What Are the Differences Between Yearly/Monthly and Pay-per-Use Payments?
A prepaid billing mode in which an ECS will be billed based on the service duration. This cost-effective mode is ideal when the duration of ECS usage is predictable.
A postpaid billing mode in which an ECS will be billed based on usage frequency and duration. The system generates bills every hour based on the actual usage and deducts fees from the account balance. A pay-per-use ECS can be provisioned and deleted at any time.
If a pay-per-use ECS is stopped and then restarted, the startup may fail due to insufficient resources. In such an event, wait several minutes before attempting another restart or change the ECS flavor.
Which One Is More Cost-Effective?
The yearly/monthly payment is more cost-effective than the pay-per-use payment in a certain period of time. Yearly/Monthly is ideal when the duration of ECS usage is predictable. Pay-per-use is ideal when you want more flexibility and control on ECS usage. Pay-per-use ECSs can be provisioned or deleted at any time. Select a billing mode based on the application scenario.
