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.

A connected ecosystem

Nearly every major technology company is investing or has invested heavily in IoT and the edge computing space. New markets and technologies have already formed (and some have collapsed or been acquired). Throughout this book, we will touch on nearly every segment in information technology, as they all have a role in IoT.

Figure 1: Example of the architectural layers of an IoT/edge computing system. This is one of the many potential configurations that must be considered by the architect. Here we show the sensor-to-cloud routes through direct communication and through edge gateways. We also highlight the functionality provided by the edge compute nodes and the cloud components.

As illustrated in the preceding figure, here are some of the components within an IoT/edge solution that we will study:

  • Sensors, actuators, and physical systems: Embedded systems, real-time operating systems, energy-harvesting sources...
