Azure DevTest Labs has made enhancements designed to accommodate two upcoming retirements in Azure:
| Retirement | Date | Details |
|---|---|---|
| Azure Basic Load Balancer | September 30, 2025 | The Azure Basic Load Balancer will be retired. You can continue using your existing Basic Load Balancers until this date, but you will not be able to deploy new ones after 31 March 2025. For more information, please refer to the official announcement. |
| Basic SKU Public IP Addresses | September 30, 2025 | Basic SKU Public IP Addresses will be retired in Azure. You can continue using your existing Basic SKU public IP addresses until this date, but you will not be able to create new ones after 31 March 2025. For more information, please refer to the official announcement. |
Important
The enhancements in Azure DevTest Labs to support Azure's retirement of Basic Load Balancer and Basic SKU Public IP address are currently in preview. For more information about the preview status, see the Supplemental Terms of Use for Microsoft Azure Previews. The document defines legal terms that apply to Azure features that are in beta, in preview, or otherwise not yet released into general availability.
These retirements will not impact VMs with Private IPs. However, they will impact VMs with Public or Shared IPs in the following ways:
Impact on VMs with Public IPs:
- Current Setup: When you create a Public IP VM, a Basic SKU Public IP address resource with dynamic IP allocation is created.
- New Setup: A Standard SKU Public IP address resource with static IP allocation will be created when you create a Public IP VM. Each VM with a Public IP will be assigned its own public IP address, allowing direct access via RDP or SSH. You need to create and configure a Network Security Group (NSG) to allow inbound traffic such as RDP or SSH connection. To learn more about how to create and configure NSGs, please check Create, change, or delete a network security group.
- How to View the SKU:
- Go to the Azure compute view of the VM under Network settings.
- Click on the link of the Public IP resource.
- In the resource overview page, you can see the SKU type as Standard.
Impact on VMs with Shared IPs:
- Current Setup: All VMs created with Shared IPs are placed in the same resource group, which has one assigned Basic SKU public IP address. DevTest Labs automatically creates a Basic load balancer to manage traffic for these VMs. When a VM with a shared IP is added to a subnet, it is automatically added to the load balancer and assigned a TCP port number on the public IP address, forwarding to the SSH port on the VM.
- New Setup: A Standard SKU load balancer will be created and used instead of a Basic Load Balancer. You need to create and configure a Network Security Group (NSG) to allow inbound traffic such as RDP or SSH connection. To learn more about how to create and configure NSGs, please check Create, change, or delete a network security group.
- How to View the SKU:
- Go to the Azure compute view of the VM under Load Balancing.
- Click on the link of the load balancer resource.
- In the resource overview page, you can see the SKU type as Standard.
These changes in Azure DevTest Labs are being rolled out to different regions in phases. We expect to complete the rollout by March 31, 2025.
