Introduction

If the current billing mode does not meet your requirements, you can change it without affecting your resources. If you also change the cluster specifications, the billing rules will be changed. For details, see Pricing of Changed Specifications. The following table lists the changeable DWS billing items.

  • You can change the billing mode of DWS cluster node flavors from pay-per-use to yearly/monthly to get a certain discount.

Snapshot storage space

DWS provides some free-of-charge storage for you to store the snapshot data. However, if you use more space than the free-of-charge storage space, the exceeded part is charged according to OBS billing rules. For details, see the OBS pricing details.

The free-of-charge space is the same as the size of the total storage space of a cluster (storage space of a single node x number of nodes).
