Modernizing Banking Infrastructure for Global Scale
How we migrated a legacy monolithic payment gateway to a high-availability Microservices architecture on Azure Kubernetes Service (AKS).
The Challenge
Our client, a fast-growing digital bank, faced severe performance degradation during peak transaction hours (9 AM - 11 AM daily). Their legacy "on-premise-style" cloud VM setup couldn't scale horizontally fast enough, leading to dropped transactions and customer frustration.
The Critical Barrier
"During payday cycles, our server response time spiked to 8 seconds. We were losing revenue every second our customers couldn't access their funds."
The Solution
We architected a complete "Lift-and-Reshape" migration. Instead of moving VMs, we containerized the application components and deployed them onto Azure Kubernetes Service (AKS) with automated scaling policies.
Core Transformation Steps:
- Zero-Trust Networking: Integrated Azure Front Door with WAF and Private Link to ensure all banking data travels through private tunnels.
- Horizontal Pod Autoscaling: Configured KEDA to scale pods based on transaction queue depth rather than just CPU usage.
- Infrastructure as Code: Every environment (Dev, Staging, Prod) was codified using Terraform, ensuring 100% configuration parity.
