 Before you deploy your App Service Environment, think about the virtual IP (VIP) type and the deployment type.
 
-With an *internal VIP*, an address in your App Service Environment subnet reaches your apps. Your apps aren't on a public DNS. When you create your App Service Environment in the Azure portal, you have an option to create an Azure private DNS zone for your App Service Environment. With an *external VIP*, your apps are on an address facing the public internet, and they're in a public DNS. 
+With an *internal VIP*, an address in your App Service Environment subnet reaches your apps. Your apps aren't on a public DNS. When you create your App Service Environment in the Azure portal, you have an option to create an Azure private DNS zone for your App Service Environment. With an *external VIP*, your apps are on an address facing the public internet, and they're in a public DNS.  For both *internal VIP* and *external VIP* you can specify *Inbound IP address*, you can select *Automatic* or *Manual* options. If you want to use the *Manual* option for an *external VIP*, you must first create a standard *Public IP address* in Azure. 
 
-For the deployment type, you can choose *single zone*, *zone redundant*, or *host group*. The single zone is available in all regions where App Service Environment v3 is available. With the single zone deployment type, you have a minimum charge in your App Service plan of one instance of Windows Isolated v2. As soon as you have one or more instances, then that charge goes away. It isn't an additive charge.

-In a zone redundant App Service Environment, your apps spread across three zones in the same region. Zone redundant is available in regions that support availability zones. With this deployment type, the smallest size for your App Service plan is three instances. That ensures that there is an instance in each availability zone. App Service plans can be scaled up one or more instances at a time. Scaling doesn't need to be in units of three, but the app is only balanced across all availability zones when the total instances are multiples of three.

-A zone redundant deployment has triple the infrastructure, and ensures that even if two of the three zones go down, your workloads remain available. Due to the increased system need, the minimum charge for a zone redundant App Service Environment is nine instances. If you have fewer than this number of instances, the difference is charged as Windows I1v2. If you have nine or more instances, there is no added charge to have a zone redundant App Service Environment. To learn more about zone redundancy, see [Regions and availability zones](./overview-zone-redundancy.md).

-In a host group deployment, your apps are deployed onto a dedicated host group. The dedicated host group isn't zone redundant. With this type of deployment, you can install and use your App Service Environment on dedicated hardware. There is no minimum instance charge for using App Service Environment on a dedicated host group, but you do have to pay for the host group when you're provisioning the App Service Environment. You also pay a discounted App Service plan rate as you create your plans and scale out.

 With a dedicated host group deployment, there are a finite number of cores available that are used by both the App Service plans and the infrastructure roles. This type of deployment can't reach the 200 total instance count normally available in App Service Environment. The number of total instances possible is related to the total number of App Service plan instances, plus the load-based number of infrastructure roles.

 1. Search Azure Marketplace for *App Service Environment v3*.
 
-1. From the **Basics** tab, for **Subscription**, select the subscription. For **Resource Group**, select or create the resource group, and enter the name of your App Service Environment. For **Virtual IP**, select **Internal** if you want your inbound address to be an address in your subnet. Select **External** if you want your inbound address to face the public internet. For **App Service Environment Name**, enter a name. The name you choose will also be used for the domain suffix. For example, if the name you choose is *contoso*, and you have an internal VIP, the domain suffix will be `contoso.appserviceenvironment.net`. If the name you choose is *contoso*, and you have an external VIP, the domain suffix will be `contoso.p.azurewebsites.net`.

-1. From the **Hosting** tab, for **Host group deployment**, select **Enabled** or **Disabled**. If you enable this option, you can deploy onto dedicated hardware. If you do so, you're charged for the entire dedicated host during the creation of the App Service Environment, and then you're charged a reduced price for your App Service plan instances.
+3. From the **Hosting** tab, for **Physical hardware isolation**, select **Enabled** or **Disabled**. If you enable this option, you can deploy onto dedicated hardware. 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 specialized Isolated v2 rate per vCore. I1v2 uses two vCores, I2v2 uses four vCores, and I3v2 uses eight vCores per instance.
