What feature of AWS allows you to control costs based on usage?

AWS Budgets is designed to help you manage and control your spending on AWS services. It allows users to set custom cost and usage budgets that monitor their spending against the defined thresholds. By using AWS Budgets, you can receive alerts via email or SMS if your usage exceeds the budgeted amount, enabling proactive financial management and better decision-making to keep costs in check.

This feature empowers organizations to keep a close eye on their cloud expenditures and helps in making more informed choices regarding resource utilization. By understanding and acting upon this information, businesses can effectively manage their costs and avoid unexpected charges.

While options like Amazon Cost Explorer provide insights into spending habits and resource usage over time, and AWS Savings Plans help with cost reduction by committing to use certain services over a period, these do not inherently offer a mechanism for actively managing costs based on real-time usage in the same way that AWS Budgets does. AWS Trusted Advisor provides best practices guidance but does not focus specifically on cost control features.
