Device Lifecycle#

Managing embedded devices across their operational lifetime — from factory floor to field retirement — requires infrastructure that goes well beyond the firmware itself. Provisioning systems assign identities and credentials to devices at manufacturing time or during first boot. OTA update pipelines deliver new firmware to deployed fleets without physical access. Monitoring systems track device health, detect anomalies, and alert operators before silent failures accumulate into fleet-wide problems.

The tooling and infrastructure for each lifecycle stage depends on the platform architecture — cloud platforms provide managed provisioning services and OTA delivery, while self-hosted deployments build these capabilities from individual components.

Each stage of the device lifecycle introduces its own failure modes and operational patterns. A provisioning system that works for 100 prototype units may collapse at 10,000 production devices. An OTA update that succeeds in the lab can brick devices in the field where connectivity is intermittent and power is unreliable.

What This Section Covers#

• OTA Firmware Updates — Update delivery models, transport protocols, image signing, A/B partition schemes, and rollback strategies for keeping deployed devices healthy.
• Device Provisioning — Zero-touch provisioning, certificate enrollment, identity bootstrapping, factory vs field provisioning, and secure element integration.
• Fleet Monitoring — Device health telemetry, heartbeat patterns, connectivity monitoring, alerting thresholds, dashboard design, and log aggregation from constrained devices.
