An exemplary system includes a front-end component to receive requests for resources in a data center and configured to associate each request with identifying information, to locate one or more resources for each request and to store, in a log file, the identifying information and information about the location of the one or more resources; one or more distributed computation and storage components to acquire log file information and configured to analyze log information to decide if one or more resources associated with one or more requests should be migrated to a data center in a different geographical location; and a location service component to receive decisions made by the one or more distributed computation and storage components and configured to inform the front-end component when a decision causes one or more resources to be migrated to a data center in a different geographical location to thereby allow the front-end component to re-direct future requests for the one or more migrated resources to the data center in the different geographical location. Various other devices, systems and methods are also described. |
