AWS Service for Cost Estimation Before Migration

CLF-C02 By islever Editorial Last updated

Compare AWS pricing models.

Short answer

D Use the AWS Pricing Calculator to estimate the cost of your AWS architecture solution before migration.

Question

A company wants to estimate the cost for its AWS architecture solution before migration. Which AWS service or feature will meet this requirement?
  1. Amazon Detective
  2. AWS Budgets
  3. AWS Resource Explorer
  4. AWS Pricing Calculator Correct Answer

Key Takeaways

This question tests knowledge of AWS cost management tools, specifically distinguishing between estimation (Pricing Calculator) and monitoring/budgeting (Budgets). The common trap is selecting Budgets, which is for tracking actual or set budgets after setup, not for initial architectural estimation.

The AWS Pricing Calculator is the correct service to estimate costs for an AWS architecture solution before migration. This page explains why it is the only tool designed for pre-migration cost estimation among the options.

Common mistake: Candidates often incorrectly select AWS Budgets because it relates to costs. However, Budgets are used to set limits and track usage against those limits, whereas the Pricing Calculator is explicitly for estimating costs based on resource configurations before deployment.

Expert Analysis

Why the Answer Is Correct

The AWS Pricing Calculator is a web-based tool that allows users to estimate the cost of using AWS services. It enables you to input specific details about your planned architecture, such as instance types, storage volumes, and data transfer rates, to generate a detailed cost estimate. This makes it the ideal tool for a company wanting to estimate costs before migrating its architecture.

Why the Other Options Are Wrong

Amazon Detective is a security service that helps analyze, investigate, and quickly identify the root cause of potential security issues or suspicious activities; it has no function in cost estimation. AWS Budgets allows you to set custom budgets that help you manage costs and usage, but it requires existing resources to track; it does not provide pre-deployment estimates for new architectures. AWS Resource Explorer is a service for discovering and searching for AWS resources across Regions and accounts, unrelated to cost planning.

Community Comment Notes

The community consensus strongly supports option D. As user Kilobay1 noted, "AWS Pricing Calculator is a web-based tool that helps you estimate the cost..." confirming its purpose. Multiple other users simply confirmed "D is correct," indicating high confidence in this answer within the exam preparation community.

Exam Strategy

Always distinguish between tools used for 'estimating' future costs versus 'tracking' current costs. For pre-migration or design-phase questions, look for the Pricing Calculator. For post-migration monitoring or alerting, consider Budgets or Cost Explorer.

Frequently Asked Questions

Why is AWS Budgets incorrect for pre-migration estimation?

AWS Budgets tracks actual or projected spending on existing resources. It cannot estimate costs for an architecture that hasn't been deployed yet.

Can I use Cost Explorer for pre-migration estimates?

No, Cost Explorer analyzes historical usage data. Since the architecture is not yet migrated, there is no historical data to analyze.
