A company uses AWS Cloud Formation to deploy its infrastructure. The company recently retired an application. A cloud operations engineer initiates CloudFormation stack deletion, and the stack gets stuck in DELETE FAILED status.
A SysOps administrator discovers that the stack had deployed a security group. The security group is referenced by other security groups in the environment. The SysOps administrator needs to delete the stack without affecting other applications.
Which solution will meet these requirements m the MOST operationally efficient manner?
Retain the Security Group:
When deleting a CloudFormation stack, you can specify resources to be retained instead of deleted.
Steps:
Go to the AWS Management Console.
Navigate to CloudFormation and select the stack.
Choose to delete the stack.
In the deletion options, specify that the security group should be retained.
This will delete the stack but keep the security group, ensuring no impact on other applications.
