Building Durable Serverless IoT Device Workflows using Cloud
summary
Claims a durable, serverless approach that uses Cloud-managed Finite State Machines to orchestrate firmware rollouts with retries, waiting states for offline devices, and task-level visibility. Implementation uses Step Functions + IoT Core + SNS + Lambda and a device simulator; demo runs 50 simulated devices through an A/B firmware update flow with protobuff-to-JSON messaging, handles control-plane rate limits via retries, records per-execution state, and publishes a GitHub repo with the code and diagrams.
