You can change the billing mode if it no longer meets your needs. Table 1 lists the changeable ECS billing items.

Only yearly/monthly and pay-per-use ECSs support billing mode changes. Spot ECSs do not support billing mode changes.

Change Description

Reference

ECS specifications (vCPUs and memory)

Changing the billing mode of an ECS includes the changes to compute resources (vCPUs and memory) and the system disk.

  • Change from pay-per-use to yearly/monthly to enjoy lower prices.
  • Change from yearly/monthly to pay-per-use to use the ECS more flexibly.
NOTE:

Changing from yearly/monthly to pay-per-use takes effect immediately.

EVS disk

Changing the billing mode independently from the ECS billing mode is not supported. You must attach an EVS disk to an ECS and initiate the change on the ECS side.

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.
