Which AWS feature could assist in setting budget alerts for S3 expenses?

1. AWS CloudTrail

2. AWS Budgets

3. AWS Auto Scaling

4. AWS Config

The correct answer is: AWS Budgets

AWS Budgets is the feature specifically designed to help you set budget alerts for your expenses, including those related to S3. It allows you to define budget constraints and set thresholds for your spending, providing proactive alerts as you approach or exceed those limits. This is particularly useful for managing costs in a cloud environment where usage can fluctuate, as it empowers users to maintain tighter control over their budget and adjust their usage accordingly. In contrast, the other options serve different purposes: AWS CloudTrail focuses on logging API calls to track changes and activities in your AWS account, which is not related to budgeting expenses. AWS Auto Scaling assists in dynamically adjusting compute capacity to meet application demand but does not involve cost monitoring or alerting capabilities. Meanwhile, AWS Config is centered around resource configuration tracking and compliance auditing, not budget management. These features are essential for managing cloud resources, but they do not directly address cost tracking like AWS Budgets does.
