Amazon, Inc.'s AWS Is Crushing It -- and It Has More Room to Run

If you thought e-commerce sales account for the bulk of's (NASDAQ: AMZN) business, you'd be right. But if you thought e-commerce sales represented the biggest portion of the company's operating profits, you'd be way off base. As it turns out, Amazon's global e-commerce business only accounts for approximately 25% of operating profits. It's the company's cloud-computing services, called Amazon Web Services (AWS), that is driving most of Amazon's profits.

What is AWS?

If you're unfamiliar with AWS, it offers a range of pay-as-you-use cloud-computing services including database storage, applications platforms, and other IT resources. It owns and maintains the network-connected servers used for these application services as customers access them through web applications.

And AWS isn't just another cloud-computing platform in a crowded space. AWS absolutely dominates the cloud services market. In fact, Amazon's cloud is 10 times larger than the next 14 competitors combined, according to a Gartner report.

Highlighting the sort of caliber attracted to AWS, Amazon's diversified mix of commercial customers includes giants like Netflix, General Electric, Intuit, and Comcast.

Mind-boggling growth

But what's perhaps even more impressive than the scope of AWS is the significant growth in operating profits it has contributed to Amazon's business.

In Amazon's most recent quarter, AWS generated $861 million of operating income on $3.231 billion in net sales. AWS' $861 million in operating income was up a whopping 102% compared to the segment's $428 million operating profit in the year-ago quarter. Further illustrating the segment's strong growth recently, AWS' operating profits in the nine months ending Sept. 30, 2016, were $2.182 billion, up from $927 million in the same period in 2015.

What about rising competition?

Going forward, there may be some concern among investors about AWS' competitive position as deeper-pocketed competitors like Alphabet and Microsoft step up their cloud-computing offerings. But Amazon CFO Brian Olsavsky isn't concerned. When asked specifically about Alphabet's reinvigorated efforts in the space during Amazon's most recent earnings call, Olsavsky responded (via a Reuters transcript) by citing the compelling reasons customers continue to choose AWS, and how the cloud-computing market won't be a zero-sum competitive environment:

Considering how sharply AWS' business is growing recently, there's no reason to expect AWS growth to come down significantly anytime soon. Sure, growth will likely decelerate -- and possibly even temporarily stall in some quarters impacted by heavy investments and big expansions. But as Amazon's CFO emphasized in the company's most recent earnings call, the reasons customers have been choosing AWS aren't disappearing anytime soon. Further, even if customers' reasons for choosing AWS over competitors in the future become less compelling, there's plenty of room for competition in this fast-growing industry.
