Industrial IoT Systems
Industrial IoT (IIoT) systems connect thousands of sensors on factory floors, power plants, refineries. Data flows from edge devices → gateways → cloud. Challenges: reliability (can't crash), latency (real-time), security (air-gapped networks). Mastery takes 6-8 weeks of embedded systems + networks + cloud. Senior IIoT architects earn 40-60% premium because manufacturing downtime costs $1M/hour. Rare: requires both hardware intuition and cloud expertise (unicorn skill).
What is Industrial IoT Systems
Industrial IoT (IIoT) systems connect sensors, machines, and control systems on factory floors, power plants, refineries, and large-scale infrastructure. Data flows from thousands of sensors → local edge gateway → cloud for storage and analytics. The challenge is real-time reliability, low latency, security in air-gapped networks, and handling massive data streams. Unlike consumer IoT, IIoT demands extreme uptime (99.99%+) because manufacturing downtime costs $1M+/hour. Architecture prioritizes resilience over elegance.
