CloudFormation Stack Rollback Behavior

When you create a stack in AWS CloudFormation and one resource fails to create, the entire stack creation is rolled back by default. That means:

  • All previously created resources will be automatically deleted.

  • The final result is: no resources remain, and the stack status becomes ROLLBACK_COMPLETE.

  • Check the status of a stack:

aws cloudformation describe-stacks --stack-name stack-id
