Multi-region cloud migration cuts spend 47% and triples release velocity
How a global payments processor consolidated three legacy data centers into a multi-region AWS architecture without a single customer-impacting outage.
Headline result
47%
reduction in cloud spend
The challenge
A global payments processor running on three aging colocation facilities faced rising hardware costs, slow release cycles, and growing regulatory pressure across five jurisdictions. Releases happened monthly, change-failure rates exceeded 18%, and a $12M data-center contract renewal loomed.
Our approach
- 01Workload-by-workload TCO and risk analysis to sequence the migration
- 02Multi-region AWS landing zone with policy-as-code guardrails and per-jurisdiction data residency
- 03Strangler-pattern migration of the core ledger from monolith to event-driven services
- 04FinOps practice stood up in parallel — visibility, accountability, and continuous optimization
- 0524/7 SRE coverage from cutover through stabilization, transitioning to internal team ownership
