Engineering the lifecycle of Granite Field Systems' 2.3 million smart-building devices from 14 manufacturers across four generations: fleet problems such as 180,000 devices past end-of-support, 340,000 gateways sharing one password, 60,000 devices missing from any inventory and 400,000 certificates expiring at once; the eight-segment lifecycle loop from fleet economics and procurement through identity, firmware updates, monitoring and vulnerability response to end-of-life erasure and programme optimisation; and an update campaign rebuilt after one bricked 20,000 controllers, now using A/B partitions with rollback, canary waves and a health gate.

IoT Device Lifecycle Optimisation — The Lifecycle Loop

An expert-level course engineering the whole lifecycle of a multi-million-device IoT fleet — procurement through erasure — for security, cost, and resilience, working the eight-segment lifecycle loop from fleet economics to program optimisation with real fleet, identity, campaign, and compliance queries.

What you'll learn

Build a fleet cost-per-device-year and exposure model that prioritizes program investment by real risk.
Design secure procurement, zero-touch identity provisioning, and certificate lifecycle management at fleet scale.
Architect firmware update campaigns — signed, staged, rollback-capable — that cannot brick a device generation.
Run fleet-scale monitoring, vulnerability triage, decommissioning, and regulatory reporting across heterogeneous device generations.
