Microsoft develops and sells software, cloud services, and hardware. The company's core business consists of three primary product lines: Microsoft 365, Azure, and Windows. Microsoft 365 is a suite of productivity software, including Word, Excel, and Teams, sold through per-user subscriptions. Azure is a cloud computing platform providing on-demand compute, storage, and AI services. Azure operates on a consumption-based model where revenue grows as customers increase their usage of compute and storage. Windows is a PC operating system that Microsoft licenses to manufacturers. The company's strategy focuses on integrating generative AI across its products, specifically through Copilot assistants and the Azure AI Foundry platform. To support AI demand, Microsoft is expanding its global data center capacity and purchasing specialized hardware like GPUs. The business operates through three segments: Productivity and Business Processes, Intelligent Cloud, and More Personal Computing. Microsoft sells to large enterprises through a direct sales force and reaches smaller customers via a global partner network. A partnership with OpenAI provides Microsoft with exclusive rights to certain intellectual property and makes Azure the exclusive cloud provider for OpenAI's workloads. Microsoft is also transitioning its business model to include usage-based billing for AI agent workloads alongside traditional seat-based subscriptions.
