The management and routing simplification offered by the v2 architecture comes with a modest change in costs seen by Cornell AWS accounts using Direct Connect.

V1 Architecture

Cornell AWS accounts using Direct Connect will no longer see these charges:

  • Bandwidth charges for traffic from VPCs to campus using the Direct Connect is charged at $0.02/GB.
  • Bandwidth charges from traffic TO VPCs from campus is free.

V2 Architecture

These charges are new to Cornell AWS customers using Direct Connect:

  • Every VPC connected to the Transit Gateway will be charged $0.05/hr.
  • Bandwidth charges for traffic from the VPC to the TGW is $0.02/GB. 
  • Bandwidth for traffic from the TGW to the VPC is free.

Summary

In total, Cornell AWS accounts using Direct Connect should not experience any significant change in bandwidth-related charges for VPC traffic bound for the campus. But, these AWS accounts will see an increase in Direct Connect-related costs of about $36/mo for each VPC connected to the v2 Direct Connect architecture.
