Correct answer: AWS Application Discovery Service.
Why this is the answer
AWS Application Discovery Service helps you plan migration projects by automatically identifying applications, servers, and their dependencies in your on-premises data centers. It collects configuration, usage, and performance data, which is crucial for assessing migration readiness and optimizing target AWS environments. AWS DataSync is for transferring large amounts of data online between on-premises storage and AWS. AWS Storage Gateway connects on-premises applications to cloud storage. AWS Database Migration Service (DMS) helps migrate databases to AWS quickly and securely, but it doesn't discover the entire on-premises environment.
