i am planning to install openstack with 2 regions.Already added one region with shared horizon and keystone now planning to add one more.But my concern is how can i bring in DC level HA for keystone and horizon;even if DC1 goes down horizon and keystone should work from DC2.Any standard way of achieving this.Each DC has its own HA Proxy for all services. Thanks for any help -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack/attachments/20151229/9b717870/attachment.html>
