AWS AutoScaling LaunchConfiguration

AWS AutoScaling LaunchConfiguration

The AWS::AutoScaling::LaunchConfiguration resource specifies the launch configuration that can be used by an Auto Scaling group to configure Amazon EC2 instances.When you update the launch configuration for an Auto Scaling group, CloudFormation deletes that resource and creates a new launch configuration with the updated properties and a new name. Existing instances are not affected. To update existing instances when you update the AWS::AutoScaling::LaunchConfiguration resource, you can specify an UpdatePolicy attribute for the group.
