The problem
Single-region deployment in Ireland was hurting Australian customers with 400 ms latency. Compliance asked for data residency in country. AWS bill was growing faster than revenue.
The solution
Re-platformed onto a region-aware control plane. Per-region data planes in eu-west-1, us-east-1, and ap-southeast-2, with me-central-1 in pilot. Cross-region replication for disaster recovery. FinOps pass on Lambda memory, Graviton, and S3 lifecycle cut spend without dropping headroom.
