A composite service (200) associated with an analysis of data may be determined (302), the composite service (200) associated with service metadata and including first (126, 128) and second (128, 142, 144, 146) component services having an ordering of execution (200) for the analysis of the data based on the service metadata. The first component service (126, 128), configured to generate a first result, may be deployed (304) to a first service execution environment (104, 124) located at a device layer (102, 106). The second component service (128, 142, 144, 146), configured to generate a second result based on the first result, may be deployed (306) to a second service execution environment (132, 136) located at a device handling layer (130, 134). A request for an analysis result associated with the analysis of data may be received (308, 402). The composite service (200) may be invoked based on an entry point (310, 412). The analysis result may be received (312, 426), and may be based on the second result generated by the second component service (128, 142, 144, 146).
