Change and Configuration Management clustered environment
You can set up a clustered environment to host a Jazz® Team Server and multiple Change and Configuration Management (CCM) WebSphere Liberty nodes.
The CCM applications must be installed on multiple IBM® WebSphere® Liberty servers and connected by using an MQTT broker, which enables synchronization across the nodes. A load balancer is used as a front-end URL, which accepts connections and distributes the requests to one of the back-end CCM nodes. The host name of the load balancer is used as public URL for the CCM applications during setup. The distributed cache microservice (DCM) invalidates cache entries across the cluster nodes.
The following diagram illustrates the approach to clustering.
To install the Change and Configuration Management applications in a clustered environment, continue with the Interactive Installation Guide.
For best practices and additional information about the CCM clustering, see this Deployment wiki document.
