Introduction

Looking for the old Kubernetes Helm stack? See the UMH Core vs UMH Classic FAQ to understand which edition fits your project and the current migration path.

UMH Core is a single Docker container that turns any PC, VM, or edge gateway into an Industrial Data Hub.

Inside that one image you'll find:

• Redpanda – an embedded, Kafka-compatible broker that buffers every message.

• Benthos-UMH – a stream-processor engine with 50+ industrial connectors.

• Agent – a Go service that reads config.yaml, launches pipelines, watches health, and phones home to the Management Console.

• S6 Supervisor – keeps every subprocess alive and starts them in the correct order.

Why teams pick UMH Core

Benefit	What it means in practice
Simple	PLCs, sensors, ERP/MES, cloud services all talk to one Unified Namespace (UNS) instead of point-to-point spaghetti.
Lightweight	Runs on almost everything
No lock-in	100 % open-source stack: Redpanda, Benthos, S6, and much more

Key concepts at a glance

Instance
└─ Core
   ├─ Bridges           # ingest or egest data (ex-"Protocol Converters")
   │   ├─ Read Flow ✅   # read side - Available now
   │   └─ Write Flow 🚧  # write side - Roadmap Item
   │   └─ Connection ✅  # monitors the network connection - Available now
   ├─ Stream Processors 🚧  # Roadmap - transforms messages inside UNS
   └─ Stand-alone Flows ✅  # Available now

• Bridge – connects external systems to the UNS with health monitoring. See Bridges for details. (Read flows available ✅, Write flows in development 🚧)

• Stream Processor 🚧 – transforms messages already inside the UNS. (Roadmap item)

• Stand-alone Flow ✅ – point-to-point when UNS buffering isn't wanted. (Available now)

• Connection ✅ - a continuous network check whether the external system is available. (Available now)

Typical architecture

┌──────── PLC / Device ───────┐
│  OPC UA / Modbus / S7 / …   │
└────────────┬────────────────┘
             │  Bridge (Read Flow)
             ▼
    ┌───────────────────┐
    │ Unified Namespace │
    └───────────────────┘
             │  Bridge (Write Flow)
             ▼
   MQTT broker ▸ Cloud ▸ Historian ▸ Dashboards

Every message first lands in the Unified Namespace, giving you replay, buffering, and reliable data processing. MQTT Brokers, Databases, Historians, Dashboards, etc. then consume the data from that.
