- Deploying code in a factory environment exposes it to harsh conditions like dust, grease, and power fluctuations, unlike the controlled cloud environment.
- Physical world constraints challenge cloud-based assumptions, requiring solutions like idempotency in physical actions to prevent damage.
- Offline-first design is crucial in industrial settings for autonomous operation during network outages.
- Time synchronization issues in hardware can lead to misleading logs and require solutions beyond software fixes.
- Many IoT platforms fail in real-world deployments due to underestimating physical constraints and overestimating network reliability.
- Building resilient systems for the physical world involves embracing constraints, minimizing code, and focusing on recovery over consistency.
