Claim Text:
1. A method for controlling a storage of data among a plurality of regional storage centers operatively coupled through a network in a global storage system, the method comprising steps of: defining at least one dataset comprising at least a subset of the data stored in the global storage system; defining at least one ruleset for determining where to store the at least one dataset; obtaining information regarding a demand for the at least one dataset through one or more data requesting entities operating in the global storage system; and determining, as a function of the at least one ruleset, information regarding a location for storing the at least one dataset among a plurality of regional storage centers having available resources that reduces at least one of (i) total distance traversed by the at least one dataset in serving at least one of the one or more data requesting entities, and (ii) latency of delivery of the at least one dataset to the at least one of the one or more data requesting entities; wherein the step of determining information regarding a location for storing the at least one dataset comprises determining whether a migration of the at least one dataset is worthwhile, and, when it is determined that migration is not worthwhile, continuing the step of obtaining information regarding a demand for the at least one dataset; and wherein the step of determining whether a migration of the at least one dataset is worthwhile comprises determining a new location, L^, for the dataset, among the plurality of regional storage centers having available resources, which satisfies an expression a
