We have a tough messaging problem here though. I suspect many users wait until graduation to consider a real deployment. "Incubated" is viewed as immature / WIP / etc. That won't change quickly, even if we want it to. I think our intentions are already to not graduate something that isn't ready for production. That doesn't mean we haven't made mistakes, but we're trying to learn and improve. We developed a set of *written* guidelines to stick to, and have been holding all projects up to them. Teams like Ceilometer have been very receptive to the process, have developed plans to fill gaps, and have been working hard on the issues. A hard rule for production deployments seems like a heavy rule. I'd rather just say that we should be confident that it's a production ready component, and known deployments are one such piece of input that would provide that confidence. It could also just be extraordinary testing that shows both scale and quality. -- Russell Bryant _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
