Akka

Writing concurrent programs is hard. Having to deal with threads, locks, race conditions, and so on is highly error-prone and can lead to code that is difficult to read, test, and maintain. This post provides an introductory guide to the Scala-based Akka framework, showing (with code samples) how Akka facilitates and simplifies the implementation of robust, concurrent, fault-tolerant applications.

Web Developers often fail to consider the consequences of thousands of users accessing our applications at the same time. Perhaps it’s because we love to rapidly prototype; perhaps it’s because testing such scenarios is simply hard.

Regardless, I’m going to argue that ignoring scalability is not as bad as it sounds—if you use the proper set of tools and follow good development practices. In this case: the Play! framework and the Scala language.
