In a private cloud, the infrastructure is provisioned for a single organization or corporation. There is no concept of resource sharing or pooling outside of the owner's own infrastructure. Within the premises, sharing and pooling are common. A private cloud exists for a number of reasons, including security and assurance. That is, to guarantee information is confined solely to systems managed by the customer. To be considered a cloud, however, certain aspects of cloud-like services must exist, such as virtualization and load balancing. A private cloud may be on-premises or it may be dedicated machinery provided by a third party exclusively for their use.
