A Vert.x event-bus is a light-weight distributed messaging system which allows different parts of your application,
or different applications and services to communicate with each in a loosely coupled way.
<p>
An event-bus supports publish-subscribe messaging, point-to-point messaging and request-response messaging.
<p>
Message delivery is best-effort and messages can be lost if failure of all or part of the event bus occurs.
<p>
Please refer to the documentation for more information on the event bus.
