24-jurisdiction operations supported with appropriate data residency

Cost optimization: 18% reduction via cloud arbitrage

The challenge

A global bank with operations in 24 jurisdictions had varied data-residency requirements + concentration-risk concerns. Single-cloud was untenable.

What we built

Workload-routing framework: each workload classified by data sensitivity, regulatory requirements, and cost profile, then routed to AWS or Azure accordingly. Common identity, observability, and security patterns across both clouds.
