Internet of Things for Architects

By: Perry Lea

Overview of this book

The Internet of Things (IoT) is the fastest growing technology market. Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. An architectural guide is necessary 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 devices. This book encompasses the entire spectrum of IoT solutions, from sensors to the cloud. We start by examining modern sensor systems and focus on their power and functionality. After that, we dive deep into communication theory, paying close attention to near-range PAN, including the new Bluetooth® 5.0 specification and mesh networks. Then, we explore IP-based communication in LAN and WAN, including 802.11ah, 5G LTE cellular, Sigfox, and LoRaWAN. Next, we cover edge routing and gateways and their role in fog computing, as well as the messaging protocols of MQTT and CoAP. With the data now in internet form, you'll get an understanding of cloud and fog architectures, including the OpenFog standards. We wrap up the analytics portion of the book with the application of statistical analysis, complex event processing, and deep learning models. Finally, we conclude by providing a holistic view of the IoT security stack and the anatomical details of IoT exploits while countering them with software defined perimeters and blockchains.

The OpenStack cloud architecture


OpenStack is an open source Apache 2.0 licensed framework used to build cloud platforms. It is primarily an IaaS and has been in the developer community since 2010. The OpenStack Foundation manages the software and has support from more than 500 companies, including Intel, IBM, Red Hat, and Ericsson. We will use OpenStack as a reference architecture for other cloud providers as much of the components and terminology are reused in commercial clouds. 

OpenStack started as a joint project between NASA and Rackspace around 2010. The architecture has all the major components of other cloud systems, including compute and load balancing; storage components, including backup and recovery; networking components, dashboards, security and identity, data and analytics packages, deployment tools, monitors and meters, and application services. These are the components that an architect would look for when choosing a cloud service. 

Architecturally, OpenStack is an interwoven...
