Summary using one IoT reference architecture
The best way to summarize what we have explained in this book's chapters is to go through one E2E IoT solution architecture and highlight where you can find more information about each component or layer of that E2E architecture in the chapters.
As stated throughout the book, the concepts we discussed are generic, so if you are using the Microsoft Azure Cloud and its IoT platform, Google Cloud and its IoT platform, or the AWS Cloud and its IoT platform, you will find lots of similarities (that is, the IoT Edge cloud, the IoT Core cloud, managed services, and solutions from the cloud that are used in building different software components and solutions (data analytics, ML, AI, apps, and so on) on their proposed and recommended IoT reference architecture).
For example, here is one Azure IoT reference architecture:
And here is the Google Cloud...
