Retrieve load balancer information by using the Azure Instance Metadata Service

IMDS (Azure Instance Metadata Service) provides information about currently running virtual machine instances. The service is a REST API that's available at a well-known, non-routable IP address (169.254.169.254).

When you place virtual machine or virtual machine set instances behind an Azure Standard Load Balancer, use the IMDS to retrieve metadata related to the load balancer and the instances.

The metadata includes the following information for the virtual machines or virtual machine scale sets:

  • Standard SKU public IP.
  • Inbound rule configurations of the load balancer of each private IP of the network interface.
  • Outbound rule configurations of the load balancer of each private IP of the network interface.
