I think my head just exploded. There are so many possible ways for this to be useful for people managing VMs in Azure it's overwhelming.
What is my resource ID? What are my managed disk IDs? Are they premium disk? What image was used to create me? Who manages me? Where am I located?
*BOOM*

[@tumelomotsikelane]

Very useful. I never thought VMs could see their Azure metadata

[@craigmcgrath4289]

Nice explanation. Looking forward to trying it out. :)

[@iamdedlok]

This is fascinating, thanks John! Looks very useful.

Lol it’s not that old

Two questions regarding this great feature: does the request to this IP also work from Azure App Serives? And: will there also show up a scheduled event when a VM will be updated?

[@NTFAQGuy]

This is for VM only in terms of support. Other services run on VMs but likely not exposed. No scheduled event in the guest.

[@FalcoPunch182]

@@NTFAQGuy sorry not updated. I meant if there is a scheduled event when the VM will be backed up via Azure Backup. This would make it easier getting to application consistent backup states.

[@NTFAQGuy]

@@FalcoPunch182 no but you don't need it. azure backup calls vss etc to make app consistent.
