In a busy night of Azure announcements, Microsoft said that we can now peer two Azure VNets to connect them without using a VNet-to-VNet VPN. This in-preview feature will reduce costs and complexity.
I have yet to find any technical details, but this will be a great addition. I like that it supports ASM and ARM connections via different subscriptions – I can run RemoteApp in Open (ASM) to provide remote access to services in CSP (ARM).
As usual, you should carefully plan your VNet network address to plan for scalability – don’t be the idiot that deploys the entirety of 10.0.0.0 to a single VNet/subnet!
Note that I have been unable to find technical documentation yet.
ARM vnet can be peered with ARM VNET in same region but 2 ASM VNET cannot be peered with Each other.
VNET should be in the same region irrespective of Different subscription. They can be in ASM or ARM.
Just saw this – posted on github roughly 20 hours ago.

Thanks, I linked to that this morning in a newer article.
Anyone tested the VNET peering and successfully with ASM to ARM VNET peering.
