AWS Budget with CloudFormation

Creating an AWS budget is a crucial step when starting a new AWS account or project in the cloud. It helps to ensure that your AWS spending aligns with your current business goals and prevents unexpected costs from affecting your budget.

While many tutorials focus on manual budget creation, there's an even better solution for those who prioritize automation. By utilizing an AWS budget, you can set custom cost thresholds for your AWS accounts, and receive notifications when actual costs exceed the budgeted amount. This allows for efficient cost management and ensures that your AWS usage stays within your desired budget
