A Deep Dive into Azure Virtual Machines in China
Microsoft Azure, a leading cloud platform, offers its services in China through a partnership with 21Vianet. This arrangement creates a distinct Azure environment, often referred to as “Azure in China,” with its own infrastructure, operations, and agreements. Understanding the nuances of Azure VMs within this environment is crucial for organizations operating in the region. This guide provides comprehensive insights into Azure Virtual Machines in China, covering key aspects like technical features, pricing models, and the diverse VM types available.
Understanding Azure in China
Azure in China is a physically separate instance of Azure cloud services. It’s operated and managed by 21Vianet, ensuring data residency and compliance with local regulations. This separation means it differs from the global Azure offering in several key areas, impacting VM deployments and management. The primary point of contact for customers is 21Vianet, not Microsoft directly. This difference in operation is clearly outlined on learn.microsoft.com.
Key Technical Features and Differences
Several key technical aspects differentiate Azure VMs in China from the global Azure service. These differences primarily revolve around service availability and access to specific features. While Microsoft strives for feature parity, certain services might have limited functionality or be entirely unavailable in the China region. Details regarding service availability are regularly updated on learn.microsoft.com. Pricing is handled through www.azure.cn.

| F Series | Compute-optimized VMs with large local SSD temporary storage. | Batch processing, web servers, analytics, gaming |
| G Series | GPU-optimized VMs for graphics-intensive workloads. | Heavy graphics rendering, video editing |
| H Series | High-performance computing VMs designed for large-scale parallel computing. | HPC applications, fluid dynamics, financial modeling |
| L Series | High-throughput, low-latency VMs with direct-mapped NVMe local storage. | Big data, SQL, and NoSQL databases |
| M Series | Large-memory VMs with high core counts for large in-memory workloads. | Large in-memory databases, SAP HANA |
Pricing and Agreements
Pricing for Azure VMs in China is different from global Azure. It’s determined by factors like VM type, region, OS, and usage duration. Customers can choose between pay-as-you-go and pre-purchased options. The Compute Pre-Purchase (CPP) program offers significant discounts for longer-term commitments. Complete pricing details are available on www.azure.cn. Detailed information about different service level agreements (OSSA and OSPA) can be found on learn.microsoft.com.
Conclusion
Azure Virtual Machines in China provide a robust cloud computing solution tailored to the specific needs of the Chinese market. While some differences exist compared to the global Azure service, the platform offers a wide range of VM types to suit diverse workloads. Understanding these distinctions is crucial for successful cloud adoption in China.
FAQs
1. What are the key differences between Azure VMs in China and global Azure VMs?
The primary difference lies in data residency and operational control. Azure in China is operated by 21Vianet, ensuring data remains within the country. Service availability and specific features might also vary.
2. How is pricing for Azure VMs in China determined?
Pricing depends on VM type, region, operating system, and payment plan (pay-as-you-go or CPP). Detailed pricing is available on the Azure China website (www.azure.cn).
3. What is the Compute Pre-Purchase (CPP) program?
CPP is a pre-purchase program offering significant discounts on compute resources. It requires a longer-term commitment and is usually linked to a premium service agreement (OSPA) with 21Vianet.
4. Are there any limitations on connecting Azure in China to global Azure?
Azure China and global Azure regions are physically separate. Connectivity requires solutions like VPN site-to-site or ExpressRoute, connecting both environments through an on-premises network.
5. How can I get support for Azure VMs in China?
Support is provided by 21Vianet. Contact information and self-help resources are accessible through the Azure China support website (support.azure.cn).
