Sammanfattning
This thesis investigates the feasibility of decision provenance, by implementing
it in Carmenta TrafficWatch, a real-time system with a microservice architecture.
We add provenance by creating a separate service that listens to the
message-bus and stores all events and potential changes to those events. This
provenance information can later be queried by other services. To have provenance
of how events interact with each other, we also implement a system for
event aggregation. Our findings indicate that adding provenance to real-time
systems with microservice architecture will not impact the overall performance
of the system significantly, and is a viable solution to add accountability and
increase the understanding of complex systems.
