A Private Cloud is a computing environment which is available to a single organization in a virtualized manner. This can be either implemented internally or can be hosted externally by a Cloud Services Provider. What is important is that the user has complete control and has the advantage of higher security. This model also provides the flexibility of customizing the environment to build a Virtual Data Centre to suit individual customers’ needs. Businesses can have fluctuating demand for Cloud services and the Private Cloud helps in adapting the resources to meet the demand at a very high speed.
