The storage capacity of PolarDB is automatically scaled up or down based on the amount of the stored data. You do not need to manually configure the storage capacity. You need only to pay for the storage space that you use. We recommend that you purchase PolarDB storage packages if you need to store large amounts of data.

Prices of storage packages and discounts

If you need to store large amounts of data, for example, 1,000 GB data or more, storage packages are more cost-effective than the pay-as-you-go billing method. Larger discounts are provided for the storage packages that have higher storage capacities.

Considerations

  • You can purchase only one storage package of each type.
  • You are charged for the extra storage capacity that is not covered by the storage package on a pay-as-you-go basis. Assume that you have three PolarDB clusters and each of the clusters requires 400 GB of storage capacity. If you purchase a storage package of 1,000 GB and the three clusters share the storage package, you are charged for the extra 200 GB storage capacity on a pay-as-you-go basis.
Note For more information about storage packages, see FAQ.
