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.

Edge Computing

IoT receives much industry and economic focus because of the number of devices that will eventually be deployed and the amount of data those devices will produce. There are two methods regarding how edge devices and sensors will operate and communicate with the internet:

  • Edge-level sensors and devices will provide a direct path to the cloud. This implies that these edge-level nodes and sensors will have enough resources, hardware, software, and service-level agreements to transmit data across the WAN directly.
  • Edge-level sensors will form aggregations and clusters around gateways and routers to provide staging areas, protocol conversions, and edge/fog processing abilities, and they will manage security and authentication between the sensors and the WAN.

This chapter will detail edge computing. The role of edge computing involves a lot of what we have already learned about communications, but we also need to care for IT management...
