This hardware is managed by the so-called hypervisor, a software component that defines the virtual environment and makes available to each VPS a portion of all the physical resources available on the physical server such as CPU, RAM or hard drive. Root rights allow VPS users to install all the applications supported by the chosen operating system, which can consist of web server software, a mail server or more special ones such as eCommerce or blogging systems.
