What is the best way to test load and pricing like this? In my mind, the way I would do it is run the server and then hit it with a load tester (i.e. a number of queries simulating the number of users desired). That will tell us if it can withstand the load. Then I would seeing how much it costs after 5 minutes of this test, and then multiply that by 7200. It just feels kind of primitive and naive. There must be a better way. For example, Google can't simulate real-world service loads like this, so there must be.
