Amazon EC2 Auto Scaling now allows you to view deleted Auto Scaling groups in the scaling history. Previously if you deleted an Auto Scaling group, you needed to either maintain a record of scaling activities for deleted Auto Scaling groups or ask AWS support team to retrieve the scaling activities for you. Now, you can specify one additional parameter in a describe call to get a description of the scaling history for deleted Auto Scaling groups. This makes it easier to keep a record of scaling activities after an application has been shut down.
