AWS Transit Gateway attachment pricing

Question

Looking for some clarity on how Transit Gateway (TGW) to Transit Gateway pricing works. Do we configure/price that as 1 attachment per TGW? Or 1 attachment total between the 2 TGW instances?

With regular VPC/VPN peering attachment, the same attachment is charged once, however with TGW - TGW, seems that we may be charging the attachment twice (1 per TGW).

Accepted Answer

For Transit Gateway - Transit Gateway attachment pricing - I assume you are talking about TGW peering - This is charged to owners of each TGW. So there are two hourly charges.  TGW1 per hour charge and TGW2 per hour charge.

For more info, see this link https://aws.amazon.com/transit-gateway/pricing/ that has following included:
"For peering attachments, each Transit Gateway owner is billed hourly for the peering attachment with the other Transit Gateway."

You are right, VPN/VPC is charged once.

In addition to above there are data processing charges per GB of data processed.
