This topic provides an overview of instance types for YiTian primary ApsaraDB RDS for MySQL instances that originally use the ARM architecture. This overview includes the most recent instance types and the specifications for each instance type.
The YiTian product type is supported for RDS instances that run MySQL 8.0 and MySQL 5.7.
YiTian instance types for RDS High-availability Edition and RDS Cluster Edition are currently available in China (Hangzhou), China (Shanghai), China (Beijing), China (Zhangjiakou), China (Ulanqab), China (Shenzhen), China (Guangzhou), China (Chengdu), Indonesia (Jakarta), China (Hong Kong), and Singapore. More regions will be supported gradually. The regions displayed on the buy page prevail.
The instance types for YiTian RDS instances that run RDS Basic Edition are supported in specific regions. The regions displayed on the ApsaraDB RDS buy page prevail.
The instance types vary based on the region of your RDS instance. The instance types that are displayed on the ApsaraDB RDS buy page shall prevail.
The maximum number of connections in this topic indicates the maximum number of processes that can be connected to the RDS instance at a time.
General-purpose instance types cannot guarantee the maximum input/output operations per second (IOPS) and maximum I/O bandwidth. If your business is sensitive to IOPS, we recommend that you select dedicated instance types.
YiTian instance types for RDS High-availability Edition and RDS Cluster Edition support automatic storage scaling and automatic performance scaling. For more information, see Automatic storage expansion.
