AWS Application Discovery Service for On-Premises Migration Planning

SAA-C03 By islever Editorial Last updated

Design secure access to AWS resources.

Short answer

B Use AWS Application Discovery Service to collect usage and configuration data about on-premises servers for migration planning.

Question

A company runs multiple workloads in its on-premises data center. The company's data center cannot scale fast enough to meet the company's expanding business needs. The company wants to collect usage and configuration data about the on-premises servers and workloads to plan a migration to AWS. Which solution will meet these requirements?
  1. Set the home AWS Region in AWS Migration Hub. Use AWS Systems Manager to collect data about the on-premises servers.
  2. Set the home AWS Region in AWS Migration Hub. Use AWS Application Discovery Service to collect data about the on-premises servers. Correct Answer
  3. Use the AWS Schema Conversion Tool (AWS SCT) to create the relevant templates. Use AWS Trusted Advisor to collect data about the on-premises servers.
  4. Use the AWS Schema Conversion Tool (AWS SCT) to create the relevant templates. Use AWS Database Migration Service (AWS DMS) to collect data about the on-premises servers.

Key Takeaways

The key insight is distinguishing between general management tools like Systems Manager and specialized discovery tools, as only Application Discovery Service provides the necessary infrastructure data for migration assessment.

This question tests the correct AWS tool for collecting on-premises server usage and configuration data during migration planning. The page establishes that AWS Application Discovery Service is the dedicated solution for this specific requirement.

Common mistake: Learners often incorrectly choose AWS Systems Manager (Option A), confusing general remote management capabilities with the specific infrastructure discovery features required for migration planning.

Expert Analysis

Why the Answer Is Correct

AWS Application Discovery Service is specifically designed to help plan migrations by collecting detailed usage and configuration data about on-premises servers and databases. This data is critical for determining appropriate instance types and storage requirements in AWS. When integrated with AWS Migration Hub, it provides a centralized view of the migration journey, making Option B the correct choice.

Why the Other Options Are Wrong

Option A suggests using AWS Systems Manager, which manages instances but does not automatically collect the deep infrastructure dependency and performance history data needed for migration sizing. Options C and D are incorrect because AWS Schema Conversion Tool (SCT) is for database schema conversion, not server discovery, and AWS Database Migration Service (DMS) is for moving data, not gathering server metrics.

Community Comment Notes

The community consensus strongly supports Option B. As Scheldon noted, "AWS Application Discovery Service helps you plan your migration... by collecting usage and configuration data." This aligns perfectly with the official AWS documentation defining the service's primary purpose.

Exam Strategy

Focus on the specific action verb in the question: 'collect usage and configuration data'. If the goal is migration planning involving server discovery, immediately look for Application Discovery Service rather than general management or database-specific tools.

Frequently Asked Questions

Why is AWS Systems Manager incorrect here?

Systems Manager manages running instances but lacks the automatic discovery of dependencies and historical usage metrics required for migration assessment.

What is the role of AWS Migration Hub in this scenario?

Migration Hub acts as a central dashboard to track progress, while Application Discovery Service performs the actual data collection task described in the question.
