Which Azure region type should a government agency use to meet strict isolation and compliance requirements?

Azure Government is designed specifically for US government agencies and their partners, offering a dedicated instance of Azure with enhanced security, compliance, and isolation features to meet stringent regulatory requirements. It operates physically and logically separate from Azure Global. Azure Global is the standard, worldwide Azure offering, not tailored for specific government compliance. Azure China is a separate instance of Azure operated by 21Vianet in China, primarily for Chinese customers. Azure Sovereign is a general term for cloud environments controlled by a specific nation, but Azure Government is the specific Microsoft offering for the US government's needs.
