Application Gateway - active and passive

I have a application gateway with two backend pools. Backend Pool A has two VMs and Backend Pool B has two VMs. Will application gateway allow the VMs in pool A to be setup as active-passive and the same for pool B. The idea is that if the active VM in pool A has an outage then the traffic is routed to the other VM.

Hi,

You can achieve an active/pasive configuration with a Trafic Manager and two application gateways.

The Traffic Manager can monitor the health status of the two Application Gateways and redirect the trafic in case of failure:

Hope this helps!

Hello @JavaM-9790

I would suggest checking the two articles below about high availability using Traffic Manager + Application Gateway + Azure DNS:

https://docs.microsoft.com/en-us/azure/architecture/high-availability/reference-architecture-traffic-manager-application-gateway
https://docs.microsoft.com/en-us/azure/networking/disaster-recovery-dns-traffic-manager

I hope this helps!
