IoT and Edge Computing for Architects - Second Edition

By: Perry Lea

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.

Edge hardware architectures

Edge systems can be server-class blades identical to the systems used in enterprise data centers or can be remote far-edge computing devices more akin to a hardened embedded computer. In this section, we explore some of the aspects of the hardware for far-edge appliances that must exist outside of the confines of data center infrastructure.

Dependent on the circumstances and environment, many choices in hardware design exist. You can use an off-the-shelf computing module provided by various OEMs or could chose to build hardware up from a set of discrete components or subsystem modules. Regardless of the method, the end hardware must serve the workload and use cases that are intended to be placed on the edge system.

No matter the architecture, all modern computing devices consist of a compute unit, bus, and memory. This is known as the von Neumann architecture. Whether we are working with a multi-access edge computer in the form of a dual socket...
