Hi Duncan,
Thanks for the feedback. The design is made in a way which will support quota-classes and more complex use cases *in the future*. Yet, we do not intend to alter how per project and per project per user quotas work, meaning that quota classes will work for these cases.
In our design, the central quota management system stores hard limits for domain quotas and informs these values to the services using a REST API, in turn the services implements domain quota enforcement.

Cheers,

Subject: Re: [openstack-dev] [Keystone] Feedback wanter on Domain Quotas

The quota model within cinder has moved on, and we now have per-volume type quotas in the pipeline... How can this be kept in sync with a central quota management system? We need to be able to register quota classes on the fly

Hi All,
We have been working in updating our blueprint to accept all the good feedbacks we received at the summit. The BP https://wiki.openstack.org/wiki/DomainQuotaManagementAndEnforcement is almost done. We are proposing a way to O~S to have quotas at domain level and it impacts Keystone, Nova, Cinder and Quantum. The enforcement of quotas - the part that was most discussed in Portland will only change based on your feedbacks.
The shop has been opened and we are waiting for your feedbacks.

Thanks and Kind regards,
