Question #1405
A company is preparing to migrate its on-premises application to AWS and needs to identify server dependencies and collect configuration details. Which AWS service should the company use to facilitate this process?
AWS Migration Hub
AWS Config
AWS Application Discovery Service
AWS Server Migration Service (SMS)
Explanation
The correct answer is C. AWS Application Discovery Service (ADS) is specifically built to assist in migration planning by automatically discovering on-premises servers, mapping dependencies between applications, and collecting detailed configuration data (e.g., CPU, memory, disk usage, network connections). This information is critical for designing an effective migration strategy.
Why other options are incorrect:
- A. AWS Migration Hub aggregates migration statuses from multiple tools but does not perform discovery or data collection itself.
- B. AWS Config tracks AWS resource configurations post-migration but does not support on-premises discovery.
- D. AWS Server Migration Service (SMS) focuses on migrating VMs to AWS but does not handle dependency mapping or configuration analysis.
Key Point: ADS is the go-to service for pre-migration discovery and dependency analysis.
Answer
The correct answer is: C
