How much extra does multi-region hosting cost?

Q: 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%.

Accepted Answer

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%.
