Launch Configuration with EBS-backed AMI and defined block device mappings

This template creates a launch configuration that can be used by an Auto Scaling group to configure Amazon EC2 instances. It specifies an EBS-backed AMI and defines two block device mappings: a 30 gigabyte EBS root volume mapped to /dev/sda1 and a 100 gigabyte EBS volume mapped to /dev/sdm. The /dev/sdm volume uses the default EBS volume type based on the region and is not deleted when terminating the instance it is attached to.
