Vert.x is the framework for the next generation of asynchronous, effortlessly scalable, concurrent applications.
Some of the key highlights include:
No more worrying about concurrency. Vert.x allows you to write all your code as single threaded, freeing you from the hassle of multi-threaded programming, yet unlike other asynchronous framework it scales seamlessly over available cores without you having to fork.
Vert.x has a super simple, asynchronous programming model for writing truly scalable non-blocking applications.
Vert.x provides real power and simplicity, without being simplistic. No more boilerplate or sprawling xml configuration files.
If you don't want the whole vert.x platform, vert.x can also be used as a lightweight library in your Java or Groovy applications
