Which Two Tools Calculate AWS Compute TCO?

Why the Answer Is Correct

The AWS Pricing Calculator lets you model the exact AWS services, configurations, and billing terms for your target architecture and produces an itemized cost estimate, which is the direct-cost half of a TCO calculation. Migration Evaluator complements this by analyzing your current server-based estate and projecting AWS costs (including right-sizing recommendations) so you can compare on-premises spend against AWS. Together these two tools cover both sides of a TCO analysis, which is exactly what the question's combination requirement demands. As HimoMemo noted, Migration Evaluator matters for "right-sizing, which is essential for accurate cost estimation."

Why the Other Options Are Wrong

AWS Support Center (C) is a support-case portal and has no cost-modeling function, so it cannot produce a TCO figure. AWS Application Discovery Service (D) discovers and maps on-premises servers, applications, and their relationships, feeding data into migration planning tools but stopping short of any cost calculation. AWS Database Migration Service (E) actually moves database data into AWS and is an execution tool, not an estimation tool, so it is irrelevant to calculating ownership costs. ShaiTay and d00b229 both independently confirmed the A and B pairing.

Community Comment Notes

All three commenters converged on the same combination, with HimoMemo explaining that the Pricing Calculator handles direct costs while Migration Evaluator adds right-sizing context. ShaiTay and d00b229 each simply restated "A. AWS Pricing Calculator B. Migration Evaluator" without further justification. The unanimity aligns with AWS's own documentation, though learners should still verify the reasoning rather than relying on vote counts alone.
