In AWS migration, what is the role of AWS Migration Hub?

• A. Prospects cloud ROI by forecasting migration costs.
• B. Centralizes discovery, planning, and tracking of migration progress across multiple tools and applications.
• C. Hosts the migration job queue and executes transfer tasks.
• D. Manages security policies for on-prem data.

Answer: (B)

AWS Migration Hub provides a centralized view to discover, plan, and track migration progress across multiple tools and applications. It collects discovery data from tools like Application Discovery Service and presents a single console that shows what needs to be moved, dependencies, and how far each migration has progressed, regardless of which migration tool is used. It doesn’t forecast cloud ROI or migration costs, and it doesn’t host a migration job queue or enforce on‑prem security policies—the execution and policy enforcement are handled by other services. So the best fit is its role as the unified central place for discovery, planning, and progress tracking across the migration stack.
