- In Azure, [availability zones](../reliability/availability-zones-overview.md#availability-zones) provide resiliency, distributed availability, and active-active-active zone scalability. To increase availability for your logic app workloads, you can [enable availability zone support](/azure/logic-apps/set-up-zone-redundancy-availability-zone), but only when you create your logic app. You'll need at least three separate availability zones in any Azure region that supports and enables zone redundancy. The Azure Logic Apps platform distributes these zones and logic app workloads across these zones. This capability is a key requirement for enabling resilient architectures and providing high availability if datacenter failures happen in a region. For more information, see [Build solutions for high availability using availability zones](/azure/architecture/high-availability/building-solutions-for-high-availability).
