Which AWS service helps users plan and track their server and application inventory migration data to AWS?

Explanations:

Amazon CloudWatch is a monitoring service for AWS cloud resources and applications. It provides data and insights about resource utilization, operational performance, and overall system health but does not focus on planning and tracking migration data.

AWS DataSync is a data transfer service that automates moving data between on-premises storage and AWS storage services. While it helps in transferring data, it does not provide a comprehensive solution for planning and tracking the entire migration process.

AWS Migration Hub provides a central location to track the progress of application migrations across multiple AWS and partner solutions. It helps users plan and monitor their migration projects effectively, making it the correct choice for tracking server and application inventory migration data to AWS.

AWS Application Migration Service (formerly known as AWS Server Migration Service) simplifies the process of migrating applications to AWS. However, it focuses on the actual migration of workloads rather than the planning and tracking aspect of migration data, making it less suitable for the specified task.
