Capital One has successfully transitioned to a “serverless-first” operating model over five years, primarily using Amazon Web Services’ Lambda. This shift has significantly improved developer productivity, reduced operating costs, and allowed engineers to focus more on customer-facing outcomes rather than infrastructure management. While not suitable for all workloads, the serverless approach has proven highly effective for event-driven applications, leading to substantial efficiency gains and scalability.
