AWS - Pricing, Billing FAQ
UW-Madison AWS cost structure:
Updated March 1, 2019 at completion of pilot. See AWS - Service Description
The net cost to campus customers will be equal to Amazon's published rates for AWS, but will include a 15% network egress waiver:
- Amazon's current rates for individual AWS services can be found on Amazon's Cloud Services Pricing page
- 15% network egress waiver
- If network charges (Data Transfer Out to the Internet) do not exceed 15% of a customer's monthly bill then they will be waived.
- Example 1: If a customer's total monthly fees would have been $1000, but $50 of those fees were network egress, the customer's final bill would be $950, as all network egress fees would be waived.
- Example 2: If a customer's total monthly fees would have been $1000, but $150 of those fees were network egress, the customer's final bill would be $850, as all network egress fees would be waived.
- Example 3: If a customer's total monthly fees would have been $1000, but $250 of those fees were network egress, the customer's final bill would be $850, as only $150 of network egress fees would be waived.
- To be eligible for the waiver, an account must meet some basic requirements such as primarily using the Internet2 Network for connectivity. The account also cannot be used for specifically bandwidth intensive applications (e.g., media streaming or MOOCs).
- Accounts that have opted in to Business Level Support, have a support charge based on 10% of Amazon retail spend
- DLT, the campus reseller for AWS, discounts AWS pricing 5% as part of the Internet2 agreement with Amazon. UW-Madison Public Cloud applies a 5% overhead surcharge to the DLT rate (excluding any DLT Support charges) to recover a portion of its costs, including security & monitoring tooling provided to all accounts. The net cost to campus customers will be equal to Amazon's published rates for AWS, but will include a 15% network egress waiver.
- The 5% surcharge is currently an estimated rate. Data will be collected on this charge this fiscal year and may be adjusted up or down in the future based on actual costs.
UW-Madison AWS accounts are not eligible for the AWS Free Tier.
Customers are responsible for ensuring that any grant funds used to pay for AWS is done in accordance with RSP (https://rsp.wisc.edu) policy and federal requirements (2 CFR 200 Subpart E). Basic guidance can be found at https://www.rsp.wisc.edu/awardmgt/explanation_costs.html. It is recommended that all customers who wish to use a grant to pay for AWS contact RSP for guidance.
Customers can elect to receive a billing alert using CloudWatch whenever their monthly spend reaches a specified maximum value. Please note that CloudWatch billing alarms only provide a rough estimate of current monthly spend. They do not represent actual spend at any given point in time and numbers may be skewed due to reserved instance usage and service credits/grants applied to any account. To update the value associated with your account's billing alarms, email firstname.lastname@example.org.
DLT bills UW-Madison at the end of the month following a billing cycle, however, campus customers won't receive a bill until the end of the following month (e.g., August charges won't be billed to a customer until October).
