IoT and Edge Computing for Architects - Second Edition

Overview of this book

Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. An architectural guide is needed if you want to traverse the spectrum of technologies needed to build a successful IoT system, whether that's a single device or millions of IoT devices. IoT and Edge Computing for Architects, Second Edition encompasses the entire spectrum of IoT solutions, from IoT sensors to the cloud. It examines modern sensor systems, focusing on their power and functionality. It also looks at communication theory, paying close attention to near-range PAN, including the new Bluetooth® 5.0 specification and mesh networks. Then, the book explores IP-based communication in LAN and WAN, including 802.11ah, 5G LTE cellular, Sigfox, and LoRaWAN. It also explains edge computing, routing and gateways, and their role in fog computing, as well as the messaging protocols of MQTT 5.0 and CoAP. With the data now in internet form, you'll get an understanding of cloud and fog architectures, including the OpenFog standards. The book wraps up the analytics portion with the application of statistical analysis, complex event processing, and deep learning models. The book then concludes by providing a holistic view of IoT security, cryptography, and shell security in addition to software-defined perimeters and blockchains.

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.
