    ApsaraDB RDS:Billable items

    Last Updated:Oct 31, 2024

    The billable items that may be involved when you use ApsaraDB RDS include the billable items for ApsaraDB RDS instances, billable items for value-added features, and billable items for other cloud services related to ApsaraDB RDS. This topic describes the definitions, billing formulas, and billing methods of the billable items.

    RDS instances

    RDS instances can be classified into two types based on the billing methods of the RDS instances. For more information, see Billing methods.

    • Subscription or pay-as-you-go RDS instances. When you purchase a subscription or pay-as-you-go RDS instance, you must specify the computing resources and storage capacity for the RDS instance. After you purchase an RDS instance, you are charged for the instance type and storage capacity.

    • Serverless RDS instances. When you purchase a serverless RDS instance, you must specify the range of computing resources. The computing resources of the 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. After you purchase a serverless RDS instance, you are charged for the RDS Capacity Units (RCUs) and storage capacity.

    Instance type

    Category

    Description

    Definition

    Fees for the computing resources of your subscription or pay-as-you-go RDS instance. The RDS instance can be a regular instance , disaster recovery (DR) instance, or read-only instance. The name of the billable item is RDS instance type or instance type. The code of the billable item is rds_class or ClassCode.

    After you create an RDS instance, fees are generated for the billable item. If you increase the computing resources or the number of nodes, the fees for the billable item change.

    Billing formula

    • RDS Basic Edition and RDS High-availability Edition: Instance type fee = Unit price of the instance type × Duration

    • RDS Cluster Edition for ApsaraDB RDS for MySQL and ApsaraDB RDS for PostgreSQL: Instance type fee = Unit price of the instance type for a single node × Number of nodes × Duration

    • RDS Cluster Edition for ApsaraDB RDS for SQL Server: Instance type fee = Instance type fee for the primary RDS instance + Instance type fee for the read-only RDS instances

    Note

    The unit price of the instance type varies based on the region, database engine, and specifications. For more information, visit the ApsaraDB RDS buy page or check your bills.

    Billing method

    Subscription or pay-as-you-go.

    RCUs of serverless RDS instances

    Category

    Description

    Definition

    Fees for the computing resources of a serverless RDS instance. The name of the billable item is RCU. The code of the billable item is rds_serverless_rcu.

    After you create a serverless RDS instance, fees are generated for the billable item based on the actual usage of RCUs. If you suspend the serverless RDS instance, fees are no longer generated for the billable item.

    Billing formula

    • Serverless RDS instance that runs MySQL or PostgreSQL: RCU fee = Unit price of RCUs on a single node × Number of RCUs used by a single node × Number of nodes × Duration

    After you create an RDS instance, fees are generated for the billable item. If you expand or reduce the storage capacity of your RDS instance, the fees for the billable item change.

    Billing formula

    • Subscription or pay-as-you-go RDS instances on RDS Basic Edition and RDS High-availability Edition: Storage capacity fee = Unit price of the storage capacity for the instance × Storage capacity of the instance × Duration

    • Subscription or pay-as-you-go RDS instances on RDS Cluster Edition: Storage capacity fee = Unit price of the storage capacity for a single node × Storage capacity of a single node × Number of nodes × Duration

    • Serverless RDS instances that run MySQL or PostgreSQL: Storage capacity fee = Unit price of the storage capacity for a single node × Storage capacity of a single node × Number of nodes × Duration

    Note

    The unit price of the storage capacity varies based on the region, RDS edition, storage type, and billing method. The actual price in the ApsaraDB RDS console shall prevail.

    The duration in the preceding formulas is calculated in different methods based on the billing method of the instance.

    • Subscription instances: The duration indicates the subscription duration of the instances.

    • Pay-as-you-go or serverless instances: The duration indicates the billed duration of the instances in hours.

    Billing method
