PolarDB:Billing method1: Bill by capacity (pay-as-you-go)

Last Updated:Jan 27, 2026

With the bill-by-capacity (pay-as-you-go) billing method, you do not need to specify a storage capacity at the time of purchase. Storage space automatically scales as your data grows, and you are charged hourly for the storage space that you use.

Scenarios

The total storage usage across all clusters in a specific region for an Alibaba Cloud account is low, and the workload fluctuates frequently.
