Set up Budgets and Budget Alarms

This is a quick reference guide on setting up budgets and budget alarms on AWS.

Step 1: Set up budget costs Setting up budget costs is an important part of managing your AWS costs. To set up a budget, navigate to the AWS Management Console and select the "Billing and Cost Management" service.

From there, select "Budgets" from the left-hand menu and click on "Create a budget". In the budget creation screen, you'll need to set the budget type (either cost or usage), the budget amount, and the budget period.

You can also set up budget filters to include or exclude specific AWS services, regions, or tags. This can be useful if you want to create separate budgets for different parts of your AWS infrastructure.

Once you've set up your budget, click "Create" to create the budget.

Step 2: Set up budget alarms Budget alarms are notifications that are triggered when your AWS costs exceed a certain threshold. This can be useful for keeping track of your costs and preventing unexpected charges.

To set up a budget alarm, navigate to the budget you created in Step 3 and click on the "Create alarm" button. In the alarm creation screen, you'll need to set the alarm name, the threshold amount, and the notification options.

You can also set up alarm actions, which are actions that are triggered when the alarm is triggered. For example, you can set up an action to automatically stop EC2 instances when costs exceed a certain threshold.

Once you've set up your alarm, click "Create" to create the alarm.
