The billable items for ApsaraDB RDS include RDS instance billable items, value-added service billable items, and billable items for other Alibaba Cloud services related to RDS. This topic describes the definitions, billing formulas, and billing methods of the billable items.
RDS instances
Based on the billing method, RDS instances can be classified into the following types:
Subscription or pay-as-you-go RDS instances. When you purchase such an RDS instance, you must specify the specifications of the computing resources and storage capacity. After you purchase the instance, you are charged RDS instance type fees and storage capacity fees.
Serverless instances. The computing resources of a serverless RDS instance are automatically scaled within the specified range based on your workloads. The storage capacity of the serverless RDS instance is automatically expanded based on the data volume. Serverless instances incur RCU fees and storage capacity fees.
