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.

Functional examples (putting it all together)

A collection of sensors alone doesn't have much value until the data they collect is transmitted, processed, or acted upon. That processing can be performed by an embedded controller or sent upstream to a cloud. More hardware is needed to build the system. Typically, the sensors will use established IO interface and communication systems, such as I2C, SPI, UART, SPI, or other low-speed IOs (covered in Chapter 11, Cloud and Fog Topologies). Other devices, such as video systems, will need much faster IOs to maintain high resolution and fast video frame rates. Such IOs would include MIPI, USB, or even PCI-Express. To communicate wirelessly, the sensors will need to be used with wireless transport hardware like Bluetooth, Zigbee, or 802.11. All this requires extra componentry, which we will cover in this section.
