Summary
We covered a lot of interesting topics in this chapter. So, let’s go through them once more to refresh our memory. We started by discussing the limitations of our present Raspberry Pi MQTT broker and then looked at the advantages of an MQTT broker, which can be hosted and accessed through the internet. Then, we discussed two options that can help us take our MQTT broker global and learned how to set up each and test them using a simple Node-RED flow on our Raspberry Pi.
We are almost at the finish line! We have covered a lot of content throughout this book. In the next chapter, we will cover the topics that will assist you in answering a very important question: What next?
