AWS Drives More Than Half of Amazon’s Operating Income

(See Amazon Reports Q4 Sales Up 20% to $72.4B.)

That’s the same year-over-year growth rate (Q4 2018 over Q4 2017) for AWS that it saw in the year-ago quarter (Q4 2017 over Q4 2016). And AWS is the lion’s share of Amazon’s operating income: Nearly 58% in the fourth quarter of 2018, and nearly 59% for the full year. For the first quarter of 2019, Amazon anticipates net sales of $56 billion to $60 billion, up 10-18% year over year.
