Reducing Complexity: Migrating Banking Applications from Hadoop NoSQL to Percona for MongoDB

Many banking platforms still rely on Hadoop-based NoSQL systems that were designed for massive batch processing but have become increasingly complex to operate for modern, low-latency applications. This session shares a real-world modernization journey of evaluating and migrating suitable banking workloads to Percona Server for MongoDB.

We’ll discuss how we identified the right use cases, designed the migration strategy, maintained high availability during cutover, and leveraged Percona’s open-source ecosystem for monitoring, backup, and operational resilience. The session also covers performance improvements, operational simplification, cost considerations, and key lessons learned while running mission-critical banking workloads on an enterprise-grade, open-source MongoDB platform.

Attendees will leave with practical guidance on when a Hadoop-based NoSQL platform is no longer the right fit, how to plan a low-risk migration, and how Percona’s open-source tools can help build a scalable, resilient, and cloud-native data platform for financial services.
