Deleting Your AWS CloudFormation Live Smooth Streaming Stack
When your live event is over, delete the stack that you created for Live Smooth Streaming. This deletes the AWS resources that were created for your live event, and stops the AWS charges for those resources.
To delete an AWS CloudFormation stack for live streaming
Sign in to the AWS Management Console and open the AWS CloudFormation console at https://console.aws.amazon.com/cloudformation/.
Check the checkbox for the stack, and click Delete Stack.
Click Yes, Delete to confirm.
To track the progress of the stack deletion, check the checkbox for the stack, and click the Events tab in the bottom frame.
