“Scala is well suited for cloud computing applications,” said Martin Odersky. “Its unique integration of object-oriented and functional language features makes it a scalable and productive way to code for cloud environments like Heroku.”
Adam Wiggins, Heroku co-founder and CTO declared “The Scala programming language, Typesafe's Akka middleware, and Heroku's platform are a powerful combination for developers building and delivering the next generation of applications and services on the web.”
This year Heroku, originally a Ruby PaaS provider, has added support for JavaScript/Node.js, Clojure, Java, and Python/Django.
