In an embodiment, a data processing system comprises: one or more processors; one or more non-transitory computer-readable storage media storing sequences of instructions which, when executed by the one or more processors, cause the processor to perform: in a local data service, receiving a request for processing data; identifying one or more local policies applicable to the request; based, at least in part, on the one or more local policies, determining whether the request may be processed locally; in response to determining that the request may not be processed locally, transmitting the request to one or more remote brokers to cause the one or more remote brokers to determine a remote data service configured to process the request.
