The book's strategy

This section of this chapter is mainly to draw your attention to the philosophy or strategy that we will follow and use throughout this book:

• IoT ecosystems and technologies are so massive, and many technologies, solutions, and vendors are available for each IoT solution layer, from devices, sensors, and the edge to the IoT Cloud. Therefore, in this book, we will explain the concepts, and then we will explain the different options available. Finally, to be practical and pragmatic, we might go into the details of one, and only one, of a specific type of technology, solution, or vendor to show real examples where applicable.
• There are many IoT platforms available on the market, as we will explain in a later chapter. We will use one of those IoT platforms, which is the AWS IoT platform, and other AWS services that are related to building an E2E IoT solution. However, and as explained in the previous principle, the book will also touch upon other platforms if needed. For example, if a specific feature or service is not provided by AWS IoT and is provided by another platform, then we will cover that feature using the other IoT platform that provides the service.
• The book is basically for IoT solution architects and designers to design and build production-grade, large-scale IoT solutions, so we will not be able to go over some of the topics that will be covered in this book, such as connectivity, sensors, and devices, in-depth as they will require a dedicated book(s) in order to be covered in full. Having said that, the book will explain the concepts and some details that an IoT architect or designer should know about and understand when designing a complete E2E production-grade, large-scale IoT solution.

For example, when we discuss the IoT cellular connectivity option, we will not delve deep into how it works in terms of radio access networks, telecommunication core networks, and so on. We will instead explain the concepts to some degree so that you understand at a high level how such types of connectivity work and how you can use them as part of your IoT solution blueprint.
