A company has moved all its infrastructure to the AWS Cloud.

AWS Budgetsallows users to set custom cost and usage budgets and receive notifications when they exceed their thresholds. It provides detailed reports on cost and usage data for the past and current months, enabling the finance team to track and analyze spending.

AWS Budgets can automatically generate cost and usage reports, which can help the finance team plan ahead for each quarter based on historical data.

Why other options are not suitable:

A. Amazon Detective: A security service for analyzing and investigating AWS account activity for security purposes, not cost tracking.

B. AWS Pricing Calculator: A tool to estimate costs based on expected usage, not for tracking actual past usage.

D. AWS Savings Plans: An offering to save costs on AWS usage; it does not provide cost tracking or reporting features.
