Quick notes.

The comp is actually more like $20M/year if stock price doesn't tank.

Jassy started AWS (cloud compute side of AWS) with 60 folks or something way back.

He grew AWS to a very large size with very large margins (think $25B/year operating income? Maybe 50-60B in revenue? That is good particularly for Amazon which has had low margins elsewhere.)

AWS continues to compare well financial performance wise with competitors like google.

And folks are freaking out over $20M/year?

Amazons overall net sales are going to be in the 400 billion per year range. They can afford it.
