Azure revenue revealed: $33.2 billion, up 48% in one quarter

Microsoft disclosed Azure's quarterly revenue in dollars for the first time on Wednesday: $33.2 billion for the July–September quarter, up 48% from a year earlier. The company has never broken Azure out this way before, having historically shared only growth percentages or vague dollar milestones.

The timing matters. The disclosure lets investors line Azure up directly against Amazon Web Services and Google Cloud, whose parent companies already report cloud revenue in dollars every quarter. That comparison game just changed.

How does Azure stack up against Google Cloud?

Alphabet, which also reported earnings on Wednesday, said Google Cloud brought in $30.7 billion in the same quarter. That puts Azure slightly ahead — about $2.5 billion ahead, to translate the gap. But the growth picture is less flattering for Microsoft: Google Cloud, which also includes Workspace subscriptions, roughly doubled its revenue from a year earlier. That's about twice as fast as Azure's 48%, according to TechCrunch's calculations.

So Azure leads on size today. Google Cloud is closing the gap faster. Practitioners reading cloud strategy should note both numbers, because each tells a different story about where enterprise workloads are moving.

Azure beat expectations — and Microsoft's own forecast

Azure's revenue came in about $850 million above the $32.3 billion analysts expected. The 48% growth rate also topped the 44% to 45% that Microsoft CFO Amy Hood forecast on the company's July earnings call.

That's a double beat: against Wall Street and against the company's own guidance. Azure, where businesses rent computing power to run applications, SaaS, and to build and run AI models, is now Microsoft's largest and fastest-growing product line by the company's own figures. It accounted for roughly 36% of Microsoft's $92.3 billion in quarterly revenue — more than a third of the entire company flowing through one cloud platform.

What's this new "Agents and Infra" segment?

Microsoft also reshuffled its reporting structure this quarter. It replaced its previous three segments — Productivity and Business Processes, Intelligent Cloud, and More Personal Computing — with two new ones. Azure now sits inside Agents and Infra, one of the two new segments, alongside Microsoft 365's cloud business.

That combined segment brought in $76.8 billion, up 25% from a year earlier. In practical terms, Microsoft is now reporting its cloud infrastructure and its cloud productivity software as a single $76.8-billion-per-quarter engine — a bundle that dwarfs any competitor's comparable figure.

What does this change for the cloud race?

Amazon reports its earnings on Thursday, and analysts expect AWS to grow as well. AWS has been the largest cloud provider since the beginning, and nobody expects Microsoft to best it right now. But the competitive math is newly transparent: with all three major players reporting actual dollars, the race can be scored in hard revenue rather than growth-rate anecdotes.

For buyers and investors, that transparency cuts both ways. Microsoft has exposed Azure to direct quarterly comparison — a bet that the numbers will keep holding up against Amazon and Google. Wednesday's figures suggest they will, at least for now. Thursday's AWS report will show exactly how big the remaining gap is.
