Prerequisites

To configure FortiWeb HA cluster on OCI, you need to prepare the following:

• Creating a virtual cloud network.
• Creating a security list
• Deploying two FortiWeb-VM instances in the same region. See Deploying FortiWeb-VM on OCI for more information.
  It's recommended to deploy the FortiWeb-VMs in different availability domains to ensure high availability even in rare cases when one of the availability domains is down.

Please refer to Deploying FortiWeb on OCI for instructions on how-to.
