PolarDB:Billing method 3: subscription

Last Updated:May 20, 2024

If you want to use the subscription storage billing method for your cluster, you must purchase a specific amount of storage capacity when you purchase the cluster.

Scenarios

The total amount of data of the PolarDB clusters in specific regions within your Alibaba Cloud account is smaller than 10 TB, and the amount of data generated by your business seldom fluctuates.

Limits

  • The amount of storage capacity that you purchase applies only to a single cluster. This may cause resource waste, because the cluster may consume less storage capacity than the purchased amount.

  • After the purchased storage capacity is exhausted, your cluster can still be used as expected. The excess storage capacity is billed on a pay-as-you-go basis. If you purchase a storage plan, excess storage usage is counted against the available account in the storage plan first. After the storage plan is exhausted, you are charged on a pay-as-you-go basis. For example, you purchase 100 GB of storage space that uses the subscription billing method and a storage plan of 50 GB, but have 200 GB of data. For the 100 GB of data that exceeds the purchased storage capacity, 50 GB is deducted from the storage plan. The remaining 50 GB is billed on a pay-as-you-go basis.

Pricing

The purchased storage capacity is deducted based on storage usage.
