At Netflix we use Cassandra and store all data on local instance storage. We don't use EBS for databases.
It's one of those "huh, never ever thought of it from that angle" sort of ideas. The very idea of putting your absolutely valuable data on ephemeral storage and just duplicating it.
Thanks for that.
