No ARM on EC2, but you can mix and match clouds as you will. Providers
are now just config options so you can easily add and change the
environments and resources that you leverage anytime you want.

There's really a world of possibilities available, we just have to
identify the correct level of abstraction the Fedora community is
looking for.

Absolutely, repositories and packages can be added on the fly, and we
can incorporate any image already pushed to the cloud as well as build
new ones for our purposes.

Even what I demoed in the screencast (just the tip of the iceburg
concerning Deltacloud's capabilities) can be automated such that new
cloud instances w/ any stack we want can be provisioned on demand
anywhere we want.

Really the workflow at this point is the only thing vague to me, once
that's down I'm sure it can be implemented.

Perhaps people can send their thoughts or we can discuss it at the next
cloud sig meeting? (Wednesdays at 10AM EST on #fedora-meeting-1 for
those that are interested)

I've said it before and I'll say it again, the cloud is _not_ the be all
end all. :-) Its a great tool, and brings a powerful computational
resource to the table, but it's never going to completely mitigate local
infrastructure.

I think hybrid technologies is the future, being able to leverage cloud
resources in addition to and along side of local ones seemlessly in an
open manner will really enable us to do some really cool things. I
believe Fedora can make great headway and lead on this front, we just
have to find what works for people and do it! :-)
