Reservoir Approach

The Reservoir approach is to enable on-demand delivery of IT services at competitive costs without requiring a large capital investment in infrastructure. This approach is inspired by a strong desire to make the delivery of IT services similar to the delivery of common utilities. For example, a common scenario in the electric grid is for one facility to dynamically acquire electricity from a neighboring facility to meet a spike in demand. Just as in other industries in which no single provider serves all customers at all times, the next-generation cloud computing infrastructure should support a model that enables multiple independent providers to cooperate seamlessly to maximize their mutual benefit.[1]
