HiveMQ

Each page builds on the previous one, from simple PLC-to-cloud flows to enterprise-grade, secure OT/IT integration. You can use these guides to:

• Understand how HiveMQ fits into typical industrial architectures
• Design scalable MQTT / UNS-based data pipelines
• Explain OT/IT integration concepts to engineers, IT teams, and management

​

What you’ll find in the sub-pages

• PLC to Cloud via HiveMQ (Edge + Cloud) — OPC UA → MQTT → Confluent
  A foundational flow showing how PLC data is collected via OPC UA, mapped to MQTT using HiveMQ Edge, and forwarded to cloud systems.
• Multi-Site PLC-to-Cloud Flow using HiveMQ Edge + Cloud
  An extension of the basic pattern, demonstrating how multiple sites and Edge instances can feed a centralized cloud or enterprise broker.
• HiveMQ Edge-to-Cloud AI Pipeline
  A use-case-driven example showing how OT data can be consumed by analytics and AI workloads once it is available via MQTT.
• Secure OT/IT Data Integration Using HiveMQ Edge and Site DMZ
  A reference architecture illustrating how enterprises typically separate OT and IT using a Site DMZ (Level 3.5), with HiveMQ Edge and brokers deployed in layers.

Together, these pages provide a progressive learning path — from simple connectivity to enterprise-ready OT/IT integration aligned with UNS and security best practices.
