Cloud Based PI System Integration

Industrial data integration is not only about moving tags from OT to IT. In a modern PI System architecture, every connection must be treated as a governed security conduit - with a defined owner, protocol, direction, port, business justification, monitoring requirement and validation evidence. This case study presents a cloud-based PI System integration pattern for multi-area industrial operations: • On-premises remote areas remain in OT/PCN workgroup environments with DCS/PLC systems, redundant OPC DA sources, redundant OPC UA sources and redundant PI OPC Interface nodes where applicable. • Cloud DMZ hosts the PI Server high-availability layer and PI Server Test as controlled aggregation points. • Cloud IT hosts PI AF, PI Vision, SQL/RDBMS integration services and user-facing analytics under one Active Directory domain. • Corporate dashboards are published as approved, curated data products - not by exposing the PI Archive or OT network directly.
