Case Study: Capital One achieves faster, lower-cost core banking modernization with Serverless Inc

Capital One reduces mainframe cost by 50% with Serverless Inc

Serverless Inc worked with Capital One to address the challenge of innovating on top of decades-old core banking mainframe systems. The legacy architecture was costly, slow to change, and made it difficult to create new customer-facing products and meet evolving regulatory requirements, all while mainframe operational costs were increasing annually.

The solution implemented by Serverless Inc involved creating a read replica of the mainframe database by streaming data from its commit log to a new, fast data environment. This event-driven architecture unlocked the data for real-time analytics and new microservices without disrupting the core transactional systems. This approach by Serverless Inc reduced mainframe CPU load by 50%, slashing costs, and dramatically increased agility; a new fraud detection system mandated by regulators was built and deployed in just three-and-a-half weeks.
