But, unless I'm mistaken, there is only a single call to the auth
server on the first request. If we go with a Swift model (which is
similar to the proposed solution from Vish and Andy, but not quite the
same), the auth server returns the storage-management-url after
authenticating the user/key combination. Requests after the initial
request simply use the storage management URL, passing in the token
returned from the auth service. You could issue dozens of requests
after the initial auth request, and you wouldn't be re-requesting
anything from the auth server each time.
I agree it would be nice to be able to specify "spin me up 10 servers"
in the OpenStack compute API, but that is a bit tangential to the
specifics of the auth service here, AFAICT.
