Which solution will meet these requirements MOST cost-effectively?
Use AWS Well-Architected Tool to import the CMDB data to perform an analysis and generate recommendations.
Use Migration Evaluator to perform an analysis. Use the data import template to upload the data from the CMDB export.
Implement resource matching rules. Use the CMDB export and the AWS Price List Bulk API to query CMDB data against AWS services in bulk.
Use AWS Application Discovery Service to import the CMDB data to perform an analysis.
Explanations:
The AWS Well-Architected Tool is designed for assessing architectures against best practices, but it does not specifically support importing CMDB data for analysis or generating migration recommendations directly. It focuses more on architectural reviews than on migration planning.
Migration Evaluator is a tool specifically designed to help organizations assess their current infrastructure and plan for migration to AWS. It allows for the import of CMDB data using a data import template, making it a targeted and cost-effective solution for generating a business case for migration.
Implementing resource matching rules and using the AWS Price List Bulk API to query CMDB data would require significant custom development and integration work. This approach is complex and may not yield the most straightforward or cost-effective insights compared to more dedicated tools.
AWS Application Discovery Service is primarily used for discovering and understanding existing on-premises environments, focusing on the collection of usage and configuration data. While it can aid in migration efforts, it is not designed specifically for analyzing CMDB data in a straightforward manner for creating a business case.
In my opinion, the answer is:
Use Migration Evaluator to perform an analysis. Use the data import template to upload the data from the CMDB export.
