62. Data, data, data
We’re collecting more data than ever.

63. Every connected device
needs a partner app.
(which is just a dashboard)

87. MQTT
Message Queuing Telemetry Transport

88. ● Lightweight Publish/Subscribe
● Resource constrained devices
○ Unreliable networks
○ High latency
○ Low bandwidth

89. How does it work?
● Publishers/Subscribers
● Pub/Sub decouples clients
● Topics
● TCP/IP
● QoS

90. Applications

92. PubNub vs MQTT

93. MQTT
● Low power embedded devices
● Low bandwidth
● QoS
● No in built security
● Low-high Latency
● Mobile, web and IoT
● High reliability - message delivery
● Security in built
● Real time message delivery
● Highly scalable applications
