AWS summary of EC2 storage types

For my own sanity, as I always seem to struggle with this.

Elastic block store (EBS)

  • Can be attached to any EC2 instance in the same availability zone.
  • Recommended for long term persistence.
  • Can attach multiple EBS volumes to a single EC2 instance.
  • Survives reboot, stop/start and terminate (but only if not the root EBS volume).

Instance storage (ephemeral)

  • Storage attached directly to the EC2 instance (fast).
  • Recommended for short term/easily recreated data.
  • Will not survive stop/start/terminate, but will survive EC2 instance reboot.
  • Only available for select EC2 instance types (not an option for t1/t2 instance types).
