Which AWS service or tool can the company use to obtain this information?

Explanations:

The AWS Pricing Calculator allows users to estimate the cost of running applications on AWS by providing detailed pricing for different AWS services and configurations.

AWS Budgets is used to set budgets and track costs, but it does not provide a forecasting tool to estimate costs for running applications on AWS.

AWS Trusted Advisor provides real-time guidance to help users provision their resources following AWS best practices, but it does not focus on cost estimation.

Cost Explorer helps users visualize and manage their AWS spending over time, but it is not specifically designed for estimating future costs of running an application.
