# The Most Popular Microservice (Is Written In Java)

One of the most popular microservice is Jenkins CI: 

Jenkins was initially created by a very small team (Kohsuke Kawaguchi)
Jenkins plays well with other services like GitHub, SVN, Git using HTTP and REST-like APIs. In fact Jenkins is very popular in non-Java environments.
The state is managed by each Jenkins instance individually in an own repository (JENKINS_HOME)
Services are exposed via Remote API
The UI is self-contained
Jenkins can be easily extended by an independent team
Jenkins is already packaged as a micro service: just launch the service with java -jar jenkins.war


However, I bet Kohsuke didn't knew the term "microservice" as he initially developed Hudson :-).
