Three node cluster

This section describes a common high availability deployment used in mid-sized deployments. In this type of deployment, all of the OpenIAM services, infrastructure is replicated on each of the three Linux hosts that make up the cluster. The database is external to the cluster and can have its own cluster.

If integration to Active Directory or another Microsoft application is required, then a Windows VM should be used to host the connector. In this example, we will use the Active Directory PowerShell connector.

Note: This diagram is limited to integration with one application using common ports. The list of ports can change if integration with other applications is required.
