Cross-border connectivity
Network latency in China
In general, network latency between Azure China and Azure global regions is inevitable due to unpredictable network connections. For cross-border data transfers between Azure China and Azure global, latency is typically about three times higher than for data transfers within Azure global regions. It is a best practice to:
- Host the workload targeting Chinese users on Azure in China.
- Deploy the workload to the closest Azure region for users located outside of China.
Through VPN site-to-site or ExpressRoute
If you host your workload within China, please consider global connectivity and interoperability from a hybrid cloud scenario. For more information, see Cross-border connectivity and interoperability.
Azure Active Directory federation
Azure Active Directory (Azure AD) has features to support all common scenarios. The guides Authentication with on-premises Active Directory and Azure AD Connect show recommended ways and mechanisms for cloud authentication with on-premises Active Directory. It supports:
- Multi-national corporations that have multiple domains.
- Multi-national corporations that have a unified domain. Please note this solution doesn't support Dynamics 365 F&O Cross-Tenant integration services with Microsoft 365, Power BI, or Azure services.
Implementation and considerations
- Managing custom domain names in your Azure Active Directory
- Custom installation of Azure AD Connect
- Configuring federation with AD FS
Cross-border interoperability
Although Azure in China regions are disconnected from Azure global regions, you can still link between cross-border regions using one of the following solutions.
1. Connection via two individual ExpressRoute circuits
Linking across both infrastructure as a service (IaaS) and platform as a service (PaaS) is supported.
2. Connection via China Express model
This model only supports a link between infrastructure as a service (IaaS).
China Express provides a one-stop service for customers, requiring only one contract with the selected telecommunications operator, which reduces the business complexity.
3. Connection via VPN model
Linking across both infrastructure as a service (IaaS) and platform as a service (PaaS) is supported.
