Thanks Adrian!

We should probably make it clear for those who can't be at Summit that 
this is not intended to be a record of the design summit discussions. 
I'd describe this as a snapshot of Adrian's evolving vision for Heat, 
taken after the design summit sessions. In particular, I think it 
reflects a couple of misconceptions about the current architecture of 
Heat, and it also contains some stuff that hasn't been discussed at all 
at Summit (e.g. the CEP part... btw my initial reaction to this is that 
it should probably talk to Ceilometer rather than the Autoscaling service).

That said, there certainly *is* consensus that we want to evolve Heat 
toward being able to orchestrate whole applications rather than just 
services. We'll be doing further work throughout the week and 
subsequently on the mailing list to refine some of these architectural 
ideas, and we're looking forward to working with Adrian and his team at 
Rackspace to make it happen :)

For the benefit of those who are not attending, or who were not in these sessions, I created this Wiki page to express what I think is an early consensus on where we could take things. Let's tweak this if it's not a good direction.
