What AWS service or tool will meet these requirements?

Explanations:

AWS Compute Optimizer helps optimize instance types based on utilization but does not provide a baseline of on-premises workloads or cost projections for migration to AWS.

AWS Cost Explorer is used for analyzing AWS costs and usage over time but does not assess on-premises workloads or provide a migration cost projection.

AWS Systems Manager Agent (SSM Agent) is used for managing and automating tasks in AWS resources and on-premises servers, but it does not provide workload baselines or cost projections for migration.

Migration Evaluator (formerly TSO Logic) is designed to assess on-premises workloads and provide insights on their costs, helping to project the expenses of running these workloads in AWS. It delivers the required baseline and cost estimation for migrating to the cloud.
