All,
We've been working on a Virtual Organization (VO) capability to allow
federated OpenStacks. So far, we've concentrated on just federated data
access, having modified Keystone and Swift on both the server and client
sides. The are a number of further distributed/federated capabilities
that one can imagine, e.g., authorizing one Keystone to instantiate VM
through a remote Nova.
Obviously, any type of resource federation requires security federation.
In the general case, this requires federated identity management, as
David Chadwick at Kent has been working on. This type of federation is
somewhat different than just sharing a Keystone or Glance among multiple
instances, but is arguably more general.
I would really like the OS community to achieve some rough consensus
about what kinds of federation models are desirable and how to build them.

Multi-site varies hugely depending on whether the aim is sharing the
work or recovery scenarios.
Defining a good model for multi-site, resilient deployments and
multi-site, maximum throughput/utilisation would be very interesting.

We're going to be running a bunch of parallel deployments of openstack
for the purpose of experimentation in system design. it would be nice to
be able to share glance and keystone between instances.

Hi,
We're looking at setting up a geographically distributed OpenStack
installation, and we're considering either cells or regions. We'd
like to share a single Glance install between our regions (or
cells), so the same images can be spawned anywhere. From here:
http://docs.openstack.org/trunk/openstack-ops/content/segregate_cloud.html
it's not clear whether that's possible. Can anyone shed some light
on this? Is it possible in regions OR cells (or both)? Is there a
better solution that I'm not thinking of?
thanks,
JP
