What Should I Pay Attention to When Selecting RDS for MySQL Instance Specifications?

Specifications of associated RDS for MySQL instances should be greater than that of the DDM instance. Otherwise the performance will be affected.

Example:

Question: If a DDM instance has 8 vCPUs and 16 GB memory, which specification should I select for its associated RDS for MySQL instances? Should I use a primary/standby or single-node architecture?

Answer: According to best practices, the configuration ratio of DDM instances to RDS for MySQL instances should remain 1:2. If a DDM instance has 8 vCPUs and 16 GB memory, select at least two RDS for MySQL instances with 8 vCPUs and 16 GB memory. The number of required RDS for MySQL instances depends on your service requirements.

To run production workloads, select primary/standby RDS for MySQL instances to ensure high availability.
