Q1 earnings are in for the ?big three? cloud providers and you know what that means ? it?s time for an AWS vs Azure vs Google Cloud market share comparison. Let?s take a look at all three providers side-by-side to see where they stand.

Note: a version of this post was originally published in April 2018. It has been completely rewritten and updated for 2019.

AWS vs. Azure vs. Google Cloud Earnings

To get a sense of the AWS vs Azure vs Google Cloud market share breakdown, let?s take a look at what each cloud provider?s reports shared.


Amazon reported Amazon Web Services (AWS) sales of $7.7 billion, compared to $5.44 billion at this time last year. AWS revenue grew 41% in the first quarter ? at this time last year, that number was 49%.

Across the business, Amazon?s growth rates are slowing down ? which perhaps is all that can be expected at their mammoth size. However, their profit margins are increasing, giving investors a boon of $7.09 earnings per share compared to the projected $4.72.

AWS has been a huge contributor to this growth. This quarter, AWS revenue makes up 13% of total Amazon sales, up from 10% in the fourth quarter. AWS only continues to grow, and bolster the retail giant time after time.

In media commentary, AWS?s numbers seem to speak for themselves:

  • CNBC Markets: Amazon Web Services revenue grew 41% in the first quarter
  • Geekwire: AWS revenue approaches $8 billion in Q1, up 41 percent compared to last year


While Amazon breaks out revenue from AWS separately, Microsoft has a more nebulous ?commercial cloud business? ? which includes not only Azure, but Office 365, Dynamics 365, and other segments of the Productivity and Business Processes Division. This fact frustrates many pundits as it simply can?t be compared directly to AWS, and inevitably raises eyebrows about how Azure is really doing. Microsoft reported that the commercial cloud business grew 41% in the first three months of 2019, to $9.6 billion.

What Microsoft reported for Azure specifically is the growth rate: 73%. However, Microsoft did not specify what that growth actually represents. This time last year, the Azure growth rate was reported at 93%. Supposedly, analysts say that Azure is growing at a faster rate than AWS was at a similar size, but without specific numbers, it?s hard to say what this actually means.

Here are a few headlines on Microsoft?s reporting that caught our attention:

  • GeekWire: Azure revenue remains a mystery, but cloud services continue to drive Microsoft forward
  • The Motley Fool: Is Microsoft Becoming a Better Cloud Stock Than Amazon?
  • TechRepublic: Microsoft keeps hiding Azure revenue numbers, but why?

Google Cloud

Like Microsoft, Google avoided reporting specific revenue numbers for its cloud business yet again. Parent company Alphabet reported $36.34 billion in revenue for the quarter, up 17% from $31.15 billion for the same quarter last year. Google Cloud Platform revenue is included in Google?s ?other? revenue category, alongside G Suite, Google Play, and hardware such as Nest. That category reported revenue of $5.45 billion for the quarter, up 25% from the same quarter last year when it was $4.25 billion.

According to Google and Alphabet CFO Ruth Porat, ?Google Cloud Platform remains one of the fastest growing businesses in Alphabet with strong customer momentum reflected in particular in demand for our compute and data analytics products?. But without specifics, it?s hard to say what this means.

2018 vs. 2019 Market Share

When we originally published this blog last year, we included a market share breakdown from analyst Canalys, which reported AWS in the lead owning about a third of the market, Microsoft in second with about 15 percent, and Google sitting around 5 percent.

This year they report an overall growth in the cloud infrastructure market of 42%. By provider, AWS had the biggest sales gain with a $2.3 billion YOY increase, but Canalys reports Azure and Google Cloud with bigger percentage increases.

AWS vs Azure vs Google Cloud Market Share ? And the winner is:

Ultimately, it seems clear that in the case of AWS vs Azure vs Google Cloud market share ? AWS still has the lead.

Bezos has said, ?AWS had the unusual advantage of a seven-year head start before facing like-minded competition. As a result, the AWS services are by far the most evolved and most functionality-rich.?

Our anecdotal experience talking to cloud customers often finds that true, and it says something that Microsoft and Google aren?t breaking down their cloud numbers just yet.

Others have made their own estimates. In November, a Goldman Sachs report stated that AWS, Azure, Google Cloud, and Alibaba Cloud made up 56% of the total cloud market, with that projected to grow to 84% this year. The report shows AWS far, far in the lead with 47% of the market projected for this year, with Azure and Google trailing at 22% and 8% market share, respectively.

AWS remains far in the lead for now. With that said, it will be interesting to see how the actual numbers play out, especially as Google positions itself for multi-cloud and Azure continues rapid growth rates. Perhaps this time next year will report revenue numbers broken out and we?ll be able to say for sure.
