I feel there is a difference between

 

-          Is it possible ?

-          Is it a good approach for use case X ?

 

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.

+1. 

 

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
