Unified Namespace
Discover the Unified Namespace’s role as a central hub for shop floor data in
UMH.
2 minute read
The Unified Namespace (UNS) within the United Manufacturing Hub is a vital module facilitating the streamlined flow and management of data. It comprises various microservices:
- data-bridge: Bridges data between MQTT and Kafka and between multiple Kafka instances, ensuring efficient data transmission.
- HiveMQ: An MQTT broker crucial for receiving data from IoT devices on the shop floor.
- Redpanda (Kafka): Manages large-scale data processing and orchestrates communication between microservices.
- Redpanda Console: Offers a graphical interface for monitoring Kafka topics and messages.
The UNS serves as a pivotal point in the UMH architecture, ensuring data from shop floor systems and sensors (gathered via the Data Connectivity module) is effectively processed and relayed to the Historian and external Data Warehouses/Data Lakes for storage and analysis.
