Case Study: Comercia achieves six-nines uptime and 3-second failover with MongoDB Atlas

Comercia achieves 99.9999% uptime with MongoDB Atlas

Comercia Global Payments, a major financial services provider processing €113 billion annually, faced the challenge of building a highly available, proprietary payment gateway to overcome the constraints of its legacy infrastructure. Operating under a strict 99.9999% uptime SLA, the company needed a resilient multi-cloud solution after a single cloud provider outage caused a significant disruption. Comercia chose MongoDB Atlas to create a secure, consistent data layer that could span multiple cloud providers without compromising performance or compliance.

MongoDB implemented a unique active-active cluster spanning Azure, Google Cloud, and AWS, orchestrated entirely by MongoDB Atlas. This solution, supported by MongoDB Professional Services, enabled seamless failover within 2-3 seconds and ensured near-zero downtime during updates. The outcome was that Comercia achieved its six-nines availability target, dramatically reduced operational risk, and built a scalable foundation for rapid expansion across Europe, all while processing billions of operations each month.
