Built-in high availability

High availability is built in, so no extra load balancers are required and there’s nothing you need to configure.

Availability Zones

Azure Firewall can be configured during deployment to span multiple Availability Zones for increased availability. With Availability Zones, your availability increases to 99.99% uptime. For more information, see the Azure Firewall Service Level Agreement (SLA). The 99.99% uptime SLA is offered when two or more Availability Zones are selected.

You can also associate Azure Firewall to a specific zone just for proximity reasons, using the service standard 99.95% SLA.

There’s no additional cost for a firewall deployed in more than one Availability Zone. However, there are added costs for inbound and outbound data transfers associated with Availability Zones. For more information, see Bandwidth pricing details.

Azure Firewall Availability Zones are available in regions that support Availability Zones. For more information, see Regions that support Availability Zones in Azure
