RDS instances

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

Subscription or pay-as-you-go RDS instances: When you purchase this type of RDS instance, you must specify the specifications of the computing resources and storage. After the purchase, RDS instance type fees and storage fees are generated.
Serverless RDS instances: The computing resources of a serverless instance are automatically scaled based on workloads within the range that you specify, and the storage is automatically expanded based on the data volume. A serverless instance generates RCU fees and storage fees.

RDS instance type

Category	Description
Definition	The fee for the computing resource specifications of subscription or pay-as-you-go RDS instances, including regular instances, read-only instances, and disaster recovery instances. The billable item is RDS instance type (rds_class) or instance type (ClassCode). This billable item is generated after an instance is created. In most cases, the fee changes when the computing resource specifications of the instance increase or decrease.
Billing formula	Basic Edition and High-availability Edition: RDS instance type fee = Unit price of the RDS instance type * Duration Cluster Edition: RDS instance type fee = Instance type fee of the RDS primary instance + Instance type fee of the RDS read-only instances Note The unit price of an RDS instance type varies based on the region, database engine, and instance type size. For more information, see the buy page and your bills.
Billing method	Subscription or pay-as-you-go.
Deduction by savings plans or resource plans	Supported. Computing plans and general-purpose savings plans can be used to offset the pay-as-you-go RDS instance type fees.

RCU of serverless instances

Category	Description
Definition	The fee for the computing resources of serverless RDS instances. The billable item is RCU (rds_serverless_rcu). This billable item is generated after a serverless instance is created. You are charged based on the RCUs that you actually use. If you suspend the instance, billing for this item is also suspended.
Billing formula	RCU fee = RCU unit price * RCU usage * Usage duration Note For information about the RCU unit price, see SQL Server serverless pricing.
Billing method	Serverless.
Deduction by savings plans or resource plans	Supported. Elastic Savings Plan (Special Offer) and general-purpose savings plans can be used to offset the RCU fees of serverless RDS instances.

Storage

Category	Description
Definition	The fee for the storage of subscription or pay-as-you-go, or serverless RDS instances, including regular instances, read-only instances, and disaster recovery instances. The billable item is storage (rds_storage or Storage). This billable item is generated after an instance is created. The fee for this billable item changes when the storage capacity of the instance increases or decreases.
Billing formula	Storage fee = Instance storage unit price * Instance storage capacity * Duration Note The unit price of RDS storage varies based on the region, product edition, storage type, and billing method. The actual price that is displayed in the console prevails. The duration in the billing formula varies based on the billing method. Subscription instances: The duration is the subscription period that you purchase. Pay-as-you-go or serverless instances: The duration is the billing duration. The billing cycle is one hour.

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 the China (Shanghai) region, if the monthly fee is CNY 99, the month has 30 days, and you have used the service for 10 days, you will receive a refund of CNY 66 upon unsubscription.
- The character count in DAS Agent includes all characters in questions, answers, and O&M reports, such as Chinese characters, English letters, punctuation marks, line feeds, and other special characters. For example, the statement "DB instance rm-123 is healthy." contains 30 characters.
- 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 can be as short as "This instance has no exceptions in its current state," which contains 14 characters. 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 CNY 99 monthly fee covers approximately 15 to 50 diagnoses or reports, depending on the complexity of the Q&A. You can view the character usage of each historical conversation or O&M report on the DAS Agent details page.
Concurrency limit: The number of concurrent Q&A sessions that can run under your user ID (UID). DAS Agent generates O&M reports asynchronously during O&M windows, so these reports are not subject to the concurrency limit. As Model Studio and DAS Agent evolve, their tokens per minute (TPM), the time required for a diagnosis, and the response length may change. The concurrency limit may be adjusted in the future. Any such adjustments will be announced.

Audit and compliance

This scenario offers bank-grade security and compliance features that meet regulatory requirements in the Chinese mainland through transparent, long-term monitoring of database activities.

Assume your instance has a daily data ingestion of 1 GB. You set the SQL logs retention period to 180 days to meet compliance regulations in the Chinese mainland.

Note

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

You purchase a 100 GB storage disk for CNY 100/month.
With a daily data ingestion of 1 GB, the storage disk fills up after 100 days. From day 101, the system continues to write logs and bills you for the overage.
1. On day 101, a total of 101 GB of logs are stored. The pay-as-you-go fee for the 1 GB overage is 1 GB × CNY 0.048 = CNY 0.048.
2. On day 102, a total of 102 GB of logs are stored. The pay-as-you-go fee for the 2 GB overage is 2 GB × CNY 0.048 = CNY 0.096.
3. ... On day 180, a total of 180 GB of logs are stored. The pay-as-you-go fee for the 80 GB overage is 80 GB × CNY 0.048 = CNY 3.84.
4. After 180 days, older logs begin to expire and are purged. The storage usage stabilizes at 180 GB, and the daily pay-as-you-go fee for the 80 GB overage remains at CNY 3.84.
Because a 100 GB storage disk costs only CNY 100 per month, purchasing additional disk capacity is more cost-effective than paying overage fees. We recommend expanding your disk capacity in advance based on your usage forecast.
