Serverless technologies are playing an increasingly significant role in modernization efforts. At Capital One, we had the opportunity to completely redesign the engine that generates customers' banking statements as part of the bank's modernization journey. In this talk, we'll share our goals and lessons learned as we built an entirely new solution, which handles everything from the loading of data into Amazon RDS to customer-driven synchronous API calls, using serverless technologies like AWS Lambda and Step Functions. The new, loosely coupled system has allowed us to not only adopt more modern technologies, but to automate most of the formerly manual business processes involved.
