Instance storage:极高的IO，临时存储。
EC2 local instance store volumes are ideal for temporary storage of information that is continually changing, such as buffers, caches, scratch data, and other temporary content, or for data that is replicated across a fleet of instances, such as a load-balanced pool of web servers. EC2 instance storage is well-suited for this purpose.

Organizations are using AWS Storage Gateway to support a number of use cases. These use cases include corporate file sharing, enabling existing on-premises backup applications to store primary backups on Amazon S3, disaster recovery, and mirroring data to cloud-based compute resources and then later archiving it to Amazon Glacier.
Snowball:TB,PB级数据上云。
Snowball is ideal for transferring anywhere from terabytes to many petabytes of data in and out of the AWS Cloud securely.Common use cases include cloud migration, disaster recovery, data center decommission, and content distribution.
