Microsoft

Microsoft operates primarily as a cloud-first organization running its internal and external services on Azure, backed by globally distributed, Microsoft-operated datacenters and a hybrid-cloud capable architecture.[1][4][6] Core business, productivity, and analytics workloads are delivered via Azure IaaS/PaaS (VMs, app services, databases) plus newer unified analytics platforms like Microsoft Fabric/OneLake, integrated with shared Microsoft services such as Microsoft 365 and identity.[1][5][7]
