Play is a high-velocity web framework for Java and Scala that follows the MVC pattern and focuses on performance, reliability, and scalability. It aims to improve developer productivity through convention over configuration, hot code reloading, and browser error display. Play uses an asynchronous, non-blocking architecture built on Akka and Netty and is stateless like HTTP. The presentation introduces Play and demonstrates installing Play and using its controller layer, template engine, models, and WS API.

1. Play != Servlet
2. Play != Library
3. Play is the Platform!

3. Why is Play relevant?
The need of a web framework for Building Modern Web
Apps (HTML5, Coffeescript, Less, Websockets, Comet,
JSON, etc)
Event Driven (Built on top of Akka and Netty (NIO)
● Asynchronous
● Non-Blocking
Play is stateless because http is stateless.

4. Let’s Play!

Some stuff worth to have a look at...
