An Azure relational database service.
@Kyle Jung Welcome to the Microsoft Q&A forum, Thanks for posting your question.
You can set up a block when the usage limit is exceeded, you can create an alert rule in Azure Monitor email alerts triggered to trigger when the usage limit is exceeded, and then configure an action to block further usage. You can also set up an email notification to be sent when the alert is triggered. however, If you want to avoid being charged for additional usage, you can stop the resource after usage. Stopping a resource will temporarily halt the resource and you will not be charged for the stopped resource.
Please let me know if you have any additional questions.
Regards
Geetha
