This is the biggest un-addressed problem, IMO. Getting more scientific computing done in the cloud is where we are inevitably trending, but no-one yet has a good answer for completely ad-hoc, low value experimentation and skill building in cloud. I see universities needing to maintain clusters to allow PhDs and postdocs to develop their computing skills for a good while yet.
