The most recent "general purpose" instance families (C4, G3, M4, P2, R4) don't offer ephemeral storage anymore. My guess is that AWS will only offer ephemeral storage for a few selected instance families in future. So you have to decide: older instance types (which will become more expensive as they usually don't benefit from new price reductions) or no ephemeral storage
