A company needs to track monthly cost and usage for all Amazon EC2 instances in a particular AWS environment. Which AWS tool or service will provide that reporting?

AWS Budgets allows you to set custom budgets to track your cost and usage, and it can alert you when your costs or usage exceed (or are forecasted to exceed) your budgeted amounts. This makes it ideal for monitoring monthly spending on specific resources like Amazon EC2 instances. AWS Cost Anomaly Detection focuses on identifying unusual spending patterns rather than providing routine cost and usage reporting. AWS Compute Optimizer recommends optimal AWS resources for your workloads to reduce costs and improve performance, but it doesn't provide cost tracking. AWS Trusted Advisor offers recommendations on cost optimization, security, performance, and fault tolerance, but it's not a primary tool for ongoing cost and usage tracking.
