Device Registry
The Device Registry answers the question every other service eventually asks: “is this a real, active device, and what is its current state?” It owns the device record, the certificate that proves a device’s identity, and the twin — the desired vs reported state of each device.
Why a single source of truth
Ingestion, OTA and the dashboards all need a consistent answer about a device. Centralising identity and twin state here keeps those answers authoritative and auditable instead of scattered across services.
