Change Description

Reference

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.
  • If the specifications of a yearly/monthly resource do not meet your service requirements, you can change them on the cloud service console and pay for the new specifications. For details, see Pricing of a Changed Specification.

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

Changing the billing mode of hot data storage:

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

Cold storage

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.
