Deploying IoT at scale is less about sensors and more about operational reliability. After connecting over a thousand devices across three manufacturing plants, here are the patterns that matter.
Start with the data model
Before choosing hardware, define your topic hierarchy and time-series schema. A clear MQTT structure — site/line/device/metric — saves months of refactoring.
Plan for connectivity gaps
Field networks fail. Design gateways to buffer messages locally and replay when connectivity returns. Your cloud pipeline should be idempotent.
Observability from day one
Device health, message lag, and gateway uptime should be on the same dashboard as production metrics. Alerts should escalate with context — not just "sensor offline."
Security is not optional
Mutual TLS, device certificates, and rotated credentials are baseline requirements for industrial deployments. Budget time for provisioning workflows early.
