We aim to provide the best possible customer experience by balancing the cost of financial and reputational risk (e.g. OPEX, service unavailability) against customer friction (e.g. service limits, customer downtime). To accomplish this mission, we employ a strategy that includes preventing access to AWS via the sign-up process, detecting fraudulent and abusive behaviors using Machine Learning models and rules, containing risky accounts by limiting access to service resources, investigating suspicious accounts, and remediating fraud and compromise within AWS by cleaning up account resources to recover service capacity.Utility Computing (UC) AWS Utility Computing (UC) provides product innovations — from foundational services such as Amazon’s Simple Storage Service (S3) and Amazon Elastic Compute Cloud (EC2), to consistently released new product innovations that continue to set AWS’s services and features apart in the industry.
