Part 2 of a sourced series. Every fact links to its source — company newsrooms, SEC filings, and reputable reporting. My opinions are marked. Nothing here alleges a crime; these are disclosure and segmentation choices, all legal. Corrections policy at the bottom; an evidence explorer lets you check every number.
For years, Azure had no number
Here's something strange about the second-largest cloud business on earth: until 2025, you couldn't find out how big it was.
On July 30, 2025, in its fiscal Q4 results, Microsoft disclosed a standalone annual revenue figure for Azure for the first time — Azure surpassed $75 billion in revenue, up 34% (Microsoft newsroom; Bloomberg).
First time. A $75-billion-a-year business, and that July was the first time investors saw the dollars.
A percentage is not a number
Before fiscal 2025, Microsoft reported Azure only as a year-over-year growth percentage — often in constant currency — and did not disclose Azure's absolute revenue in dollars. The segment's true size was left to analyst estimation (GeekWire; Data Center Dynamics).
Think about what "up 40%" tells you without a baseline. Forty percent of what? You can't value a business off a slope with no starting point.
Move the furniture, change the growth
What counts as "Azure" is itself a choice — and Microsoft changed it.
Effective with changes announced August 21, 2024, Microsoft moved Power BI per-user and Enterprise Mobility + Security revenue out of the closely watched "Azure and other cloud services" growth metric, into a new "Microsoft 365 Commercial" grouping — and added search and news advertising revenue into the Azure line (CNBC; SEC 8-K).
Microsoft framed it as better visibility into cloud consumption. Fair enough. But recast which products feed a headline growth number, and you've changed what that number means — and what it can be compared against.
"Commercial Cloud" was a run-rate, not a quarter
Before the Azure-dollar disclosure, Microsoft's go-to cloud headline was "Commercial Cloud." It sounded like a revenue line. It wasn't quite.
It was an annualized run-rate: revenue in the final month of the quarter, multiplied by twelve — bundling Office 365 Commercial, Azure, Dynamics Online, and other cloud properties. Microsoft later shifted to reporting quarterly Commercial Cloud revenue instead (Crunchbase News).
And that bundle reached across the org chart. The "Commercial Cloud" figure combined products drawn from two different official reporting divisions — Office 365 Commercial, Azure, and Dynamics — so the disclosed total did not reveal how much came from Azure infrastructure versus bundled productivity subscriptions (Fox Business).
So when "the cloud" grew, you couldn't tell whether the engine was infrastructure or Office seats.
What the critics said
Opinion — Michael. Some analysts argued that folding lower-margin productivity revenue into a single "cloud" run-rate flattered the apparent scale and growth of the business — and former CEO Steve Ballmer was reported to have criticized the opacity of the metric (Fox Business). I'd put it more plainly: when you get to draw the box, the box looks good. That's not a crime. It's an incentive. The cleanest disclosure rarely flatters the discloser, so don't expect the discloser to volunteer it.
Amazon and Google had to start somewhere too
Microsoft isn't unusual here. Every hyperscaler decided when to let the world see the cloud.
Amazon first broke out AWS as its own reportable segment in its Q1 2015 results (April 2015) — before that, AWS lived inside "Other." The breakout revealed AWS net sales of roughly $1.57 billion for the quarter, up about 49% year over year (Channel Futures; SEC 10-Q).
Alphabet first broke out Google Cloud as a separate reporting line with its Q4/FY2019 results (Feb 3, 2020), disclosing Google Cloud revenue of about $2.61 billion for the quarter and roughly $8.92 billion for full-year 2019 (CNBC; SEC 8-K).
A near-$9-billion business, disclosed for the first time only in 2020. The pattern repeats: the dollars arrive when the company decides they should.
And "Google Cloud" is two businesses in a trench coat
One more bundling note. Alphabet's Google Cloud segment, as defined in its filings, packages two distinct businesses — Google Cloud Platform (GCP) infrastructure and data analytics, and Google Workspace (formerly G Suite) collaboration subscriptions. The single "Google Cloud" figure mixes infrastructure (IaaS/PaaS) with productivity software (SaaS) (Computer Weekly; SEC 10-K).
Same move as Commercial Cloud: one tidy number, two very different economics underneath.
My read
Opinion — Michael. None of this is fraud, and I'm not alleging any. Companies are allowed to choose their segments, name their metrics, and decide when to break things out — and these choices are disclosed. My point is about what disclosure costs the audience: for years, the number that mattered most was the one you weren't given. A percentage with no baseline. A run-rate instead of a quarter. A bundle instead of a breakout. Each is legal and defensible on its own — and each happens to make the picture harder to second-guess. Bad systems, not bad people: the scoreboard rewards the flattering frame, so the flattering frame is what you get until someone decides otherwise.
Reject my read if you like. The framing choices are documented in the filings and coverage above — judge them yourself in the explorer.
