"If you build a Scala web app that does not use application
services such as a database, the company says, you can deploy it to
Cloud Foundry without any changes. Registered developers can see an
example here. Of course, most applications do use services. But if
you "externalize" services with the Lift framework or tap
'auto-reconfiguration support' with Spring, you should also be able
to deploy without modification.
"VMware has already added Scala support to the Cloud Foundry
repository, and it will be added to the live service (still
officially a beta) in the coming weeks."
