Private cloud is the cloud computing model, where IT services are provisioned for the dedicated use of a single organization or selected users using private IT infrastructure.
Private cloud enables organizations to uniquely customize their environments as per security requirements. In addition to providing the benefits of a public cloud such as scalability, ease of use, elasticity and rapid development over the network private clouds enable tighter security, predictable costs, increased performance and flexible management.
A private cloud, as a secure cloud environment, is usually preferred over the public cloud when security, control and performance are the top priorities.
