Microsoft Azure

Microsoft Azure holds 24% of the global cloud market and is growing faster than AWS, fueled by its exclusive access to OpenAI models through Azure OpenAI Service. Azure has over 60 data center regions globally — more than any competitor — and its enterprise relationships (1.4B Windows users, 300M Microsoft 365 subscribers) create unparalleled cross-sell opportunities. The Azure AI platform grew 60% year-over-year in fiscal 2025, contributing to Microsoft's Intelligent Cloud segment crossing $130B in annual revenue. Fortune 500 companies choose Azure over AWS at a 2:1 rate for new workloads due to its hybrid cloud integration with on-premises Active Directory and SQL Server environments.
