Microsoft Azure
Cloud infrastructure, data and AI services, hybrid tools.
Overview
Azure is Microsoft’s cloud platform, generally available since 2010. Many large companies buy it alongside Microsoft 365 and Windows Server, which is why it is common in enterprises that already run Microsoft software.
Microsoft’s results for the quarter that ended September 30, 2026 list Azure revenue at $33,165 million, up 48%. Microsoft Cloud, a wider figure that adds Microsoft 365 and other subscriptions, was $63.9 billion, up 30%. This ranking uses the Azure line because it is the closest match to what the other companies report.
