Overview
Microsoft operates multiple Azure cloud environments to support a wide range of regulatory, security, and compliance needs. Two of the most important, and most commonly misunderstood, are Azure Commercial (Public) and Azure Government. While both environments are built on the same underlying Azure technology stack, they are designed for fundamentally different use cases, particularly when paired with Microsoft 365 offerings such as Commercial, GCC, GCC High, and DoD.
Azure Commercial, also referred to as global or public Azure, is Microsoft’s standard cloud platform used by enterprises worldwide. It offers the broadest service catalog, the fastest access to new features, and global regional availability. Both Microsoft 365 Commercial tenants and GCC (Government Community Cloud – Moderate) tenants rely on Azure Commercial as their underlying Azure platform.
Azure Government, by contrast, is a separate, sovereign cloud built exclusively for U.S. government agencies and their authorized partners. It operates in physically isolated U.S. datacenters, is managed by screened U.S. persons, and is authorized for high‑impact government workloads. This separation is not merely contractual or logical; it is enforced across the infrastructure, network, and identity layers.
Because of these enforced boundaries, Azure Government is the required Azure platform for organizations using Microsoft 365 GCC High or Microsoft 365 DoD. Both of these Microsoft 365 environments are paired with Microsoft Entra ID in Azure Government, ensuring identity, data residency, and access controls remain within the same sovereign cloud boundary.
