- you show them OpenID/OAuth form for their cloud provider
- guide them through the creation of an account if necessary
- you get the token, that permits your server to create cloud resources on behalf of the user
- you go ahead and create their services for them
- potentially store the token to be able to update the apps automatically

Problem is: most clouds don't let you easily create an account, so "guide them through the creation of an account" might be impossible without leaving the browser.
