AWS 雲服務各組件之間的關係

一、Voulme、Sanpshot、AMI、EC2

An AMI includes the following:

• One or more EBS snapshots, or, for instance-store-backed AMIs, a template for the root volume of the instance (for example, an operating system, an application server, and applications).
• Launch permissions that control which AWS accounts can use the AMI to launch instances.
• A block device mapping that specifies the volumes to attach to the instance when it's launched.
