OpenNebula and Eucalyptus (as well as CloudStack) are alternative
solutions in the open source IaaS Compute space. Note that OpenStack
provides more than just IaaS Compute feature (Nova), it also addresses
object storage (Swift), or network (Quantum)...

OpenStack is being used to power public clouds (HP, Rackspace, AT&T,
Internap, Korea Telecom, SDSC...). Those are unfortunately notoriously
shy at sharing size numbers :)

OpenStack is being used in a number of research clouds, including NeCTAR
(Australia's national research cloud). There is huge interest around
bridging the gap there, with companies like Nimbis or Bull being involved.

Hopefully people with more information than I have will comment on this
thread.
