Great explanation. I use MQTT regularly for home automation, and I love the "forgiveness" it gives with sometimes sketchy network connectivity, as well as the great way manufacturers are using it in a "sleep till I need to fire a simple update" technique that conserves battery life in remote devices that may not have mains power available.
Just watching this for the first time. What a great presentation and explanation. Thank you.
Glad you enjoyed it Bob. Thanks for watching!
Very professional explanation + very effective body language technique.

These videos are amazing; very grateful to Walker (and team) and what he is leading. Note for Zac - probably "queue", not "que" for acronym of MQTT
Apparently MQTT no longer even stands for that. MQTT is MQTT now. But thank you!

How does one ensure against broker failure? It is a spof, right?
Clustering.
Pls explain about how the subscriber know if the publisher is loss connection.
It publishes a death certificate. The connection is stateful (It knows if it's good or not)
Start at 2:20
Mqtt broker can be unified name space?
YES!
skip to 2:28 thank me later
Please more tutorials! Thanks
More to come!
Anyone understood the part around 10:57? How can you subscribe with an "outbound" connection?
The subscription response comes back through the connection established by the client through the outbound connection to the broker.
@@4.0Solutions Oh I see, thank you!
