Case Study: Nationwide achieves resilient faster payments with MongoDB

Nationwide powers 3 million faster payments at peak with MongoDB

Nationwide, a major UK building society and financial institution, faced the challenge of modernizing its critical faster payments platform to ensure maximum resilience, security, and scalability. Processing millions of high-value transactions daily, any disruption would severely impact the national infrastructure. To build a system that could maintain 24/7 uptime and meet regulatory demands for vendor independence, Nationwide partnered with MongoDB and used MongoDB Enterprise Advanced.

MongoDB provided the solution by powering a dual-cloud, active-active platform stretched across two cloud providers. This allowed Nationwide to run a resilient, self-hosted cluster that writes data simultaneously to both clouds. The implementation was completed in under eight months, resulting in a system that can instantly failover if one cloud fails, ensuring uninterrupted payments. This project, potentially a world-first, delivered unmatched resilience, trust, and automation for Nationwide's critical infrastructure.
