@Jeff Barr
If you are still collecting use cases, here is an old one, which is the opposite of shlomo’s, due to devpay you want to force them into different az’s:

Revisiting this use case, I think I might use consolidated billing rather than devpay – but I am not sure since my use case is extra-company, and consolidated billing seems intra-company (e.g. 20 linked account limit, credit card required).

HTH?

@Jeff Barr,

Sure, happy to share a use case:

When two accounts interact with each other on the internal EC2 network, such as the Production account pulling the latest info from the Staging account, you want to minimize the cost of the data transfer between them. This is only possible if you know the correspondence of the physical availability zones.

Readers are welcome to submit more use cases as comments.

I would be very interested in hearing about cases where people need to match EC2 availability zones across customer accounts. Feel free to email me (jbarr at amazon dot com) if you have an actual use case and I’ll forward the info to the development team.
