Connecting Things Together, an IoT Data Protocol Story - Dave McAllister, Solace
summary
Built a particulate sensor on an Arduino Uno that sends MQTT into a Solace VMR which converts and forwards data to Pivotal Cloud Foundry over REST, using the free VMR community edition and showing end-to-end feasibility. Scaled from one device to about 20 and found headaches around QoS, load balancing and message ordering; the battery-backed node runs ~4 days and a TI SensorTag lasts ~2 years. Covers protocol tradeoffs (MQTT, CoAP, AMQP, JMS), and using TCP routes into Pivotal Cloud Foundry for non‑HTTP ingress.
