Clustering
To enable clustering for an application that’s been deployed to Runtime Fabric, there must be a minimum of two replicas. Clustering can be enabled from the Runtime Manager UI or can be specified in the Mule Maven plugin when you’re deploying the application.
Deploying replicas across nodes
This option ensures that an application with multiple replicas is deployed across the nodes in the cluster. This option can be enabled from the Runtime Manager UI or can be specified in the Mule Maven plugin when you’re deploying the application.
