Azure Basic Load Balancer will be retired

On 30 September 2025, Azure Basic Load Balancer will be retired. You can continue to use your existing Basic Load Balancers until then, but you’ll no longer be able to deploy new ones after 31 March 2025.

To keep your workloads appropriately distributed, you’ll need to upgrade to Standard Load Balancer, which provides significant improvements including:

  • High performance, ultra-low latency, and superior resilient load-balancing.
  • Security by default: closed to inbound flows unless allowed by a network security group.
  • Diagnostics such as multi-dimensional metrics and alerts, resource health, and monitoring.
  • SLA of 99.99 percent availability.

Basic SKU public IP addresses will be retired

On 30 September 2025, Basic SKU public IP addresses will be retired in Azure. You can continue to use your existing Basic SKU public IP addresses until then, however, you’ll no longer be able to create new ones after 31 March 2025.

Standard SKU public IP addresses offer significant improvements, including:

  • Access to a variety of other Azure products, including Standard Load Balancer, Azure Firewall, and NAT Gateway.
  • Security by default—closed to inbound flows unless allowed by a network security group.
  • Zone-redundant and zonal front ends for inbound and outbound traffic.
