Hi Client, Current ironic call is for add/delete baremetl server, not with auto-scale. As we discussed in another thread. What I'm thinking is related with auto-scale baremetal server. In my mind, the logic can be 1. Nova scheduler determines scale up one baremetal server. 2. Nova scheduler

I think there also needs to be a scalability best practise and reference architecture. Benchmarking allows us to identify problems with the code but we also need some community wisdom on how to deploy at scale. Does this fit within Rally or can you advise where this community wisdom should be

I think there is a need for an incompatible change review process which includes more of the community than just those performing the code reviews. This kind of change can cause a lot of disruption for those of us running clouds so it is great to see that you are looking for more input. In the

I think the better way is save meters as a field in resource table. You can look at MongoDB model and may get some ideas. Beside above, sql backend can introduce Memcache to improve performance. IMO, the best way may be redesign the sql model to match workload. On Sat, Dec 28, 2013 at 6:51 PM,
