TencentDB data centers are hosted in multiple locations worldwide. These locations are known as regions. Each region contains multiple availability zones (AZs).
Each region is an independent geographic area with multiple isolated AZs. Separate AZs in the same region are connected via low-latency private networks. Tencent Cloud allows you to distribute Tencent Cloud resources across different locations. We recommend you place resources in different AZs to eliminate single points of failure which may lead to service unavailability.
Region name and AZ name can most directly embody the coverage of a data center. The following naming convention is used for your convenience:
region
indicates the geographic area that the data center covers, while the city
represents the city in or near which the data center is located.Tencent Cloud regions are completely isolated. This guarantees the maximum cross-region stability and fault tolerance. When you purchase Tencent Cloud services, we recommend you select the region closest to your end users to minimize access latency and improve download speed. Operations such as launching or viewing instances are performed at the region level.
Private network communication:
An availability zone (AZ) is a physical IDC of Tencent Cloud with independent power supply and network in the same region. It can ensure business stability, as failures (except for major disasters or power failures) in one AZ are isolated without affecting other AZs in the same region. By starting an instance in an independent AZ, users can protect their applications from being affected by a single point of failure.
When launching an instance, you can select any AZ in the specified region. For high reliability, you can adopt a cross-AZ deployment solution to ensure that the service remains available when an instance in a single location fails. Examples of such solutions include CLB and EIP.
The supported regions and AZs are as follows:
Note:Currently, public network access is supported only in the following regions:
Guangzhou, Shanghai, Nanjing, Beijing, Chengdu, Chongqing, Hong Kong (China), Singapore, Seoul, Tokyo, Silicon Valley, and Frankfurt.
