Notes & disambiguation

  • Microsoft retired both Azure Basic Load Balancer and Azure Basic SKU Public IP addresses on September 30, 2025, requiring workloads (outside of Cloud Services Extended Support) to upgrade to Standard Load Balancer (`sku.name: 'Standard'`) and Standard Public IPs with secure-by-default network security group (NSG) and explicit outbound NAT rules.
  • Following the April 28, 2023 deprecation announcement, Microsoft retired Azure Application Gateway v1 SKUs (`Standard` and `WAF` v1 tiers) on April 28, 2026 in favor of Application Gateway v2 (`Standard_v2` and `WAF_v2`), which adds autoscaling, availability zone redundancy, static VIPs, and 5x faster TLS offload.
  • While the ARM resource types (`Microsoft.Network/loadBalancers`, `Microsoft.Network/publicIPAddresses`, `Microsoft.Network/applicationGateways`), CLI groups (`az network lb`, `az network public-ip`, `az network application-gateway`), and Terraform resources (`azurerm_lb`, `azurerm_public_ip`, `azurerm_application_gateway`) keep the same names, their legacy `Basic` and v1 `Standard`/`WAF` SKU values are retired.
