Every personal computer or web server is run by an Operating System - the low-level software that interacts with the hardware, including peripherals such as a mouse or a printer, along with 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 server, every single application runs within the parameters set by the OS as well - priority, physical memory, processing time, etcetera. This is valid for both standard website scripts and server-side software like a media server. If a virtual server is created on a physical one, there can be two separate Operating Systems, named guest OS and host OS, so that you'll be able to set up a different software environment on a single machine.
Multiple OS in VPS Web Hosting
If you decide to acquire one of our virtual private server packages, you shall be able to opt for one of the three Linux releases that we provide for the Operating System of the servers - CentOS, Ubuntu and Debian. They are among the most preferred and most dependable server OSs 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 want to install some app with particular requirements regarding the packages that have to be present on the web 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 option to replace the server Operating System open, so if you want to use an application that requires an OS different from the one that's already present, we can always reinstall the VPS. We can also keep the OS up-to-date on a weekly basis by installing all of the security updates which may be available.
Multiple OS in Dedicated Servers Hosting
If you decide to get one of our dedicated servers, you shall find three Operating Systems on the registration page since we want to give you a wider choice with regard to the system environment on the machine as different applications could have particular requirements. CentOS, Ubuntu and Debian feature different modules developed by their huge support communities, so you can select any of these OSs and benefit from a stable and risk-free Internet hosting service. Depending on your choice, you will also have different Control Panels to choose from. Of course, we can always change the Operating System if the one you've selected at first doesn't meet the requirements of the software that you intend to run. We can also upgrade the OS regularly to keep it as risk-free as possible with our Managed Services upgrade package.
