Freecharge, an Axis Bank digital payments arm, faced scaling issues with their Aerospike database for their identity management system (IMS), handling 1 million daily requests. They switched to Amazon DynamoDB, a serverless, fully-managed service, enhancing performance and reducing costs by 60% compared to Aerospike.

The migration to DynamoDB streamlined data modeling, enabled automatic scaling, and cut operational efforts. Notable aspects included a unified table design, a step-by-step migration for continuous service, and DynamoDB's adeptness at managing traffic surges.
