A cloud server is a shared section of a server. It’s allocated for your use (via a virtual environment) and controlled by the service or cloud provider. On your end, it appears that you are running your own compute and storage space. However—and this is an important point—there are usually a large number of other people using the same compute and storage resources within their own virtualized environment.
With the cPanel/WHM control panel you can create, manage and scale unlimited hosting accounts on your personal virtual server. From managing your websites and emails to starting your own reseller hosting business, the cPanel/WHM control panel gives you the tools to manage your business professionally without the need of any special skills or previous experience.
Rather than being hosted on one single instances of a physical server, hosting is delivered on a virtual partition which draws its resource, such as disk space, from an extensive network of underlying physical servers. If one server goes offline it will have no effect on availability, as the virtual servers will continue to pull resource from the remaining network of servers.
