Which AWS service gives a single, central place to monitor the progress and status of application migrations?

AWS Migration Hub provides a single location to track the progress of application migrations across multiple AWS and partner migration tools. It centralizes migration status, allowing you to monitor the entire migration portfolio from one dashboard. AWS Application Discovery Service helps plan migrations by identifying on-premises applications and their dependencies, but doesn't track migration progress. AWS Application Migration Service (MGN) is a specific migration tool for rehosting applications, not a central monitoring service for all migrations. AWS Service Catalog allows organizations to create and manage catalogs of IT services approved for use on AWS, which is unrelated to migration tracking.
