Approaches presented herein relate to the distribution and processing of stream data in a networked computing environment. A set of streaming data sources can be identified for a given cluster of nodes and the data from those data sources can be tracked, managed, and / or routed to a number of different microservices. Stream distribution and routing (SDR) agents may be used to manage a routing table that includes an identifier for each of the data sources. The individual agents may distribute information about the sensors to individual microservices, which may determine which data streams are relevant and then initiate individual processes and functions using the relevant data streams. Output results from the individual microservices may also be assigned an identifier, which may further be used by the individual agents to route outputs toward their particular microservices, which may then use the outputs from other microservices within their own workstreams.
