PolarDB for PostgreSQL Standard Edition uses a shared storage architecture and stores data in ESSDs. You are charged for the storage capacity of the ESSDs that you purchase. PolarDB for MySQL Standard Edition supports the following billing methods: pay-as-you-go + storage plan, pay-as-you-go, and subscription. The storage price varies based on the billing method that you use.
Pay-as-you-go + storage plans (recommended)
If you use the pay-as-you-go + storage plans billing method, the storage usage is first offset by the storage capacity of the storage plans that you purchase. After your storage plans are exhausted, you are charged for the excess storage usage on a pay-as-you-go basis.
Storage plans can be used only on clusters that use the pay-as-you-go billing method for storage, and cannot be used on clusters that use the subscription billing method for storage.
Storage plans can be used to offset the storage usage based on specific offset factors. The following table describes the offset rules.

Pay-as-you-go
If you use the pay-as-you-go billing method, you are charged for the storage capacity (measured in GB) of the ESSDs that you purchase on an hourly basis. The price varies based on the type and storage capacity of the ESSDs that you select when you purchase the cluster. The price also varies based on the region in which the cluster is deployed.
