The Challenge
A wealth management firm serving 200,000+ high-net-worth clients operated a monolithic .NET platform across three on-premise data centres. Quarterly releases took 6+ weeks, scaling for peak tax-season load required over-provisioning 3× baseline, and a single P0 incident in Q2 caused 14 hours of downtime — triggering regulatory scrutiny. Compliance with SEBI, RBI, and GDPR required immutable audit trails, encryption at rest and in transit, and strict geographic data residency.
Engineered Solution
We decomposed the monolith into 23 domain-aligned microservices running on Amazon EKS with Fargate. An API gateway (Kong) handles auth, rate limiting, and routing. PostgreSQL on Aurora with Multi-AZ provides financial-grade durability, while ElastiCache Redis handles session state and market-data caching. A custom chaos engineering pipeline (built with AWS Fault Injection Simulator) validates resilience monthly. All infrastructure is defined as Terraform modules with GitOps delivery via ArgoCD.
