Converted the single-region VM and MIG-based web tier into a structurally different multi-region GCP design using two separate VPCs, regional API gateways, Cloud Run services, Firestore databases, Pub/Sub messaging, and Cloud Storage in us-central1 and us-east1. Added global Cloud DNS for traffic entry and cross-region replication links between data and storage services to improve resilience and regional failover.
