To achieve failover and redundancy, you can add multiple VMware Identity Manager virtual appliances in the VMware Identity Manager cluster. If one of the virtual appliances shuts down for any reason, VMware Identity Manager is still available.

You first install and configure the VMware Identity Manager virtual appliance, then you clone it. Cloning the virtual appliance creates a duplicate of the appliance with the same configuration as the original. You can customize the cloned virtual appliance to change the name, network settings, and other properties as required.

Before you clone the VMware Identity Manager virtual appliance, you must configure it behind a load balancer and change its Fully Qualified Domain Name (FQDN) to match the load balancer FQDN. Also, complete directory configuration in the VMware Identity Manager service before you clone the appliance.

After cloning, you assign the cloned virtual appliance a new IP address before powering it on. The cloned virtual appliance IP address must follow the same guidelines as the IP address of the original virtual appliance. The IP address must resolve to a valid host name using forward and reverse DNS.

All nodes in the VMware Identity Manager cluster are identical and nearly stateless copies of each other. Syncing to Active Directory and to resources that are configured, such as View or ThinApp, is disabled on the cloned virtual appliances.

1

Setting up a VMware Identity Manager cluster with three nodes is recommended.

2

When you install and configure VMware Identity Manager, you select an external database or the internal database. If your appliance is configured to use the internal database, you need to modify a few settings.

3

Before you clone the VMware Identity Manager virtual appliance, you must change its Fully Qualified Domain Name (FQDN) to match the load balancer FQDN.

4

Clone the VMware Identity Manager virtual appliance to create multiple virtual appliances of the same type to distribute traffic and eliminate potential downtime.

5

You must assign a new IP address to each cloned virtual appliance before you power it on. The IP address must be resolvable in DNS. If the address is not in the reverse DNS, you must also assign the host name.
