Abstract: Techniques for selectively off-loading workload across multiple data centers are disclosed. For example, a technique for processing a user request in accordance with a multiple data center environment comprises the following steps/operations. A user request is obtained at a first data center. The user request is classified based on one or more classification criterion. At least a portion of a workload associated with the classified user request is off-loaded to at least a second data center to be processed, wherein the off-loading step/operation is at least based on one or more administrative policies associated with at least one of the first data center and the second data center. The workload is processed such that the user request is at least substantially satisfied in accordance with a service level agreement for the requesting user.
