Which AWS service provides alerts and tracking to help monitor and control overall operating costs for an AWS environment?

AWS Budgets allows you to set custom budgets that alert you when your costs or usage exceed (or are forecasted to exceed) your budgeted amount. This proactive monitoring helps you stay within your spending limits and control overall operating costs. Amazon EventBridge is a serverless event bus that connects application data from your own apps, SaaS, and AWS services, not primarily for cost monitoring. Compute Savings Plans offer discounted pricing in exchange for a commitment to a consistent amount of compute usage, but they don't provide alerts or tracking for overall costs. Migration Evaluator helps assess the cost of migrating on-premises workloads to AWS, rather than monitoring ongoing operational costs.
