We are excited to announce the public preview of Instance Metadata Service in Azure’s West Central US region. Instance Metadata Service is a RESTful endpoint that allows virtual machines instances to get information regarding its compute, network and upcoming maintenance events. The endpoint is available at a well-known non-routable IP address (169.254.169.254) that can be accessed only from within the VM. The data from Instance Metadata Service can help with your cluster setup, replica placement, supportability, telemetry or other cluster bootstrap or runtime needs.
Previews are made available to you on the condition that you agree to the terms of use.
Read about it on the Azure blog.
