Decoded positions flow through Kafka to a consumer that batch-writes them into Cassandra, while a WebSocket service pushes live updates into channels scoped to each customer and user. Camera streams run through a separate media server, so heavy video traffic never slows down tracking. ## Affordable at fleet scale Looking up a street address for every position of every vehicle through a commercial maps API gets expensive quickly. The platform runs its own geocoding server instead, which keeps running costs flat as the fleet grows. ## Operable by a small team Checkmk with custom plugins watches the Cassandra cluster in depth, and Grafana dashboards let developers diagnose problems themselves without access to the core infrastructure. ![World GPS Tracker on a phone](https://www.webfluentia.com/imgs/work/world-gps-tracker/mobile.jpg) *Flutter app: the fleet across Thailand* // Inside the product ## Inside the product ![Vehicle detail on the live map: speed, distance, fuel, battery and signal (plates and driver details blurred)](https://www.webfluentia.com/imgs/work/world-gps-tracker/gallery-1.jpg) *Vehicle detail on the live map: speed, distance, fuel, battery and signal (plates and driver details blurred)* ![Multi-stream view: up to 16 vehicles side by side, four camera feeds each (video, plates and names blurred)](https://www.webfluentia.com/imgs/work/world-gps-tracker/gallery-2.jpg) *Multi-stream view: up to 16 vehicles side by side, four camera feeds each (video, plates and names blurred)* ![Admin dashboard with fleet status and daily fuel prices (names blurred)](https://www.webfluentia.com/imgs/work/world-gps-tracker/gallery-3.jpg) *Admin dashboard with fleet status and daily fuel prices (names blurred)* ![Flutter app: vehicle list with ignition, speed and signal (plates and device IDs blurred)](https://www.webfluentia.com/imgs/work/world-gps-tracker/gallery-4.jpg) *Flutter app: vehicle list with ignition, speed and signal (plates and device IDs blurred)* // Engineering note > Designing the distributed systems and protocol engines for this IoT platform ensured real-time precision on a global scale. *Naithan WeighCTO, Webfluentia* // Next step ## Have a system to build, fix or run?
