This topic provides an overview of instance types for standard read-only ApsaraDB RDS for MySQL instances that originally use the x86 architecture, including the specifications for each instance type.
For more information about how to create a read-only ApsaraDB RDS for MySQL instance, see Create a read-only ApsaraDB RDS for MySQL instance.
Read-only ApsaraDB RDS for MySQL instances support two billing methods: subscription and pay-as-you-go. For more information, see Pricing of read-only instances. The actual prices on the buy page 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.
The maximum IOPS and maximum I/O bandwidth cannot be guaranteed for RDS instances that use general-purpose instance types. If your workloads are sensitive to IOPS, we recommend that you use dedicated instance types.
RDS instances on RDS Basic Edition (with cloud disks)
Actual maximum I/O bandwidth of cloud disks: This metric is affected by the storage type, storage space size, and instance type. For more information, see Formula for calculating the maximum throughput.

RDS instances on RDS High-availability Edition (with premium performance disks)
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.
