Comment 1 for bug 1058510

This was discussed at length at UDS-Q, as part of this blueprint:

https://blueprints.launchpad.net/ubuntu/+spec/servercloud-r-juju-resource-map

It wasn't worked on because of the decision to focus on the Go port, but it is still needed. I've re-targetted it at R and proposed it for UDS-R.

We can use https://cloud-images.ubuntu.com to lookup image IDs on public clouds, but we will also need to offer users the ability to have a local resource map for private clouds. There is also a need to map instance types to their constraints in EC2, since Amazon does not offer this via an API.
