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 service is reliable solution on which resources such as RAM, disk space, database are being hosted on highly scalable and flexible failover protected multiple server infrastructure.It delivers a level of redundancy to compensate for situations like a failure of power or hard drive.
