Example - connection to a MQTT message broker

So, let's start with a sample use case. Let's connect to an Internet of Things (IoT) sensor data stream. As we haven't covered machine learning so far, we don't analyze the data, we just showcase the concept.

We are using the IBM Watson IoT platform as a streaming source. At its core, the Watson IoT platform is backed by an MQTT (Message Queue Telemetry Transport) message broker. MQTT is a lightweight telemetry protocol invented by IBM in 1999 and became-- an OASIS (Organization for the Advancement of Structured Information Standards, a global nonprofit consortium that works on the development, convergence, and adoption of standards for security, Internet of Things, energy, content technologies, emergency management, and other areas) standard in 2013--the de facto standard for IoT data integration.

Note

Messaging between applications can be backed by a message queue which is a middleware system supporting asynchronous point to point channels in...
