Deleting an AWS CloudFormation Stack for Live Streaming
When your live event is over, delete the stack that you created for live streaming. This deletes the AWS resources that were created for your live-streaming event and stops the on-demand charges for the resources.
To delete an AWS CloudFormation stack for live streaming
Open the AWS CloudFormation console at https://console.aws.amazon.com/cloudformation/.
In the upper right corner, choose the region in which you created your stack.
Select the stack, and then choose Delete Stack.
Choose Yes, Delete to confirm.
To track the progress of the stack deletion, select the stack, and then choose the Events tab.
