Deploying FortiProxy-VM active-active (config-sync) HA on AWS across AZs with load balancing
To achieve more security and reliability to the existing cloud infrastructure, use an AWS external load balancer (ELB) for the FortiProxy-VM HA cluster. By deploying two FortiProxy-VMs and associating them with an ELB, and traffic is balanced between the two. If one FortiProxy-VM fails, the other handles traffic.
Setting the FortiProxy instances in separate availability zones also allows the HA cluster to recover in the event of a catastrophic failure. In the case that both FortiProxies are located in the same Availability Zone and that AZ happens to fail, then both FortiProxies would go down and HA would be useless.
The following steps walk you through the configuration process of FortiProxy-VM active-active (config-sync) HA on AWS across AZs with load balancing.
