Purge deleted Stacks

Question

We have a workload that uses a CloudFormation Stack to create Amazon Connect Quick Connects.  The Stack has a fixed name: "AddressBook".  When the workload starts (about once per week), any existing AddressBook stack is deleted and a new AddressBook Stack created from a fresh template.  That all works good but we now have many instances of the AddressBook Stack with a DELETE_COMPLETE Status.  It seems a waste of resources to leave these deleted Stacks lying around.  How do you get rid of them, or am I worrying unnecessarily?

Answer

As long as the resources from the Cloudformation are all removed and not being [retained](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html) then those Delete_Completes are just record entries of past templates. They don't have any cost nor take up any service limit of your account.
