Pricing of ApsaraDB RDS: billable items - ApsaraDB RDS - Alibaba Cloud Documentation Center

The billable items for ApsaraDB RDS include RDS instance fees, value-added service fees, and fees for other related Alibaba Cloud services. This topic describes the definitions, billing formulas, and billing methods for these items.

RDS instances

Based on the billing method, RDS instances are classified into two types:

Subscription or pay-as-you-go RDS instances: When you purchase this type of instance, you must specify the compute resources and storage capacity. After the purchase, you are charged for the RDS instance type and storage capacity.
Serverless instances automatically scale their compute resources within a specified range based on your workload and their storage capacity based on your data volume. You are charged for RCUs and storage capacity.

When you purchase a subscription or pay-as-you-go RDS instance, you must specify the compute resources and storage capacity. You are then billed for the RDS instance type and storage capacity.

RDS instance type

Category	Description
Definition	Fees for the compute resource specifications of subscription or pay-as-you-go RDS instances. This includes regular instances, read-only instances, disaster recovery instances.The billable item is named RDS Instance Type (rds_class) or Instance Type (ClassCode). After you create an instance, fees are generated for this billable item. An increase or decrease in the instance's compute resource specifications or number of nodes typically changes the fees for this item.
Billing formula	Basic Edition and High-availability Edition: RDS instance type fee = Unit price of the instance type × Duration Cluster Edition: RDS instance type fee = Unit price per node × Number of nodes × Duration Note The unit price of an RDS instance type varies by region, database engine, and specifications. Refer to the product page and your bills for details.
Billing method	Subscription or pay-as-you-go.

RCU for serverless instances

Category	Description
Definition	Fees for the compute resources of a serverless RDS instance. The billable item is named RCU (rds_serverless_rcu). After you create a serverless instance, fees are generated for this billable item based on the actual RCU usage. If you pause the instance, billing for this item also pauses.
Billing formula	RCU fee = Unit price per RCU on a single node × RCU usage on a single node × Number of nodes × Duration RCU fee = Unit price per RCU × RCU usage × Duration Note For RCU unit prices, see , Serverless ApsaraDB RDS for PostgreSQL fees, or .
Billing method	Serverless.

Storage capacity

Category	Description
Definition	Fees for the storage capacity of subscription, pay-as-you-go, or serverless RDS instances. This includes regular instances, read-only instances, and disaster recovery instances. The billable item is named Storage Capacity (rds_storage or Storage). After you create an instance, fees are generated for this billable item. An increase or decrease in the instance's storage capacity changes the fees for this item.
Billing formula	Subscription or pay-as-you-go Basic Edition and High-availability Edition instances: Storage capacity fee = Unit price of instance storage × Instance storage capacity × Duration Subscription or pay-as-you-go Cluster Edition instances: Storage capacity fee = Unit price of storage per node × Storage capacity per node × Number of nodes × Duration instances: Storage capacity fee = Unit price of storage per node × Storage capacity per node × Number of nodes × Duration Storage capacity fee = Unit price of instance storage × Instance storage capacity × Duration Note The unit price of RDS storage capacity varies by region, product series, storage type, and billing method. The price displayed in the console prevails. The duration in the formula varies based on the billing method. For subscription instances, the duration is the subscription duration. For pay-as-you-go or serverless instances, the duration is the billable hours. The billing cycle is 1 hour.
Billing method	Subscription, pay-as-you-go, and serverless.

Monthly fee for the Basic Edition
- The monthly fee includes a usage quota of 100,000 characters. Unused characters are cleared at the end of the month and cannot be rolled over to the next month or refunded.
- If you unsubscribe early, the monthly fee is refunded on a pro-rata basis, deducting the cost for the days the service was used. For example, in regions other than China (Shanghai), if the monthly fee is USD 30, the month has 30 days, and you have used the service for 10 days, you will receive a refund of USD 20 upon unsubscription.
- The character count in DAS Agent includes all characters in questions, answers, and O&M reports, such as letters, numbers, punctuation, spaces, and line feeds.
- To provide a "What You See Is What You Get" (WYSIWYG) experience, DAS Agent uses character-based billing instead of token-based metering. For example, when you ask if an instance is abnormal, DAS Agent may check multiple metrics, such as CPU utilization, I/O, queries per second (QPS), transactions per second (TPS), and memory. It may also review slow SQL lists, lock analysis results, and even security risk detection results. The agent's inference determines the specific checks performed, which typically cover these common issue types. This process can consume a large number of tokens. If an issue is found, the response can be thousands of characters long. If no issues are found, the response might be as short as "This instance has no exceptions in its current state." To provide a more intuitive understanding of usage, we bill by the number of characters in the Q&A. A typical Q&A session for SQL optimization or CPU utilization anomaly diagnosis consumes about 1,000 to 5,000 characters. An O&M report consumes about 5,000 characters. The Basic Edition monthly fee covers approximately 15 to 50 diagnoses or reports, depending on Q&A complexity. You can view the character usage of each historical conversation or O&M report on the DAS Agent details page.

Billing example

Audit Log (NoSQL Compatible) provides features such as log queries, online analysis, and data exports. It helps security auditors quickly detect unusual data operations and identify who made changes and when. It also helps business systems meet security and compliance requirements and assists developers and O&M engineers in troubleshooting performance issues.

Suppose your instance ingests 10 GB of log data daily. You set the Select the storage duration of SQL logs. to 180 days, enable log indexing, and configure a hot storage period of 7 days for performance troubleshooting.

Note

The SQL Log Storage Duration is the total retention period for your SQL logs, which are stored in cold storage by default.
To meet compliance regulations in the Chinese mainland, the cold storage period must be at least 180 days.

Feature	Billable item	Daily unit price	Daily usage	Daily fee
SQL logs	log traffic	USD 0.04/GB	10 GB	USD 0.4
SQL logs	cold storage	USD 0.001042/GB/hour	Day 1: 10 GB Day 2: 20 GB ... Day 173: 1,730 GB	10 * (180 - 7) * 0.001042 * 24 = USD 43.25

Note

The type of audit log records affects the volume of stored logs and their associated fees. You can customize the configuration after you enable this feature.

Enterprise Edition V3

Important
