Benefits of MQTT for IoT Messaging and Beyond
summary
MQTT started as a satellite oil‑pipeline protocol and now targets cloud‑scale IoT with concrete features: QoS 0/1/2 for delivery guarantees, last will and retained messages for session continuity, and MQTT 5 adds session/message expiry, user properties and shared subscriptions for cloud native scaling. Demos show a HiveMQ public broker browser client works for quick testing; recommended libraries include HiveMQ and Eclipse Mosquitto and integration paths to Apache Pulsar or Kafka. Claimed scale reaches millions of publishers per minute.
