Good news, everyone! I have created the missing whiteboard diagram that we all needed at the design summit:

https://wiki.openstack.org/wiki/Heat/Blueprints/Multi_Region_Support_for_Heat/The_Missing_Diagram

I've documented 5 possibilities. (1) is the current implementation, which we agree we want to get away from. I strongly favour (2) for the reasons listed. I don't think (3) has many friends. (4) seems to be popular despite the obvious availability problem and doubts that it is even feasible. Finally, I can save us all some time by simply stating that I will -2 on sight any attempt to implement (5).

1 status quo isn't terrible
2 +2 simple robust
3 -2 this means another daemon and seems overly complex
4 I don't think it will be possible to allow VM->heat communication for things like signaling. Without signaling, this is DOA 5 seems complex to implement and I don't see a clear path to get there from where we are today

Out of the options, #2 looks like the best choice.

I would -2 option #3 if I saw it hit the review queue.

When we're discussing this, please mention explicitly the number of the model you are talking about at any given time.

If you have a suggestion for a different model, make your own diagram! jk, you can sketch it or something for me and I'll see if I can add it.

cheers,
Zane.
