Chapter 9: Operational Excellence Pillars for Production-Grade IoT Solutions

Remember that you are on a mission of designing and architecting a production-grade, large-scale IoT solution, not an IoT hobby or fun project. Therefore, you should make sure that your IoT solution is all of the following: fully secure; scalable; reliable; monitored; observed and fully controlled; resilient; fault-tolerant; highly performant; and cost-effective.

IoT solutions are typically complex and contain many systems, components, and layers, so delivering the aforementioned operational excellence aspects is quite challenging.

For example, to make sure your IoT solution is fully secure, you need to start that journey by first securing the IoT devices and microcontrollers, followed by IoT edge devices, IoT gateways, and local networks, before securing communication or the transportation link between the IoT devices and IoT cloud over the wide-area network, and finally securing the IoT backend cloud...
