AWS Tops Earnings Estimates in Third Quarter reported its third quarter earnings on Thursday and, as expected, its massive cloud business was the standout performer.

Amazon Web Services (AWS) just beat Wall Street estimates for the period, raking in about $4.6 billion in revenue. That's up by 42% year over year, and by nearly 12% from the previous quarter, when it earned $4.1 billion.

Operating income for the quarter-ended Sept. 30 was also higher than expected at $1.2 billion, up by 38% year over year.

AWS was once again its parent company's fastest-growing business, outpacing the year-over-year growth of the North America (35%) and International (29%) retail units. AWS comprised 11% of's total earnings for Q3.

Meanwhile, cloud rival Microsoft reported a 90% year-over-year growth for its Azure cloud platform in its own earnings report on Thursday.

Nevertheless, AWS' run rate of $18 billion is nothing to sniff at. Executives pointed to several milestones over the past quarter as drivers of its growth, including:
