This topic describes the read-only instance types for RDS for MySQL Standard Edition (formerly X86) and their configurations.
To create an RDS for MySQL read-only instance, see Create an RDS for MySQL read-only instance.
RDS for MySQL read-only instances support the subscription and pay-as-you-go billing methods. For more information, see Read-only instance pricing. The price on the purchase page is final.
The maximum connections for an instance type refers to the maximum number of processes that can connect to an RDS for MySQL instance simultaneously.
General-purpose instance types do not guarantee maximum IOPS or maximum I/O bandwidth. If your business is sensitive to IOPS, choose dedicated instance types.
RDS for MySQL Basic series (with cloud disks)
Actual maximum I/O bandwidth of cloud disks: The actual bandwidth depends on the storage class, storage space, and instance type. For more information, see Throughput calculation formula.

RDS for MySQL high-availability series (with local SSDs)
If your RDS instance uses an instance type that provides 16 cores or more and you need a storage capacity of more than 8,000 GB, you can submit a ticket to apply for a quota. After your application is approved, the storage capacity of your RDS instance can reach up to 16,000 GB.
