Azure - Azure Firewall HA setup

Question

Hello,

I would like to know, if I set up two AZs in Azure Firewall setup will it deploy 2 instances of Azure Firewall to achieve high availability? And according to that I will pay double price?

Thank you for asking your question in Microsoft Q & A.

Azure Firewall has built-in high availability in all tiers, including basic.

Also, there is no extra cost for a firewall deployed in more than one availability zone.

To answer your question, yes, Azure Firewall will be deployed using two virtual machine backend instances for basic tier.
