In the AWS environment, we can deploy and also perform HA between two different Fortigate Instances residing in two different Availability Zones. One FortiGate unit acts as a master/primary node and other as a slave/secondary node. This HA is called “Unicast HA” specific to the AWS environment in comparison to an equivalent feature provided by physical FortiGate units. The FortiGates run heartbeats between dedicated ports and synchronize OS configurations. When the primary node fails, the secondary node takes over as the primary node.
This video will showcase the Fortigate HA in AWS environment consisting of two different Availability Zones.
