Case Study: SumUp achieves zero-downtime global payments scaling with CockroachDB

SumUp processes 1B+ transactions a year with Cockroach Labs

SumUp, a global fintech and mobile point-of-sale company, faced significant challenges scaling its core payments platform. Their legacy PostgreSQL database on AWS RDS had become a performance bottleneck and a single point of failure, risking outages and requiring unacceptable planned downtime for maintenance. They needed a horizontally scalable, always-on, and PCI-DSS compliant solution to support their growth, leading them to evaluate Cockroach Labs' CockroachDB.

Cockroach Labs provided a solution with CockroachDB, a distributed SQL database that enabled a zero-downtime migration with no data loss. The implementation gave SumUp a globally available and strictly consistent platform, eliminating planned downtime for upgrades and providing automatic rebalancing. This resulted in the ability to process over 1 billion transactions per year and handle 10,000 payments per minute at peak traffic, providing a resilient foundation for future global expansion.
