Which complimentary AWS tool produces data-driven business cases to support cloud migration and planning?

Migration Evaluator (formerly TSO Logic) is the correct answer because it provides data-driven recommendations and business cases for AWS cloud migration. It analyzes on-premises infrastructure and usage patterns to estimate potential cost savings and performance improvements on AWS, helping organizations plan their migration strategy. AWS Billing Conductor allows you to customize your billing data for specific customers or business units, but it doesn't create business cases for migration. AWS Billing Console is where you manage your AWS bills and payments; it doesn't offer migration planning tools. Amazon Forecast is a machine learning service for time-series forecasting, not for generating cloud migration business cases.
