Considering that Oracle database is extremely pricey and priced per CPU core, I think Amazon could make a substantial savings here.
Edit: I am having too much fun here. Note that I’m pretty sure Amazon gets a steep discount so there’s no way they are paying the following amount.
This is Oracle multi core pricing: www.oracle.com/us/corporate/press/017192_EN. And oh, they charged by the soft core (CPU thread), not full physical core.
From the example: 0.75 * 8 [cores] *$40,000 = $240,000.
Now, let’s play with the number. It’s very believable for amazon.com database to be running on > 10,000 bare metal servers. Let’s pretend that each server runs 30 cores. That makes the math: 0.75 * 30 * 10,000 *$40,000 = $9,000,000,000.
