Open Stack

For reference, here's a detailed description of the possible ways to
segregate OpenStack Compute:

http://docs.openstack.org/trunk/openstack-ops/content/scaling.html#segregate_cloud

My initial thought is to base your decision on how you want your segregated
cloud to appear. For example: do you want each segregated area to have its
own quota? If so, look into Cells or Regions. If not, then look into AZs or
Host Aggregates.

As another example, with Regions, users will have to explicitly log in to a
different region through the Dashboard. The different regions will not
appear as one large Compute service. I'm not sure how Cells work in this
regard. AZs and HAs appear under the same Dashboard session.

I'm not familiar enough with Neutron to know how a certain choice will
affect the network service. I do know that separate Compute environments
can share the same Identity and Image services, though.

I hope that helps,
Joe
