The title might not be exactly buzzword-free, but our Docker-based prototype is a very concrete demonstration of using the dynamic service model of OSGi, as implemented in Apache Sling, to create a dynamically assembled front-end for multiple NoSQL databases. Combining relatively lightweight containers, dynamic OSGi services and the powerful ResourceProvider concept of Apache Sling make it possible to assemble very different backends as a unified data tree, with very little code.
Even if you are not using OSGi or some of the other technologies presented here, our demo system, available on GitHub for you to play with, is a useful demonstratation of modern service orchestration based on containers and distributed consensus systems.
