Cloud hosting refers primarily to the use of virtual hardware, network, storage and composite solutions from a cloud vendor. It is enabled through virtualization, whereby the entire computing capacity of an infrastructure or data center is distributed and delivered to multiple users simultaneously. The user uses underlying infrastructure to host its own applications, services and data. For example, a physical server can be virtualized and consolidated to host several cloud servers, all sharing the processor, memory, storage, network and other resources.
Cloud hosting provides untapped flexibility in scaling hosted resources. Moreover, cloud hosting may also combine the capacity of several servers to provide a single cloud hosted server. Some of the cloud hosted solutions are cloud servers, cloud desktops, cloud storage and more.
