"Among the missing capabilitied was integration with Rackspace's
own internal systems for billing. As well, the original Nova code
lacked some abilities that Rackspace needed to resize a server up
or down. Toman stressed that Rackspace was looking for feature
parity from OpenStack with its existing cloud server solutions,
which is something that now, at long last, has been achieved.
Looking beyond just feature parity, using OpenStack will provide
operational benefits and features that go beyond what Rackspace
already is delivering. Toman noted that as part of the transition
to OpenStack, they are using the OpenStack Quantum networking
project as well. With Quantum, Rackspace has more flexibility for
delivering private networking capabilities into the cloud.
