Appendix: Example DevPay Activity Pages

This appendix walks through a simple example in which you create an imaginary DevPay product to see what the numbers look like on the DevPay Activity page and in the DevPay transaction history over a period of a few months. The goal is to familiarize you with the pages and help you understand the billing, collection, and revenue reporting process DevPay uses. The example covers multiple months because:

  • The billing and collection cycle for a single month's revenue spans two months

  • We want to show the DevPay Activity page during a month when you have both existing customers and new ones signing up

In this example, you create a paid AMI called ABC AMI. You begin selling ABC AMI in June 2009. The following table shows the price you charge and the corresponding AWS cost.

Note

The Amazon EC2 prices shown here were valid when this document was originally written. The prices might have changed since then. For the current Amazon EC2 prices, go to the Amazon EC2 product page.

Note that you don't charge customers for data transfer in and out. It's an unusual pricing scheme, but we've chosen it to shorten and simplify the example. Also, to keep the example short, we're ignoring any other instance types and EC2 features (like high-CPU instances, regional data transfer, Elastic Block Store, etc.). For the full list of usage-based costs for Amazon EC2, see Allowed Usage-Based Charges.

The following sections show the activity for your products over a period of three months:
