HiveMQ

This section brings together a set of practical reference architectures showing how HiveMQ is commonly used in industrial OT/IT environments.

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.

Each article is intentionally architecture-focused and vendor-neutral, reflecting how HiveMQ is deployed in real industrial environments.
