Pay-per-Use Billing

Concept

Pay-per-use billing is a postpaid billing mode in which an ECS will be billed based on usage frequency and duration. ECSs are billed by second. The system generates a bill every hour based on the usage duration and deducts the billed amount from the account balance. A pay-per-use ECS can be provisioned and deleted at any time.

For more billing information, see Pay-per-Use Billing.

For a stopped pay-per-use ECS, the startup may fail due to insufficient resources. Please wait for several minutes before attempting another restart or changing the ECS specifications.

Billing Examples

In the pay-per-use billing mode, ECSs are billed by the second. The price per second of each type of ECS can be obtained by dividing their hourly price by 3600. Obtain the hourly price on the Product Pricing Details page.

For example, if you purchase a pay-per-use ECS priced $0.68 USD/hour, the ECS will be billed based on the usage duration by the second.
  • If you use the ECS for 30 minutes, you need to pay for $0.34 USD (0.68/3600 x 30 x 60).
  • If you use the ECS for 1 hour and 30 minutes, you need to pay for $1.02 USD (0.68/3600 x 90 x 60).
