 With App Service Environment v3, the pricing model varies depending on the type of App Service Environment deployment you have. The three pricing models are:
 
 - **App Service Environment v3**: If the App Service Environment is empty, there's a charge as though you have one instance of Windows I1v2. The one instance charge isn't an additive charge but is applied only if the App Service Environment is empty.
-- **Zone redundant App Service Environment v3**: There's a minimum charge of nine instances. There's no added charge for availability zone support if you have nine or more App Service plan instances. If you have fewer than nine instances (of any size) across App Service plans in the zone redundant App Service Environment, the difference between nine and the running instance count is charged as additional Windows Isolated 1 v2 instances.

 - **Dedicated host App Service Environment v3**: With a dedicated host deployment, you're charged for two dedicated hosts per our pricing when you create the App Service Environment v3 and then, as you scale, you're charged a small percentage of the Isolated v2 rate per core.
 
 Reserved Instance pricing for Isolated v2 is available and is described in [How reservation discounts apply to Azure App Service](../../cost-management-billing/reservations/reservation-discount-app-service.md). The pricing, along with Reserved Instance pricing, is available at [App Service pricing](https://azure.microsoft.com/pricing/details/app-service/windows/) under the Isolated v2 plan.
