In an enterprise environment, the recommended VMware identity Manager machine configuration is to deploy a three-node cluster of the VMware Identity Manager service for high availability. After the first IDM node is installed, configured, and tested behind the load balancer, a script is run on the first node to create a copy of the first instance. This copied file is used to create the other nodes in the cluster.
The VMware Identity Manager architecture diagram demonstrates how you can deploy the VMware Identity Manager environment.
