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.

Part 3 – Edge computing

Edge computing brings nontraditional computing power close to the sources of data. While embedded systems have existed in devices for the last 40 years, edge computing is more than a simple 8-bit microcontroller or analog-to-digital converter circuit used to display temperature. Edge computing attempts to solve critical problems as the number of connected objects and the complexity of use cases grows in the industry. For example, in IoT areas we need the following:

  • Accumulate data from several sensors and provide an entry point to the Internet.
  • Resolve critical real-time responses for safety-critical situations like remote surgery or automated driving.
  • Solutions that can manage an overwhelming amount of processing of unstructured data like video data or even streaming of video to save on costs of transporting the data over wireless carriers and cloud providers.

Edge computing also comes in layers as we will...
