Can combined with REST to provide notifications

Multiple brokers

Standard since October 29th

IoT-friendly “Tricks”

•  Last will & testament

•  Binary payload

•  3 QoS levels

•  Retained messages

•  2 byte overhead

•  Small footprint

•  Low bandwidth

Mobile: MQTT vs HTTPS

Do one thing and do it well!

“I position MQTT as "the UNIX utility of M2M" - deliberately simple, easy to plug

in to other tools, languages, and techniques”

- Andy Piper, Twitter

MQTT is so simple that my children instantly could follow the message flow and suggest

changes

Usages...

MQTT might be in your pocket now

“MQTT is used both inside as inter- process communication and in the cloud

for diagnosis”

- Stefano Costa, Bluewind

Credo: “Use it as a protocol. Provide scaling and security as you need”

“Wiring together hardware devices, APIs and online services in new and interesting ways [...] focus on the task at hand and not worry about the plumbing”

- Nick O’Leary, IBM

"Just as a spreadsheet lets you to play around with numbers, Node-RED is a tool that's good

for playing around with events”

- Dave Convay-Jones, IBM
