FortiGate on AWS with HA

[sneharaj]

Hi Team, 

  I wish to understand if FortiGate does support high availability. I wanted to configure FortiGate VM as a VPN gateway on AWS to serve site to site VPN traffic. if due to some reason if one AWS Az goes down, can we configure FortiGate on active-passive mode on different AWS Az? 

  If so do I need to subscribe froti manger also for managing the FortiGate VM ?

I have not worked with Fortigate in AWS but I have with Azure so I'll share my experience. I don't know how to create active-passive HA in Azure cloud. What I did was to put a load balancer in front and after the pair of Fortigate VM. I've created condition on the LB to only forward traffic the Fortigate A and failover to Fortigate B only when the health check on LB fails.
