Over the past three years, FINRA CAT built and optimized a large financial services database. The Consolidated Audit Trail (CAT) runs at massive size and scale, consuming more than 600 petabytes of storage as it pieces together 400+ billion events each day from market exchanges and broker-dealers. Learn how FINRA built a dynamic, cost-efficient architecture that scales to meet the volatile needs of the system, requiring an average of 130,000 compute nodes per day. Explore the architectural patterns and AWS services used, including Amazon EMR, Amazon Athena, and AWS KMS, and learn how FINRA improved performance and reduced costs.
