Explore the capabilities of Play framework for building real-time web applications on the JVM in this GOTO 2012 conference talk. Dive into the framework's architecture, which emphasizes simplicity and high scalability. Learn about real-time web technologies like WebSockets, Server-sent events, and Comet, and how they enable continuous bidirectional client/server communication. Discover how Play's reactive programming model and JVM foundation contribute to creating robust, responsive applications that scale easily. Compare Play's development approach to other frameworks, and gain insights into its programming model, including streams, Java functions, and reactive stream manipulation. Examine practical examples, such as real-time monitoring and interleaving streams, and understand how Play handles data types, REST, and JSON. Get introduced to the Play community, website, and tools like SBT for Java developers.
