在与来自 Bluemix Node-RED 的传感器 IoT 设备交谈时，连接到 IoT Foundation 的原因是什么？

Question

I see in the recipes for Bluemix that when I connect my Arduino Uno up with a sensor, that it's asking me to use the catalog boiler plate for IoT foundation (IoTF) rather than just the Node-Red boilerplate. What is the reasoning for this? What more is IoTF providing? Is IoTF providing the MQTT broker? Anything else? (note: I don't want to store any data, so don't want to pay for that)

Answer 1

The difference between the two boiler plates is that the IoTF boiler plate comes with a example flow already deployed, and an instance of the IoTF service bound.

The IoTF service provides a shared MQTT broker and specifies topics to use so you do not clash with other users
