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.

This chapter summarized several different sensors and endpoints used in IoT deployments. The IoT isn't about simply connecting a device to the Internet. While that is a key component, the essence of IoT is connecting the analog world to the digital. Essentially, things and devices previously unconnected now have the opportunity to collect information and communicate it to other devices. This is powerful because data that had never been captured now has value. The ability to sense the environment will lead to more efficiencies, revenue streams, and value for customers. Sensing allows for smart cities, predictive maintenance, tracking assets, and analyzing the hidden meaning in massive aggregates of data. Powering such systems is also critical and must be understood by architects. A poorly designed system can lead to too short a battery life, which will end in substantial costs to remediate.

The next chapter will bridge the endpoints to the Internet...
