We hear about Microservices a lot nowadays. Its implementation requires us to deal with new challenges. A key question that comes with using microservices is how to handle interactions in an asynchronous way. The answer to that is messaging.

- Improved availability since the message broker buffers messages until the consumer is able to process them.
- Supports a variety of communication patterns including request/reply, notifications, request/async response, publish/subscribe, publish/async response and more.
One of the most famous products in messaging is JBoss A-MQ. Among the questions I receive from customers is whether it’s possible to run Red Hat JBoss A-MQ on Red Hat OpenShift.
