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.

Data warehouse node

Changing the billing mode of node flavors:

  • You can change the billing mode of DWS cluster node flavors from pay-per-use to yearly/monthly to get a certain discount.
  • You can change the billing mode of DWS cluster node flavors from yearly/monthly to pay-per-use to use DWS resources more flexibly and save the costs of unnecessary resources.
NOTE:

Pay-per-use billing is only applied after the yearly/monthly subscription expires.

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).

Disk Storage

  • You can change the billing mode of DWS hot data storage from pay-per-use to yearly/monthly to get a certain discount.

Changing the billing mode of cold data storage:

  • You can change the billing mode of DWS cold data storage from pay-per-use to yearly/monthly to get a certain discount.
  • You can change the billing mode of DWS cold data storage from yearly/monthly to pay-per-use to use DWS resources more flexibly and save the costs of unnecessary resources.

EIP
  • A yearly/monthly EIP can be changed to a pay-per-use EIP billed by bandwidth after the yearly/monthly subscription ends.
  • A pay-per-use EIP billed by bandwidth can be changed to a yearly/monthly EIP.
  • Pay-per-use EIPs billed by bandwidth can be changed to pay-per-use EIPs billed by traffic, and pay-per-use EIPs billed by traffic can be changed to pay-per-use EIPs billed by bandwidth.

For details, see Table 1.

ELB
  • The billing periods of load balancers whose billing mode is changed to yearly/monthly in batches must be the same.
  • You can change the billing mode of a purchased dedicated load balancer from pay-per-use to yearly/monthly. Changing the billing mode from pay-per-use to yearly/monthly does not interrupt services.
