How much extra does multi-region hosting cost?

Multi-region active-active hosting roughly doubles the base bill, with a spread of +50% to +120% depending on architecture.

What you’re paying for:

• 2x compute, running a full Magento cluster in each region.
• Database replication, Aurora Global Database or RDS read-replicas. Adds ~30% to DB bill, plus inter-region data transfer (~$0.02, $0.09 per GB).
• Cache + search replicas, ElastiCache and OpenSearch in each region.
• CDN routing, Fastly multi-shield, Cloudflare Argo, or Route 53 latency routing. ~$100, $500/mo on top.
• DNS health checks + automated failover, minor cost, major value when one region goes dark.

Region cost variance for the same instance family (AWS examples):

• us-east-1 (Virginia): baseline (cheapest).
• us-west-2 (Oregon): +5%.
• eu-west-1 (Ireland): +18%.
• eu-central-1 (Frankfurt): +22%.
• ap-south-1 (Mumbai): +12%.
• ap-northeast-1 (Tokyo): +28%.
• sa-east-1 (São Paulo): +60%.

Most stores don’t need true multi-region. A single region in us-east-1 fronted by Fastly / Cloudflare with global edge cache delivers fast TTFB worldwide for 90% of Magento traffic. Multi-region is for stores with hard requirements: regulatory data residency, compliance, or active-active uptime targets >99.99%.
