Instance Store
  • An instance store provides temporary block-level storage for your instance.
  • This storage is located on disks that are physically attached to the host computer.
    • Very high IOPS because it is attached physically.
  • Instance store is ideal for temporary storage of information that changes frequently, 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.
  • The instance type determines the size of the instance store available and the type of hardware used for the instance store volumes.
  • Instance store volumes are included as part of the instance's usage cost.
  • You can specify instance store volumes for an instance only when you launch it.
  • You can't detach an instance store volume from one instance and attach it to a different instance.
    ​
  • The data in an instance store persists only during the lifetime of its associated instance.
  • If an instance reboots, data in the instance store persists.
    • However, data in the instance store is lost under any of the following circumstances:1
      • The underlying disk drive fails
      • The instance stops or hibernates or terminates
      ​
  • Do not rely on instance store for valuable, long-term data.
    • Instead, use more durable data storage, such as Amazon S3, Amazon EBS, or Amazon EFS.
