-The new gateway SKUs also support other deployment options to best match your needs. When you create a virtual network gateway by using the new gateway SKUs, you can deploy the gateway in a specific zone. This type of gateway is called a *zonal gateway*. When you deploy a zonal gateway, all the instances of the gateway are deployed in the same availability zone.

 ## ExpressRoute scalable gateway (preview)
 
-The ErGwScale virtual network gateway SKU enables you to achieve 40-Gbps connectivity to VMs and private endpoints in the virtual network. This SKU allows you to set a minimum and maximum scale unit for the virtual network gateway infrastructure, which autoscales based on the active bandwidth or flow count. You can also set a fixed scale unit to maintain a constant connectivity at a desired bandwidth value.

-ErGwScale supports both zonal and zonal-redundant deployments in Azure availability zones. For more information about these concepts, review the [Zonal and zone-redundant services](../reliability/availability-zones-overview.md#zonal-and-zone-redundant-services) documentation.
