An Amazon Machine Image (AMI) provides the information required to launch an instance. You can
use an AMI to launch identical instances from a standard template. This is also known as a
Golden Image (though no such feature exists in AWS with this name). An AMI is created from an
EBS snapshot and also includes launch permissions and a block device mapping.
Amazon Block Templates and Amazon Machine Images do not exist.
An Amazon EBS Mount Point is not an AWS feature. You do mount EBS volumes however this is within
the operating system. Block device mappings are used in AMIs to specify how to mount the EBS
volume.
