Amazon VPC Peering

In one line

Creating the peering costs nothing. Bytes that cross an AZ or a Region boundary do.

What gets missed

Same-AZ peering is free even across accounts. Cross-AZ is metered on both sides, and since April 2025 lands on VpcPeering-In/Out-Bytes rather than DataTransfer-Regional-Bytes.

Bills the same way

These services turn exactly the same meters, so what you learn here transfers.
