The Fragile Edge: Chaos Engineering For Reliable IoT
FOSS, December 11,2025
Chaos engineering is a great way of detecting possible failures in IoT devices. This technology has evolved well for testing cloud failure, but open source communities are still working towards building an efficient chaos engineering toolkit for testing IoT devices.
Billions of devices around the world today are connected to the internet, performing a variety of tasks in real time. According to IoT Analytics, the total number of IoT devices worldwide is expected to exceed 21 billion by 2025.
While the number of IoT devices continues to grow, they remain vulnerable to malfunctions. Most IoT devices use basic microcontrollers with only a few megabytes of memory. A smart thermostat worth a few hundred rupees has very little processing power. This limits it to handling only a few tasks at a time. As a result, these devices often fail when they encounter unexpected operating conditions.
