AWS Budgets has enhanced the console experience by adding a split-view panel that allows you to view budget details without leaving the budgets overview page. AWS Budgets helps you control AWS cost and usage by allowing you to set custom budgets that alert you when your cloud spend exceeds (or is forecasted to exceed) your budgeted amount. You can also use AWS Budgets to set Savings Plans and Reservation alerts and receive notifications when your utilization or coverage targets drop below your desired thresholds. AWS Budgets is generally available in all public AWS Regions.
