💼 Scenario
SmartCity is a municipal government implementing a smart city initiative that will deploy 50,000 IoT sensors across transportation, environmental monitoring, public safety, and utilities systems. The sensors will generate an estimated 5 TB of data daily from traffic cameras, air quality monitors, water flow sensors, energy grid meters, and emergency services GPS trackers.
The city's current IT infrastructure consists of traditional relational databases and batch-processed reporting systems designed for monthly administrative reports. The smart city initiative requires real-time traffic signal optimization, air quality alerts to citizens, water leak detection, energy load balancing, and emergency response coordination.
Data architecture must support multiple analytical patterns: real-time streaming for operational responses, time-series analysis for trend detection, geospatial analysis for location-based services, and batch processing for policy planning reports. Privacy is a concern as some sensors (traffic cameras) can identify individuals, and the city council requires that citizen privacy be protected by design. The architecture must also support data sharing with university researchers and federal agencies.
