We have created a wiki page with our initial thoughts: https://wiki.openstack.org/wiki/DisasterRecovery We encourage others to contribute to this wiki. What wasn't clear to me on first read is what the intended scope is. Exactly what is being failed over? An entire multi-tenant data-center? Specific tenants? Or specific enumerated sets of VMs for one tenant? The exact set could be from a single VM (with its associated resources: images, volumes, etc) to a set of entities associated with a user. The data-center itself (including its metadata and configuration) is consider the equivalent of the hardware - in case of disaster, you recover what is running, not the infrastructure. Thanks for pointing out the scope should be emphasized at the top... Regards, __ Ronen I.
