Multinational Investment Bank

Overview

A global investment bank operating a 25-year-old monolithic trading system needed modernization to meet market demands and regulatory requirements. We architected and implemented a microservices-based platform.

The Challenge

The bank's monolithic system faced severe limitations: • Single deployment to entire system took 8 hours • New feature development took 4-6 months • System downtime affecting millions in transactions • Unable to scale components independently • Difficult to maintain and extend aging codebase • Regulatory compliance required complex workarounds

Our Solution

We executed a strategic transformation: • Decomposed monolith into 45+ microservices • Implemented service mesh using Istio for reliability • Built comprehensive CI/CD pipelines with 100+ automated tests • Migrated to Kubernetes for orchestration and scaling • Implemented event-driven architecture using Kafka • Created API gateway for secure external integrations • Established comprehensive monitoring and tracing
