Which AWS tool provides a baseline inventory of on-premises workloads and estimates the projected cost to run those workloads in AWS?

Migration Evaluator (formerly TSO Logic) is a no-cost service that helps create a data-driven business case for AWS cloud migration. It provides a baseline inventory of on-premises workloads and estimates the projected cost to run those workloads in AWS, including right-sizing recommendations. AWS Compute Optimizer recommends optimal AWS resources for your workloads to reduce costs and improve performance, but it focuses on existing AWS resources, not on-premises. AWS Cost Explorer allows you to visualize, understand, and manage your AWS costs and usage over time, but it doesn't inventory on-premises workloads or estimate migration costs. AWS Systems Manager Agent (SSM Agent) is software installed on EC2 instances or on-premises servers and VMs that allows Systems Manager to update, manage, and configure them, not for migration cost evaluation.
