Juspay Achieves Sub-Millisecond Latency and 80% Cost Savings with Amazon ElastiCache and RDS for MySQL

Juspay, a payment processing company, transformed their architecture to handle transaction peaks using Amazon ElastiCache and Amazon RDS for MySQL. The system processes 7.6 million transactions per hour during peak events, achieves sub-millisecond latency, and reduces infrastructure costs by 80%. Juspay implemented the Command Query Responsibility Segregation (CQRS) pattern with Amazon ElastiCache as a write-back cache to handle traffic spikes while maintaining consistency and reducing costs.
