server is created on a physical one, there can be two different Operating Systems, called guest OS and host OS, so that you can set up a different software environment on the very same machine.
Multiple OS in VPS
If you choose to go for one of our virtual private server plans, you'll be able to opt for one of the three Linux distributions which we offer for the Operating System of the servers - CentOS, Ubuntu and Debian. They are among the most widely used and most dependable server OSs on the market 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 app with particular requirements with regards to the packages that must be present on the web hosting server. We also offer three hosting Control Panels and which one of them you'll be able to use will depend on the OS that you have selected. We leave the possibility to replace 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 reinstall the VPS. In addition, we can keep the OS up-to-date weekly by installing any security updates which may be released.
Multiple OS in Dedicated Hosting
In case you decide to get one of our dedicated servers, you shall find three Operating Systems on the order page because we want to give you a wider choice for the system environment on the server as different apps could have particular requirements. CentOS, Ubuntu and Debian come with different modules developed by their vast support communities, so you can select each of these OSs and take advantage of a reliable and risk-free web hosting service. Based on your choice, you will also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you've selected initially does not meet the requirements of the software which you intend to run. We can also upgrade the OS on a regular basis to keep it as risk-free as possible through our Managed Services upgrade package.
