This model consists of two sub cluster domains as worker domain and management domain. These sub domains take up load according to a defined load balancing algorithm and auto-scales according to the load on its nodes.
Single Cluster with two Load Balancers
This model consists of a single cluster, where a selected node works as both a worker and a manager. This worker node requires two load balancers and configured in read-write mode, while the other worker nodes are set up in read-only mode. The management node also should be a well-known member in the non-management worker nodes so that state replication and cluster messaging works.
Shown below is the minimum configuration instructions to cluster two WSO2 Application Server instances. The cluster consists of two sub cluster domains as worker/management and is fronted by a single load balancer. Altogether, we will be configuring three instances as follows:
