# 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](https://wiki.codeandcompile.com/product-reviews/smart-platforms/hivemq/plc-to-cloud-via-hivemq-edge-+-cloud-opc-ua-mqtt-confluent "mention")\
  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](https://wiki.codeandcompile.com/product-reviews/smart-platforms/hivemq/multi-site-plc-to-cloud-flow-using-hivemq-edge-+-cloud "mention")\
  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](https://wiki.codeandcompile.com/product-reviews/smart-platforms/hivemq/hivemq-edge-to-cloud-ai-pipeline "mention")\
  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](https://wiki.codeandcompile.com/product-reviews/smart-platforms/hivemq/secure-ot-it-data-integration-using-hivemq-edge-and-site-dmz "mention")\
  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.
