AWS offers a Data Egress Waiver that mostly eliminates Data Transfer charges for Cornell. See the AWS blog post about it for more details. The waiver applies to bandwidth charges for data sent out from AWS, but does not include CloudFront traffic out or Direct Connect traffic out.
Is egress from all AWS offerings covered by the waiver?
As of February 2018, most services that advertise the $0.09/GB data egress fee on the pricing page are covered. Feel free to check with the Cloud Team if you aren't sure about a particular service.
A One notable exception is CloudFront egress, which is not covered by the waiver. CloudFront egress shows as a separate line-item and is billed at a (slightly) cheaper rate than normal data egress. AWS is looking into adding CloudFront egress to the waiver. Any campus customers who have a current or future plan to generate significant CloudFront egress charges should forward their use-case to the Cloud Team for a consult with our AWS Representatives.
A second notable exception is Direct Connect egress, which is not covered by the waiver. Egress costs for our Direct Connect are $0.02/GB and those charges are billed to your AWS account.
According to AWS, their service offerings that use CloudFront under the covers, API Gateway for example, are covered by the egress waiver and a separate consult is not needed.
