Q1/16 revenue at Amazon was a staggering $29 billion and net income was $513 million. More interesting, Amazon Web Services (AWS) revenue jumped 64% to $2.6 billion, 9% of total revenue, but 67% of operating income and 56% of operating profits (the amount of revenue that remains after accounting for variable expenses and fixed operating expenses). Amazon is essentially a very profitable web services firm that happens to sell things.
