Device Management

Device Management is the control plane for the fleet. It is the source of truth for which devices exist, what state they should be in, and how firmware is rolled out to them. Everything that needs to know “is device X online and which version is it running?” ultimately asks this system.

Responsibility in one sentence

Own the device identity, desired/reported state (the twin), and the firmware lifecycle — and expose that truth to the rest of the platform over a stable API.

System at a glance

Could not build diagram for model "example-iot".

Containers

Device Registry

Source of truth for devices, certificates and the desired/reported twin.

OTA Service

Plans firmware campaigns, targets device cohorts and tracks rollout progress.

Responsibilities

  • Device identity and provisioning records.
  • Per-device certificates and their rotation state.
  • Desired vs reported state (the device twin).
  • Firmware campaigns and rollout progress.

Related workflows

The OTA rollout flow is owned end-to-end by this system:

The provisioning flow brings a new device under management:
