Generally Available: Network isolated cluster in AKS

Today, you can control an AKS cluster's egress traffic using Azure Firewall. While this configuration is intended to isolate the cluster to protect sensitive business or customer data, it adds an additional layer of management complexity and cost.   

AKS now provides the option to use network isolated clusters to simplify the process of restricting network access and reduce the risk of unintentional exposure of the cluster's public endpoints to prevent security breaches.
