For discrete manufacturing (~850 OPC-UA tags, 12 lines), Greengrass + IoT SiteWise anomaly detection moved OEE from 61% to 74% in 90 days — unplanned downtime −18% without replacing MES.
Greengrass v2 for factory floors. July 2026 refresh — Nucleus 2.18.x line, non-root install (2.17), TPM (2.16), SiteWise collector names, SageMaker Edge Manager EOL.
SiteWise multivariate anomaly detection (GA July 2025) is the Lookout for Equipment exit ramp before the 2026-10-07 sunset. July 2026 refresh — when native ML fits, when SageMaker still wins.
OPC-UA → SiteWise Edge on Greengrass v2. July 2026 refresh — MQTT V3 gateways, correct collector component name, DPP closed to new customers, production hardening checklist.
TwinMaker still earns its keep when spatial context beats line charts. July 2026 refresh — SiteWise connectors, Dynamic Scene, AMG (not SiteWise Monitor), and when a 3D twin is overkill.
Connecting your operational technology (OT) network to cloud-scale IT systems on AWS is the foundation of smart manufacturing — but it introduces serious security risks if done wrong. Here are the proven architecture patterns.
AWS IoT Core is the managed MQTT broker at the heart of most AWS Industrial IoT architectures. Here is how to design high-throughput, reliable, and secure MQTT connectivity for factory workloads — from device registration to message routing and cost optimization.
