# Today's Reality

- Split SCADA stack — Aveva System Platform for validated data; Ignition for KPI monitoring.
- Central Ignition in South Bend holds direct OPC UA sessions to site equipment over the WAN.
- Multiple concurrent OPC UA sessions to the same equipment from different consumers.
- Three legacy IT↔OT integrations bypass ScadaBridge central (Delmia DNC, Camstar MES, custom email service).
- Fragmented data access — consumers reading the same tag can see different values depending on sampling/deadband settings.
