Deploying the Mosquitto MQTT message broker on Red Hat OpenShift, Part 2

The first half of this article introduced the Mosquitto  Message Queuing Telemetry Transport  (MQTT) message broker and showed how to build Mosquitto into an image suitable for use in a container. In this second half of the article, you will configure and deploy the Mosquitto image into an application that runs on Red Hat OpenShift. You can obtain the files for the example from my GitHub repository.

Deploying the Mosquitto MQTT message broker on Red Hat OpenShift, Part 1

Mosquitto is a lightweight message broker that supports the Message Queuing Telemetry Transport  (MQTT) protocol. Mosquitto is widely used in Internet of Things (IoT) and telemetry applications, where a fully-featured message broker like Red Hat AMQ would be unnecessarily burdensome. Mosquitto also finds a role as a message bus for interprocess communication in distributed systems. Because it avoids complex features, Mosquitto is easy to tune and handles substantial application workloads with relatively modest memory and CPU resources.

Message broker integration made simple with Red Hat Fuse

Message broker integration made simple with Red Hat Fuse

This article presents a sample integration between Red Hat AMQ 7 and IBM MQ, using Red Hat Fuse 7 for the integration. Traditionally, developers have used resource adapters for message bridging with external systems. A resource adapter is a system library that provides connectivity to an enterprise information system (EIS). Similar to how a Java Database Connectivity (JDBC) driver provides connectivity to a database management system, a resource adapter plugs into an application server such as Red Hat JBoss Enterprise Application Platform (JBoss EAP). It then connects the application server, enterprise information system, and the enterprise application.
