IoT Device Management

When to use

• Designing zero-touch provisioning flows for manufacturing at scale
• Implementing OTA firmware updates with A/B partitions and rollback
• Building device twin / shadow state synchronization between device and backend
• Setting up command-and-control (request-response, fire-and-forget, direct methods)
• Managing fleet operations: group updates, health dashboards, decommissioning

Core principles

1. Provision from hardware roots — private keys belong in secure elements or TPMs; never in firmware flash or environment variables
2. A/B partitions over in-place updates — the inactive slot absorbs the risk; rollback is a reboot, not a crisis
3. Twin delta is the source of truth — desired vs reported gap tells you exactly what the fleet hasn't converged on yet
4. Commands must be idempotent and TTL-bound — offline devices wake up; stale reboot commands should not execute
