MQTT Broker
The MQTT Broker is where the fleet physically connects. It terminates mutual-TLS sessions, authenticates each device against its certificate, keeps per-client session and QoS state, and routes published messages between devices and the cloud.
Why MQTT
MQTT is built for constrained, intermittently connected devices: tiny frames, persistent sessions, QoS levels for at-least-once / exactly-once delivery, and last-will messages for crash detection. That maps directly onto a fleet of field devices on flaky networks.
