I do like micro services. As a general architecture for new systems, but also as wrappers around existing legacy applications. It makes integration and evolution of old applications a lot smoother with newer technology stacks.

Once fully "micro serviced" http://yobriefca.se/blog/2013/04/29/micro-service-architectu... you can replace/evolve one service at the time, instead of more costly and risky whole applications at the time. A natural pattern to evolve those chosen services is strangler application pattern also described by Fowler http://martinfowler.com/bliki/StranglerApplication.html
