[CentOS] managing a rack full of centos servers

I'm managing two data centers and some instances on rackspace cloud servers.
 Currently running Cobbler+Puppet+Mcollective.  So far it's been great for a
team of one, myself.

At the moment I'm looking into either using Aeolus or Openstack to bridge
the gap of my data centers and the public cloud still keeping
Puppet+Mcollective in the mix and seeing if Cobbler is still needed.

Anyone out there tried both Aeolus *and* Openstack yet?  I'm looking
to supplement my research on these two private/public cloud tools. =)
