Christian Karnath commented on DTACLOUD-443:
--------------------------------------------
Marios: Thank you for your feedback. While considering options please keep in
mind that the regions for compute and object-storage must not be the same. For
example HP uses different regions for compute and object storage. I think it
would make sense to flag every realm with a list of supported service types.
Due to this, when requesting for example all instances, you have to loop
through all realms and merge the subsets. Another point is, that for HP Cloud
different authentication servers have to be queried to get a list of _all_
regions.

> Hey Marios,
> HPCloud provides three different compute clouds (availability zones) at the
> moment. How can I specify which compute cloud is used with the openstack
> driver, because the API credentials and the URL endpoint of the identity
> service (keystone) are the same. Connecting and authenticating directly to
> the nova-api of a specific compute cloud is not possible, because HPCloud is
> using keystone as a centralized identity management solution.
> I guess when authentication against the identity service all three compute
> clouds are returned, but only the first cloud is manageable with deltacloud?
> Would it make sense to re-implement /api/realms for this case? The current
> /api/realms implementation could be retained for users who are connection
> directly to a specific nova api endpoint (i. e. an openstack environments
> without keystone).
> Best
> Christian
