 ## Before you begin
 
-Azure Load Balancer is available in two SKUs: *Basic* and *Standard*. The *Standard* SKU is used by default when you create an AKS cluster. The *Standard* SKU gives you access to added functionality, such as a larger backend pool, [multiple node pools](use-multiple-node-pools.md), [Availability Zones](availability-zones.md), and is [secure by default][azure-lb]. It's the recommended load balancer SKU for AKS.

-For more information on the *Basic* and *Standard* SKUs, see [Azure Load Balancer SKU comparison][azure-lb-comparison].

-This article assumes you have an AKS cluster with the *Standard* SKU Azure Load Balancer. If you need an AKS cluster, you can create one [using Azure CLI][aks-quickstart-cli], [Azure PowerShell][aks-quickstart-powershell], or [the Azure portal][aks-quickstart-portal].

 > [!IMPORTANT]
 > If you'd prefer to use your own gateway, firewall, or proxy to provide outbound connection, you can skip the creation of the load balancer outbound pool and respective frontend IP by using [**outbound type as UserDefinedRouting (UDR)**](egress-outboundtype.md). The outbound type defines the egress method for a cluster and defaults to type `LoadBalancer`.
