Private cloud (also called internal cloud or corporate cloud) is a marketing term for a proprietary computing architecture that provides hosted services to a limited number of people behind a firewall. Advances in virtualization and distributed computing have allowed corporate network and datacenter administrators to effectively become service providers that meet the needs of their "customers" within the corporation.
Integration of all hardware resources and creation of a powerful and integrated infrastructure to implement services on Virtual Systems is the most important advantage to use OpenStack Cloud Technology Infrastructure. The major difference between the Cloud Technology and traditional solutions (services implementation on physical servers) is that in traditional solutions, one server was used for each related service in which most of the hardware ability and resource system usage would be left unutilized. However, with Cloud Technology Infrastructure, the server hardware resources and installation of Operating Systems as well as server implementation on Virtual Systems are integrated, which in return, enables substantial decrease and prevention of Hardware resources, energy, and human resources waste.
