EC2 Instance Store

Whilst EB2 network drives offer good but limited performance, there is another type of volume store called EC2 Instance Store.

An EC2 instance store is a high performance hardware disk which offers better I/O performance than an EB2 volume.
However, be aware that an EC2 Instance Store will lose all their information once they are stopped and are therefore ephemeral.

The use case for an EC2 Instance Store is for caching, storage of temporary information, scratch data etc, essentially any temporary information you can afford to lose.

The backup and replication of EC2 Instance Stores is the responsibility of the AWS user and EC2 Instance Stores run the risk of data loss in the event of hardware failure.
