I have seen that one of the things you have on the roadmap is service brokering:
From what I understand waypoint would call unto the given platform to provision said resource for the app and thereafter configure it to use that resource.
It would be great to have maybe a smaller clone of that resource for each the my unreleased branches that can be destroyed ounce the branch is released or using the production resource. Here I am thinking of databases as an example.
I could clone the production database, add a sample of the data from the production database and apply new migrations if any using a hook. Then I could run my acceptance tests on an environment that is very similar to production.
