● Lightweight Publish/Subscribe
● Resource constrained devices
○ Unreliable networks○ High latency○ Low bandwidth
How does it work?
● Publishers/Subscribers
● Pub/Sub decouples clients
● Topics
● TCP/IP
● QoS
Applications
PubNub vs MQTT
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
