It is, technically, the same kind of snapshot as above, but it has also been registered with the EC2 service as an AMI, usable to launch new EC2 instances. An AMI image is a backup of an entire EC2 instance. AMIs hold the data that is needed in order to launch a new EC2 instance and are preferred for keeping a golden image that can support the automated provisioning of the same baseline instance.
