Which is a good use for MQTT and pub / sub?
And using pub/sub (like MQTT) allows for multiple downstream consumers easily. Another great use for MQTT is streaming updates to downstream consumers… like a data-feed from a bus or airline company or something, rather than having to poll a REST API for updates.
