TencentDB for MySQL supports three types of architectures: single-node (cloud disk edition), two-node (formerly high availability edition), and three-node (formerly finance edition).
Note：The single-node architecture of cloud disk edition is currently supported in Shanghai, Chengdu, Guangzhou, Beijing, and Hong Kong (China) regions and will be available in more regions in the future.
Viewing the instance architecture
- For instances to be purchased, enter the TencentDB for MySQL purchase page, and select the architecture in the Architecture section.
- For purchased instances, log in to the TencentDB for MySQL console, find the target instance from the instance list, and view its architecture in the Configuration Info section.
