</div><div><br></div><div>On the one hand, it says different regions should have no interactions among them. On the other hand, it says keystone should be shared across regions. I can see that sharing credentials is useful, but replicating things like tokens across region seems to be a hassle to deal with - I don't want to replicate the tokens that are specific to regions via WAN.. </div>
<div><br></div><div>Second, I am confused about Horizon's multi-region support. There are two ways of informing a horizon instance about multiple regions. One way is to configure the AVAILABLE_REGIONS variable in local_settings.py, where I can put keystone endpoints associated to different regions. Then something would show up in the top right corner of horizon, that I can switch to a different region, log in, and it works. The second way is to configure the endpoints of another region in the keystone instance local to horizon. Then, a drop down list would show up on the left side of the page, right beneath the list of projects. This however doesn't work, since the openstack_auth package seems to be performing a simple redirect assuming the same token would work across regions (my two regions have completely separate keystone deployments.)</div>
