Zero-Downtime Enterprise Cloud Migration
A high-volume fintech transaction network with legacy on-premises virtualization facing scalability bottlenecks and high operational overhead.
The database processed transactions around the clock, meaning any cutover window had to guarantee zero transaction loss and sub-minute disaster recovery without halting customer traffic.
Engineered an automated AWS landing zone utilizing Amazon Aurora PostgreSQL and ECS Fargate containers. Deployed bi-directional AWS Database Migration Service (DMS) continuous Change Data Capture (CDC) replication for continuous data syncing prior to instantaneous cutover.
- Zero customer downtime during multi-terabyte production cutover
- Automated multi-region failover verified with sub-minute recovery time
- SOC2-compliant audit trails and encryption enforced across all services
Achieved seamless 24/7 business continuity, reduced database query latencies by over 40%, and lowered annual infrastructure hosting expenses.
