# Why Modern Finance Runs on Open Source

**[Percona Blog](https://daily.dev/sources/percona)** · 7 min read · 1 upvotes · 0 comments

## Summary

Financial institutions are increasingly abandoning proprietary databases in favor of open-source alternatives like MySQL, PostgreSQL, and MongoDB. Key drivers include unpredictable licensing costs (74% of DBaaS users cite high costs as their top challenge), vendor lock-in that restricts compliance transparency, and the inability to scale elastically without incurring premium fees. Open source addresses these pain points by offering built-in security and HA features, full auditability for regulators (PCI DSS, GDPR, AML), cloud-native portability across Kubernetes and multi-cloud environments, and predictable economics. The post also positions Percona as an enterprise support layer on top of community open-source databases, offering enhanced distributions, migration services, and managed operations for regulated financial workloads.
