THE REAL PRIVATE CLOUD
physically dedicated and fully control on your hands !
 
Private cloud, which people use to call it as enterprise cloud, is a system of cloud special designed only for one company/institution/community (single tenant). Other definition said private cloud is a computing model that uses resources which are dedicated to your organization.

The different from the public cloud is where your authority is bigger here. You are the administrator of this cloud system. Not a Service Provider! You have right to use this cloud system for your group only, it’s unshared with other part. The hardware, the network and even the platform software is dedicated only for your company. A private cloud shares many of the characteristics of public cloud computing including resource pooling, self-service, elasticity and pay-by-use delivered in a standardized manner with the additional control and customization available from dedicated resources.
