Java and Play! on Heroku
At Heroku, we believe you should be able to choose the best programming language for your application. That’s why we are transforming Heroku into a ploygot platform. We are excited to announce that Java is now available on Heroku as our fourth official language! We also want to introduce Play!, a Java based web framework that is as easy and elegant as Rails for Ruby.
以上为heroku官方的通知，在Ruby，Python，PHP，Node.js，Closure之后，heroku终于支持了Java语言。相信这一次升级会吸引更多的开发者使用heroku平台。
heroku所带来的便捷部署方式，提升开发者效率，改善上线速度，提高程序员生产率和生活质量，一度受到广泛好评。近半年heroku升级速度加快，从单一的ruby平台过渡到多语言平台，一举进入主流的云服务行列。
同时看到一个消息，facebook内置为开放平台用户在heroku上创建应用的功能，独立应用平台与内容平台将各施展所长。
