In April 2008 Google launched its public Platform-as-a-Service (PaaS) cloud computing infrastructure called App Engine (GAE).
At that time the platform only supported Python language.
Exactly one year later, Google added a second supported language: Java.
Now the company is working to expand the GAE capabilities even more: SDTime reports in fact that Google plans to introduce support for Ruby on Rails, Clojure and Scala.
These languages already work inside GAE but only on the App Engine Java Virtual Machine (JVM), but Fred Sauer, Developer Advocate at Google, said that they may run natively.
This may impact other public PaaS providers like Heroku, which offers cloud hosting for Ruby applications and which recently secured a $10M funding in its Round B.
