Interconnect with China using Azure Virtual WAN and Secure Hub
When looking at common automotive, manufacturing, logistics industries, or other institutes like embassies, there is often the question about how to improve interconnection with China. Those improvements are mostly relevant for using Cloud Services like Microsoft 365, Azure Global Services, or interconnecting branches inside of China with a customer backbone.
In most cases, customers struggle with high latencies, low bandwidth, unstable connections, and high costs connecting to outside of China (for example, Europe or the United States). A significant reason for these struggles is the “Great Firewall of China,” which protects the Chinese part of the Internet and filters traffic to China. Nearly all traffic running from the People’s Republic of China to outside of China, except the special administrative zones like Hong Kong SAR and Macao SAR, passes through the Great Firewall.
Technical Features of Azure Virtual WAN
Azure Virtual WAN provides a unified networking service that simplifies the process of connecting branches, users, and applications. Below is a comparison of its key technical features:
| Feature | Description |
|---|---|
| Global Reach | Connects Azure regions globally, allowing for seamless data transfer. |
| Optimized Routing | Automatically selects the best path for data, reducing latency. |
| Integrated Security | Built-in security features, including Azure Firewall and VPN capabilities. |
| Scalability | Easily scales to accommodate growing network demands. |
| Centralized Management | Single pane of glass for managing network resources and configurations. |
Types of Connectivity Solutions
When interconnecting with China, various connectivity solutions can be utilized. Below is a comparison of the different types:
| Type | Description |
|---|---|
| MPLS/IPVPN Network | Provides a private network with guaranteed bandwidth and low latency. |
| SDWAN | Software-defined networking that optimizes traffic across multiple links. |
| Dedicated Internet Access | Direct access to the internet with a fixed bandwidth, suitable for cloud services. |
Challenges and Considerations
Connecting to Microsoft Cloud Services from China involves navigating several challenges. High latency and packet loss are common due to the Great Firewall’s filtering processes. Additionally, compliance with Chinese cybersecurity laws is crucial. Companies must partner with local ISPs that hold an ICP (Internet Content Provider) license to ensure legal compliance.
Key Providers
To establish a reliable connection, businesses often work with major providers such as:
– China Telecom Global Ltd.
– China Mobile Ltd.
– China Unicom Ltd.
– PCCW Global Ltd.
– Hong Kong Telecom Ltd.
These providers offer various services, including MPLS/IPVPN networks, SDWAN, and dedicated internet access, tailored to meet specific business needs.
Architecture and Traffic Flows
A compliant network architecture within China could look like the following example:
In this architecture, having an interconnect with the Microsoft Global Network in Hong Kong allows businesses to leverage Azure Virtual WAN Global Transit Architecture and additional services, such as Azure secure Virtual WAN hub, to consume services and interconnect to branches and data centers outside China.
Conclusion
Interconnecting with China using Azure Virtual WAN and Secure Hub is a complex but essential task for businesses looking to optimize their cloud services. By understanding the technical features, types of connectivity solutions, and challenges involved, organizations can make informed decisions that enhance their operational efficiency. As highlighted in various resources, including learn.microsoft.com and www.forbes.com, the right approach can significantly improve connectivity and compliance in the Chinese market.
