[Lagom](http://lightbend.com/lagom) is the implementation of the described concepts. To find a good example to implement a Microservices based system with Lagom, we just needed to look into Eric Evans' book [Domain-Driven Design: Tackling Complexity in the Heart of Software](http://www.amazon.com/Domain-Driven-Design-Tackling-Complexity-Software/dp/0321125215) and use the discussed example, the [Cargo Tracker](http://dddsample.sourceforge.net/). The example in this repository follows this idea and is meant to be a starting point to build a full blown Lagom based cargo tracker. + +### Further Readings +* [How to make "Just right easier with Microservices"](https://www.oreilly.com/ideas/how-to-make-just-right-easier-with-microservices) +* [Developing Reactive Microservices](http://www.oreilly.com/programming/free/developing-reactive-microservices-signup.html) +* [Reactive Microservices Architecture](https://www.lightbend.com/reactive-microservices-architecture) + +### Community Contributions +Contributions welcome!
