Ten years of the cloud wars, quarter by quarter

Operating margin

Google Cloud's climb from deep loss to profit.

What is and is not comparable here. AWS is a clean reportable segment, unchanged since 2015. The Azure lines are Microsoft's Intelligent Cloud segment — Microsoft has never disclosed quarterly absolute Azure revenue, so the growth chart uses Microsoft's own disclosed “Azure and other cloud services” YoY rate instead, and the dashed portion marks the FY25 segment re-definition at 2024Q3, which is not comparable with the solid line. Google Cloud includes Workspace; quarterly disclosure begins 2018Q4 and operating income 2019Q4, with the Apr-2023 recast applied to 2022. Market share, where shown, is an analyst estimate from Synergy and Canalys press releases rather than a filing. Every row in the dataset carries its own source URL.
