Cloud Foundry Welcomes Scala Developers

The Cloud Foundry PaaS now supports the Scala programming language, and its related frameworks. According to the announcement, “most” Scala applications written to Lift and Spring will now deploy to Cloud Foundry without modification. Scala web apps that do not use application services (for example, a database) should deploy to Cloud Foundry without modification, regardless of the framework used, or even if no framework is used at all.

Scala support is already available in the Cloud Foundry repository and will be live at the Cloud Foundry website, over the next few weeks.
