Costs

The management and routing simplification offered by the v2 (2023) architecture comes with a shift in costs seen by Cornell AWS accounts using Direct Connect, but the overall impact to Cornell AWS account costs are negligible.

V1 Architecture (pre-2023)

Cornell AWS accounts using Direct Connect saw these Direct Connect-related charges in the pre-2023 architecture:

• FREE
  • Bandwidth charges from traffic TO VPCs, FROM campus is free.
•  CUSTOMER
  • Bandwidth charges for traffic FROM VPCs TO campus using the Direct Connect is charged at $0.02/GB. This cost was born by each Cornell AWS account using Direct Connect in the pre-2023 architecture.

V2 Architecture (2023 and beyond)

Cornell AWS accounts using Direct Connect see these Direct Connect-related charges in the 2023 architecture:

• FREE
  • Bandwidth for traffic from the TGW to the VPC is free.
• Every VPC connected to the Transit Gateway is charged $0.05/hr by AWS. These charges will appear in customer AWS account invoices, but the charges will be paid for by CIT since a Cost Center tag on the TGW attachment automatically will automatically direct those charges to a CIT KFS account.
• Bandwidth charges for traffic from the VPC to the TGW is $0.02/GB. This cost is born by the customer and the magnitude of the charge will be similar to the Direct Connect egress charges born by the customer in the v1 architecture.
• Bandwidth for traffic from the TGW to the VPC is free.
