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.

Welcome to the world of the IoT. As architects in this new field, we have to understand what the customer is building and what the use cases require. IoT systems are not a fire-and-forget type of design. A customer expects several things from jumping on the IoT train.

First, there must be a positive reward. That is dependent on your business and your customer's intent. From my experience, a 5x gain is the target and has worked well for the introduction of new technologies to preexisting industries. Second, IoT design is, by nature, a plurality of devices. The value of IoT is not a single device or a single location broadcasting data to a server. It's a set of things broadcasting information and understanding the value the information in aggregate is trying to tell you. Whatever is designed must scale or be scalable; therefore, that needs attention in upfront design.

We have learned about the segments of IoT and the projected versus actual IoT growth rates. We also have explored a single commercial use case and seen that IoT and edge computing span multiple disciplines, technologies, and functionalities. These mechanics of developing a commercially viable IoT and edge computing system will require the architect to understand these various segments and how they interrelate.

We now start exploring the topology of an IoT and edge computing system as a whole and then break down individual components throughout the rest of the book.
