Answer: AWS Application Discovery Service

## Explanation **AWS Application Discovery Service** is specifically designed to help enterprises plan migration projects by gathering information about their on-premises data centers. Here's how it works: ### Key Features: - **Server Discovery**: Automatically identifies servers and their configurations - **Application Dependency Mapping**: Discovers how applications interact with each other - **Performance Data Collection**: Gathers resource utilization metrics - **Database Discovery**: Identifies databases and their characteristics ### Why Other Options Are Incorrect: - **AWS Application Migration Service**: This service actually performs the migration of applications, but doesn't focus on discovery and assessment - **AWS Database Migration Service (AWS DMS)**: This service migrates databases but doesn't provide the initial assessment capabilities - **AWS Mainframe Modernization**: This is for modernizing mainframe applications, not for discovery and assessment ### Use Case: Before migrating to AWS, companies use Application Discovery Service to understand their current infrastructure, plan migration strategies, estimate costs, and identify dependencies between applications.
