A modern lakehouse architecture replacing five legacy warehouses
Five regional data warehouses had grown independently over a decade, each with its own definitions, refresh schedules and access model — reconciling them for a single group-wide report took days.
The challenge
Five regional data warehouses had grown independently over a decade, each with its own definitions, refresh schedules and access model — reconciling them for a single group-wide report took days.
The solution
We designed a governed Microsoft Fabric lakehouse architecture — medallion-layered (raw, cleansed, curated), with a single semantic model feeding every regional and group-level report.
The results
- 5→1
- Regional warehouses consolidated into one lakehouse
- 65%
- Reduction in group-wide reporting turnaround
