Summary
In this chapter, we experienced how to receive the sensor data sent from an edge device and visualize it on the server side.
In this chapter, we used CloudMQTT and Node-RED on the IBM Cloud. Node-RED can run on any cloud platform and on-premises, and you can try to make this kind of application in any environment. That's why remembering this pattern will definitely be useful for your future development with other cloud IoT platforms.
In the next chapter, we will look at a hands-on scenario of making a chatbot application with Node-RED. This will introduce you to a new way of using Node-RED.
