Case Study: BNP Paribas achieves ultra-low-latency online banking and faster data migration with Hazelcast

BNP Paribas achieves sub-1ms banking responses with Hazelcast

BNP Paribas Bank Polska faced the challenge of migrating customer data from an acquired bank under a strict timeline while simultaneously building a new high-performance, low-latency online banking system. They needed to ensure data integrity during migration and deliver a consumer-grade digital experience without disrupting their stable core banking operations. To address this, they turned to Hazelcast and its in-memory computing platform.

Hazelcast provided a distributed caching layer and in-memory compute capabilities to solve both challenges. The implementation resulted in a 12x faster data reconciliation for the migration and enabled the bank's online systems to achieve sub-1ms response times, handling 84,000 requests per second. This performance boost allowed BNP Paribas to complete the critical data migration over a single weekend with zero downtime, meeting all SLAs and avoiding any disruption to peak-hour operations.
