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
- [guava] (https://code.google.com/p/guava-libraries/)
- [guice] (https://code.google.com/p/google-guice/)
- [jersey] (http://jersey.java.net) REST
- [jetty] (http://jetty.codehaus.org/jetty) servlet container
- [jmeter] (http://jmeter.apache.org) jmeter load test
- [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 run standalone in a data center, but is optimized for an Amazon Web Services environment.
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
