The typical conundrum here is making "the easy things easy, and the hard
things possible". It doesn't have to be a choice between a) providing a
rich API with access to all the features of each individual compute
paradigm, and b) providing a simple API that allows users to request a
compute resource of any type that's available in the public/private
cloud they're interacting with. OpenStack can have both.
The simple lowest common denominator interface would be very limited
(both by necessity and by design), but easy to understand and get
started on, making some smart assumptions on common usage patterns. The
richer APIs are there for users who need more power and flexibility, and
are ready to go beyond the easy on-ramp.
Again, nothing new here, it seems to be the direction we're already
heading. I'm just articulating why.
