A template for the root volume for 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
Rather, it is a standalone region with the same APIs and services as available in other AWS regions, but a user must create a separate AWS account for AWS China and cannot use the AWS Global account.

Instance-store volumes are temporary storage, which survive rebooting an EC2 instance, but when the instance is stopped or terminated (e.g., by an API call, or due to a failure), this store is lost. The Amazon Elastic Block Store (EBS) provides raw block devices that can be attached to Amazon EC2 instances. These block devices can then be used ...
