Sample solution — illustrative reference architecture, not a completed engagement
Cloud Migration for a Multi-Plant Manufacturer
A reference architecture for migrating an on-premises data warehouse to a cloud lakehouse without disrupting plant operations.
The Problem
An aging on-premises data warehouse is becoming a scaling and reliability bottleneck, but the manufacturer can't risk downtime across plants running continuous production.
The Architecture
A phased migration stands up the cloud lakehouse alongside the legacy warehouse, validating outputs in parallel before cutting each plant over individually to minimize risk. Time-travel capability lets teams diff old and new outputs precisely during validation.
The Solution
Each plant is cut over individually once its outputs are validated against the legacy system, with the old warehouse decommissioned on schedule once the final plant is migrated.
Business Value
This pattern is designed to meaningfully reduce infrastructure costs post-migration while improving query performance for plant-floor reporting.
