A company will run experimental workloads in AWS with a fixed budget. The CFO needs spending accountability per department and wants to receive a notification when spending reaches 60% of the budget. Which solution meets these requirements?

The correct solution involves two key components: cost allocation tags and AWS Budgets. Cost allocation tags are essential for tracking spending by department, as they allow you to categorize resources and their associated costs. AWS Budgets is the service designed to set custom budgets and receive alerts when spending exceeds predefined thresholds, such as 60% of the budget. Incorrect options: AWS Cost Explorer forecasts can predict future spending but do not directly attribute costs to owners or provide budget alerts. AWS Cost Anomaly Detection identifies unusual spending patterns, not budget thresholds. AWS Trusted Advisor focuses on optimizing costs, security, and performance, but its API doesn't directly create budget-based spending alerts. While AWS Budgets is correctly identified, relying on AWS Cost Explorer forecasts to determine resource owners is inefficient and not its primary purpose for cost allocation. Cost allocation tags are the direct and intended method for this.
