Billing method

OSS accelerator (AcceleratorCacheSize)

You are charged based on the provisioned capacity of the OSS accelerator and the duration of usage.

Important

When using this feature, you are charged based on the capacity of the accelerator that you request, regardless of the actual volume of data stored.

For example, if you provision 100 GB of accelerator capacity and prefetch 50 GB of data, you are still charged for the full 100 GB provisioned capacity.

Bills are generated on an hourly basis (generally after a billing cycle ends). The time when bills are generated is determined by the system.

  • Pay-as-you-go: Accelerator charges = Provisioned capacity × Duration of usage × Unit price per GB

  • Resource plans are not available.
