 This repository contains code to deploy the Cost Optimization Conformance Pack solution across an AWS Organization that utilises Control Tower. It includes an example collection of three custom rules containing best practice cost optimization logic. These will monitor and evaluate your resources to identify their cost optimization compliance posture and consolidate the results back to a single ‘delegated administrator’ account for simplified management.
