Hi all, At summit in Hong Kong we had a design session where we discussed adding multi-region orchestration support to Heat. During the session we had really heated discussion and spent most of the time on explaining the problem. I think it was really good starting point and right now more people have better understanding for this problem. I appreciate all the suggestions and concerns I got from you. I would like to continue this discussion here on the mailing list. I updated the etherpad after the session. If I forgot about something or wrote something that is not right feel free a please tell me about it.
