I recently gave a talk about „Pub / Sub for the masses – An introduction to MQTT“ in Vienna at the Global Iot Day 2015 Event. It was a very short talk and I only covered the most important aspects of MQTT.

It’s available on Youtube and you can see it in full length below. Unfortunately the microphone had a loose contact, so I apologize for the bad sound. The audience had some great questions afterwards, so make sure to watch the whole video. Enjoy!

The slides are also available on Slideshare, you can see it below:
