Every panel below is live telemetry from a running deployment: MQTT over secure WebSocket, terminated and authenticated at the CDN edge, routed through the Sentinel L7 proxy into sharded brokers with inline threat inspection. Right now it is holding a sustained six-figure connection load.

The browser fetches a short-lived JWT from /jwt, opens an MQTT-over-WSS session to /wss at the edge, subscribes to its own client-id topic, then publishes a stamped message to that same topic. Because publish and receive share one clock, the measured round-trip is drift-free end-to-end latency through the full path.
The device may only touch its own topic — the same per-identity policy the platform enforces for every connected client.
