The Challenge
A growing payment processor serving merchants across Europe was struggling with on-premise infrastructure. Peak transaction volumes caused system slowdowns, compliance audits were increasingly complex, and the infrastructure team spent most of their time on maintenance rather than innovation.
Our Solution
We designed a phased cloud migration strategy to AWS, prioritizing the payment processing core. The new architecture featured auto-scaling Kubernetes clusters, multi-region failover, and PCI-DSS compliant infrastructure-as-code. Blue-green deployments enabled shipping updates during business hours without risk.
Results Achieved
- Significant reduction in infrastructure costs through right-sizing and auto-scaling
- Improved uptime from ~99.2% to 99.99%+ with multi-region architecture
- Peak capacity increased 10x without performance degradation
- Deployment frequency improved from bi-weekly to multiple times daily
- PCI-DSS compliance streamlined through infrastructure-as-code
