This book will bridge the spectrum of technologies that comprise edge computing and the IoT. In this chapter, we summarized the domains and topics covered in the book. An architect must be cognizant of the interactions between these disparate engineering disciplines to build a system that is scalable, robust, and optimized. An architect will also be called upon to provide supporting evidence that the IoT system provides a value to the end user or the customer. Here, we learned about the application of Metcalfe's and Beckstrom's laws as tools for supporting an IoT deployment.
In the next chapters, we will learn about communication from sensors and edge nodes to the Internet and cloud. First, we will examine the fundamental theory behind radio signals and systems and their constraints and limits, and then we will dive into near-range and long-range wireless communication.
