A solutions architect must build a cost-effective business case for migrating an on-premises data center to AWS. The architect will use a configuration management database (CMDB) export of all servers. Which solution is the MOST cost-effective way to analyze that CMDB export for migration planning?

Migration Evaluator (formerly TSO Logic) is specifically designed for this purpose. It analyzes on-premises server data, including CMDB exports, to generate data-driven business cases for AWS migrations, focusing on cost optimization. It provides detailed recommendations and cost comparisons, making it the most cost-effective and efficient solution. The AWS Well-Architected Tool focuses on architectural best practices and operational excellence, not direct cost analysis of on-premises environments for migration. Implementing custom rules with the AWS Price List Bulk API would be a complex, time-consuming, and error-prone development effort, making it less cost-effective than using a specialized tool. AWS Application Discovery Service is primarily for discovering and collecting data from on-premises servers, but it doesn't inherently provide the detailed cost analysis and business case generation that Migration Evaluator offers for CMDB data.
