Financial Institution: Messaging Platform Transformation
Transformed legacy messaging system serving millions of daily transactions into a high-performance, scalable platform that reduced latency by 85% and achieved 99.99% uptime.
The Challenge
15-year-old messaging infrastructure at breaking point
Legacy System Crisis
Critical infrastructure strain
Performance
2,000 msg/sec max
Scalability
Monolithic limits
Our Solution
A comprehensive Kafka-based messaging platform with zero-downtime migration
Next-Generation Architecture
We designed and implemented a cloud-native, highly scalable messaging platform built on Kafka, replacing the legacy monolithic system with a distributed, microservices-based architecture capable of handling exponential growth.
Kafka cluster with 9 brokers across 3 availability zones
Microservices architecture enabling independent scaling and deployment
Event-driven design supporting real-time processing and analytics
Modern Architecture
Cloud-native, scalable, resilient
