Temenos, the world's largest financial services application provider, is leveraging MongoDB to drive innovation in its banking software solutions. The company has adopted a cloud-first, microservices-based infrastructure built with MongoDB, enabling rapid innovation and improving security, performance, and scalability. Temenos' componentized banking approach allows banks to embed components seamlessly into their existing on-premises environments or through a full banking as a service experience. A benchmarking exercise between Temenos Transact and MongoDB demonstrated improved performance and scale, achieving a throughput of 100,000 financial transactions per second with a MongoDB response time under 1ms. This milestone showcases the value of moving from legacy database technology to MongoDB, allowing faster innovation, eliminating technical debt, and simplifying the landscape for financial institutions.
