Active-Active Multi-Region Deployment — 99.999% Availability

The Challenge

Travel marketplace in single US region. APAC bookings had 3s+ latency with 40% cart abandonment. Any US-East outage meant total platform downtime.

✗3+ second latency for Asia-Pacific users
✗40% cart abandonment attributed to slow page loads
✗Single point of failure — us-east-1 outage = total downtime
✗SQL database not designed for multi-region replication

Our Solution

Active-active deployment across 3 AWS regions with Route53 latency-based routing, CockroachDB for multi-region SQL consistency, and CloudFront for global edge delivery.

Deployed EKS clusters in us-east-1, eu-west-1, ap-southeast-1
Migrated PostgreSQL to CockroachDB for multi-region SQL
Configured Route53 latency-based routing with health checks
Set up CloudFront distributions per region with origin failover
Implemented conflict-free booking logic with distributed locks
Results & Impact

Expanded to 15 new APAC markets. Revenue from Asia up 220% in 6 months.
