A private cloud is a cloud that is provisioned and managed on-premise by an organization. The private cloud is deployed using an organization’s own hardware to leverage the advantages of the private cloud model. Through VMM, an organization can manage the private cloud definition, access to the private cloud, and the underlying physical resources.
In VMM, a private cloud provides the following benefits:
¨ Self service—Administrators can delegate management and usage of the private cloud while retaining the opaque usage model. Self-service users do not need to ask the private cloud provider for administrative changes beyond increasing capacity and quotas as their needs change.
¨ Resource pooling—Through the private cloud, administrators can collect and present an aggregate set of resources, such as storage and networking resources. Resource usage is limited by the capacity of the private cloud and by user role quotas.
¨ Opacity—Self-service users have no knowledge of the underlying physical resources.
¨ Elasticity—Administrators can add resources to a private cloud to increase the capacity.
¨ Optimization—Usage of the underlying resources is continually optimized without affecting the overall private cloud user experience.
