Let us take a closer look at the ActiveMQ failover and NFS with the support of our Server management support services at Bobcares.

ActiveMQ failover and NFS

In an ActiveMQ messaging system, this configuration enables for high availability and fault tolerance.

When the primary broker becomes unavailable, ActiveMQ includes a feature called failover transport, which allows for automatic reconnection and failover to a backup broker.

We may store ActiveMQ message data and configuration files on a shared NFS file system accessible by many ActiveMQ brokers by integrating this failover capability with NFS.

How does ActiveMQ failover works with NFS?

Here’s a rundown of how the ActiveMQ failover with NFS configuration works:

1. Shared NFS Storage:

   Firstly, create an NFS file system that multiple ActiveMQ broker instances may access. The message data and configuration files will be stored in this shared storage.
2. Multiple ActiveMQ Brokers:

   After that, we have to set up and install multiple ActiveMQ broker instances on distinct hosts. For reading and writing message data, each broker instance will connect to the common NFS file system.
3. Failover Configuration:

   Configure the failover transport method for the ActiveMQ brokers. This setting defines a list of broker URLs to which the broker should connect, including primary and backup brokers.

   When the primary broker becomes unavailable, the failover transport immediately switches to the backup broker.
4. Message Persistence:

   Configure the ActiveMQ brokers to store messages on a shared NFS file system. This guarantees that messages are saved on shared storage and may be accessed by any of the cluster’s ActiveMQ brokers.
5. Load Balancing:

   Finally, to disperse the message processing burden, we may additionally implement load balancing among the ActiveMQ brokers if necessary.

   We can achieve this by employing various load balancing strategies, such as employing a separate load balancer positioned ahead of the ActiveMQ brokers or using a dedicated load balancing protocol like MQTT or AMQP.

We may achieve high availability and fault tolerance in the messaging system by integrating ActiveMQ’s failover transport capability with NFS as shared storage.

If one broker fails, the remaining brokers in the cluster immediately take over message processing and handling, ensuring continuous message delivery and system functionality.
