How we migrated legacy systems for a leading financial institution to AWS, reducing server overhead and cutting hosting costs by 60%.
Our financial client had been managing localized server arrays that were difficult to scale, secure, and monitor. The team had high hardware upgrade costs and struggled to maintain strict financial compliance standards (SOC2, PCI-DSS) on their legacy on-premise hardware.
They required a seamless, zero-downtime database and system migration ("Lift & Shift") to a high-availability cloud cluster with automated failover and secure isolations.
| Client: | Finance Firm (Apex Wealth) |
| Services: | DevOps, Infrastructure Automation, Cloud Security Auditing |
| Tech Stack: | AWS (EC2, RDS, S3), Terraform, Ansible, Docker |
| Duration: | 6 Weeks (Planned Phases) |
Wrote Terraform scripts to structure multi-AZ virtual private clouds (VPCs), isolating transaction APIs inside highly secure subnets.
Migrated the primary transaction database to AWS Aurora MySQL with Multi-Availability Zone replication for automated, instant failover protection.
Configured transaction log replication to keep the cloud DB synced with on-prem, completing the DNS switch without taking active users offline.
Eliminated localized physical hardware upkeep, using autoscaling to pay only for active resources.
Highly resilient node configurations prevent failures even if entire cloud regions suffer disruptions.
VPC encryption, automated audit logs, and IAM controls aligned perfectly with financial auditing demands.
