ApsaraDB for SelectDB charges for three independent resources: compute, cache, and storage. Compute and cache support subscription and pay-as-you-go billing. Storage is always pay-as-you-go.
Both inbound and outbound Internet traffic are free of charge when you connect to an instance through a public endpoint. For more information, see Request and release a public endpoint.
Billable items
Billable item | Billing method | Billing formula |
Compute resources | Subscription, Pay-as-you-go | Unit price × Number of CCUs × Duration |
Cache | Subscription, Pay-as-you-go | Unit price × Cache size (GB) × Duration |
Storage resources | Pay-as-you-go only | Unit price × Storage size (GB) × Duration |
Compute resources
A Compute Capacity Unit (CCU) is the billing unit for compute resources. One CCU equals 1 vCPU and 4 GB of memory. Instance performance scales linearly with the number of CCUs. The compute resource specification must be an integer multiple of 1 CCU.

Cache
The cache stores hot data to accelerate read and write operations. Available cache sizes depend on the selected compute resource specification.

Storage resources
Storage resources hold your full dataset. Billing is pay-as-you-go, charged hourly based on actual usage.
Tip: A storage plan can reduce storage costs by approximately 45%. If your storage usage is predictable, purchase a storage plan to offset pay-as-you-go charges.

Billing examples
Subscription
Assume that you purchase a subscription instance in the Singapore region with 4 vCPUs and 16 GB of memory (4 CCUs) and 200 GB of cache. The subscription duration is one month. During this month, assume the instance stores an average of 500 GB of data. The total fee for the instance for one month is USD 192.00. The cost breakdown is as follows:
Compute resource fee: USD 36.980/CCU/month × 4 CCUs × 1 month = USD 147.92.
Cache fee: USD 0.152/GB/month × 200 GB × 1 month = USD 30.40.
Storage resource fee: USD 0.000038/GB/hour × 500 GB × 30 days × 24 hours = USD 13.68.
Pay-as-you-go
Assume that you purchase a pay-as-you-go instance in the Singapore region with 4 vCPUs and 16 GB of memory (4 CCUs) and 200 GB of cache. You use the instance for one hour. During this hour, assume the instance stores an average of 500 GB of data. The total fee for the instance for one hour is USD 0.347. The cost breakdown is as follows:
Compute resource fee: USD 0.069170/CCU/hour × 4 CCUs × 1 hour = USD 0.277.
Cache fee: USD 0.000253/GB/hour × 200 GB × 1 hour = USD 0.051.
Storage resource fee: USD 0.000038/GB/hour × 500 GB × 1 hour = USD 0.019.
