Setting Up Two ActiveMQ Artemis Clusters in the Same Network: A Comprehensive Guide

In many organizations, it is common to have separate environments for development (Dev), quality assurance (QA), production, and staging. When using ActiveMQ Artemis, it is essential to maintain the separation between these environments to avoid any potential conflicts and ensure the stability of each system. This guide will guide you through the steps required to set up two separate ActiveMQ Artemis clusters within the same network: one for Dev and another for QA.

The Problem: Isolating Clusters

You may find yourself in a situation where you need to establish two clusters consisting of several nodes in the same network. For example, you might want to create one for development and another for QA. The challenge lies in isolating the two clusters to ensure that nodes in the QA cluster do not interfere with or communicate with the nodes in the Dev cluster.

Here’s a brief rundown of your initial configuration, featuring key components:

The Solution: Configuring Isolated Clusters

To achieve isolation between your Dev and QA clusters, the most crucial step is ensuring that the discovery and broadcast groups do not overlap. Here’s how to do it:

1. Change the Group Ports

Changing the group-port settings in both the broadcast and discovery groups from the default value (9876) to a different value, such as 9877, will be sufficient to separate the Dev and QA clusters. Ensure that each cluster has its unique port number:

Broadcast Group for QA: Change the port to a unique number that does not conflict with the Dev cluster.

Discovery Group for QA: Similarly, set a distinct port for the discovery group.

2. Cluster Connection Name

While you may consider changing the name of the cluster-connection, it is primarily for organizational purposes. Keeping it distinct can help with managing configurations, but it does not impact the cluster's functionality directly.

Consider Different Names: For example, use my-cluster-dev and my-cluster-qa for clarity between environments.

3. Review Broadcast and Discovery Group Names

Like cluster connection names, the names of the broadcast and discovery groups can also be differentiated to prevent confusion. For example, you could use names like bg-dev and bg-qa to avoid mix-ups.

4. Verify Network Accessibility

Ensure that the nodes in each cluster can communicate within their environment while remaining isolated from each other. Properly configuring firewall rules or using virtual private networks (VPNs) can support this.

Conclusion

By carefully adjusting the group-port settings and organizing your cluster naming conventions, you can effectively isolate your Dev and QA clusters in the same network using ActiveMQ Artemis. This approach not only enhances the stability of your messaging environment but also fosters better management and maintenance practices for your organizational needs.

Following this guide will help you set up a robust messaging architecture that aligns with best practices in cluster management.
