FinTech Cloud Migration & Payment Engine
Transitioning a mission-critical payment processing engine from on-premise hardware to a secure, PCI-compliant Azure cloud architecture.
The story
behind it
Keyhole Software was commissioned by a global financial firm to migrate their high-frequency payment gateway to Azure. The project required a complete architectural overhaul to support 10 million daily transactions while adhering to strict SOC2 and PCI-DSS compliance standards.
What stood in the way
The client’s physical server infrastructure was reaching end-of-life, causing performance degradation during peak trading hours. Additionally, the existing monolithic code was difficult to scale vertically, leading to excessive hardware costs and maintenance windows that affected global availability.
How we made it happen
We designed a Kubernetes-orchestrated environment on Azure (AKS) that leverages serverless functions for individual payment workflows. By implementing a zero-trust network architecture and automated compliance auditing, we ensured security was baked into every layer of the infrastructure.
Impact that speaks
Cost Efficiency
Optimized resource allocation through containerization led to significant monthly cloud spend reductions.
High Availability
Achieved 'Four-Nines' of availability across global regions using multi-zone redundancy.
Deployment Speed
Automated CI/CD pipelines enabled daily production releases compared to quarterly updates previously.
