Fintech Payments Provider — MSSQL to Aurora Migration

Mission-critical database. Couldn't handle peaks. No DR. Failed compliance. Eight weeks later: zero downtime, instant failover, every regulatory box ticked.

A fast-growing fintech company was running a legacy on-premise MSSQL database that could not handle peak transaction periods, lacked disaster recovery, and did not meet fintech compliance requirements. VeUP executed a phased, zero-downtime migration to Amazon Aurora with continuous CDC, multi-AZ failover, KMS encryption, and full audit logging.

In production

• Migration completed in 8 weeks
• Zero unplanned downtime throughout
• Instant failover via Aurora Multi-AZ
• KMS encryption, VPC isolation, RDS Proxy, and audit logging — all compliance requirements met
• Reduced operational and DR costs
