Enterprise AWS Transformation for FinTech

Challenge

The client operated a legacy on-premises infrastructure that was struggling to keep up with growing demand. Their systems experienced frequent downtime during peak trading hours, and the cost of maintaining aging hardware was escalating rapidly. Regulatory compliance requirements added additional complexity to any modernization effort.

Solution

We designed a phased migration strategy using the AWS Migration Acceleration Program. Starting with non-critical workloads, we validated our approach before tackling mission-critical trading systems. We implemented a hybrid architecture during the transition period, ensuring zero downtime. Key services included Aurora for high-frequency transaction processing, ElastiCache for sub-millisecond latency, and AWS WAF for security compliance.

Results

The migration resulted in immediate performance improvements across the board. Transaction processing times dropped by 60%, system availability increased to 99.99%, and the client achieved a 40% reduction in total infrastructure costs. The new architecture also enabled the client to launch new financial products 3x faster than before.
