Flux Capacitor is a Java-based distributed application demonstrating the following Netflix Open Source components (in alphabetical order):

• [archaius] (https://github.com/Netflix/archaius) configuration
• [astyanax] (https://github.com/Netflix/astyanax) cassandra client
• [blitz4j] (https://github.com/Netflix/blitz4j) asynchronous logging
• [curator] (https://github.com/Netflix/curator) zookeeper client
• [eureka] (https://github.com/Netflix/eureka) discovery service
• [exhibitor] (https://github.com/Netflix/exhibitor) zookeeper administration
• [governator] (https://github.com/Netflix/governator) guice-based dependency injection extensions
• [hystrix] (https://github.com/Netflix/hystrix) circuit breaker
• [karyon] (https://github.com/Netflix/karyon) common base server
• [ribbon] (https://github.com/Netflix/ribbon) eureka-based REST client
• [servo] (https://github.com/Netflix/servo) metrics

In addition to the Netflix OSS components listed above, Flux Capacitor uses the following Open Source components:

• [graphite] (http://graphite.wikidot.com) metrics
• [jersey] (http://jersey.java.net) REST
• [jetty] (http://jetty.codehaus.org/jetty) servlet container
• [netty] (http://netty.io) io server
• [tomcat] (http://tomcat.apache.org/) servlet container

This project demonstrates many aspects of a complete distributed, scalable application from dynamic configuration to real-time metrics.

This app can be deployed standalone, in a data center, or in an AWS (Amazon Web Services) environment with just a few configuration changes.

The following project layout is typical of many distributed applications:

• Customer-facing REST-based edge service
• Uses Jetty as the servlet container and messaging engine

• Internal REST-based middletier service called by the edge service
• Uses Netty as the messaging engine

• Shared classes between edge and middletier
