Practical Internet of Things Security - Second Edition

Guarding against unplanned equipment failure 

Availability calculations include planned and unplanned maintenance within your IoT systems. If an IoT device, gateway, or other component fails unexpectedly, there may or may not be a failover target that can take up the slack. This is especially important if your IoT devices are not sensors, but robotics, connected farm equipment, or other operational equipment. 

Predictive maintenance techniques can help identify anticipated faults in equipment, and allow you to swap that equipment out on your own terms. Doing so can increase uptime and reduce overall costs associated with repairs.

Predictive maintenance is a data analytics function, and typically requires the instrumentation of your IoT assets, ...
