What is the primary tool used for pricing AWS services?

The AWS Pricing Calculator is specifically designed to estimate the costs of using various AWS services based on user-defined configurations. It provides a comprehensive interface that allows users to input their expected usage patterns and resource types, enabling them to forecast costs effectively before committing to services. The calculator clearly breaks down costs by resource, making it straightforward for users to generate detailed pricing estimates for their specific needs.

While the other options serve important roles in managing AWS costs, they do not primarily focus on pricing estimation. AWS Cost Explorer helps analyze past spending patterns and provides insights into usage trends, whereas AWS Budget Tracker monitors budgets and alerts users when spending exceeds set thresholds. The AWS Billing Dashboard offers an overview of billing information, including payments and current usage, but is not primarily a pricing tool. Thus, the AWS Pricing Calculator stands out as the main tool for current and prospective users to understand and estimate pricing for AWS services.
