Day 2 @ J1
Introduction to Play frameworkJames Ward
James Ward gave a good overview of the Play framework (Apache licensed) and deploying to Heroku. This is a rapid application platform targetting Scala and Java developers, with a focus on simplicity, async services (via Netty) and tight logical coupling to HTTP converations. These features help to create base stateless applications that scale horizontally easily. It's interesting to see scalability and performance requirements coming into application development frameworks.
I'd say this framework is worth a look if you're familiar with, or planning a migration to Scala. I'd be concerned about any coupling to Heroku and would want to look more into running Play applications on separate PaaS offerings.
