+2 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.

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. -nld On Wed, May 15, 2013 at 1:46 PM, John Paul Walters <jwalters at isi.edu <mailto:jwalters at isi.edu> > wrote: 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 _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack at lists.launchpad.net <mailto:openstack at lists.launchpad.net> Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp -------------- next part -------------- An HTML attachment was scrubbed...
