Based on analysis of a workload associated with a throttling key of a client request directed to a first service, a scale-out requirement of the throttling key is obtained at respective resource managers of a plurality of other services which are utilized by the first service to respond to client requests.

Wafer level proximity sensor
Wafer level proximity sensors are formed by processing a silicon substrate wafer and a silicon cap wafer separately, bonding the cap wafer to the substrate wafer, forming an interconnect structure of through-silicon vias within the substrate, and singulating the bonded wafers to yield individually packaged sensors. The wafer level proximity sensor is smaller than a conventional proximity sensor and can be manufactured using a shorter fabrication process at a lower cost. The proximity sensors are coupled to external components by a signal path that includes the through-silicon vias and a ball grid array formed on a lower surface of the silicon substrate. The design of the wafer level proximity sensor passes more light from the light emitter and more light to the light sensor. |
