What Are the Differences Between Yearly/Monthly and Pay-per-Use Billing?

The differences between yearly/monthly and pay-per-use billing are as follows:

• Yearly/Monthly: This is a prepaid billing mode suitable for predictable and long-term usage scenarios.
• Pay-per-use: This is a postpaid billing mode. You can create or delete resources at any time, and resources are billed by the second. The system generates billing records every hour based on the actual usage and deducts fees from your account balance.
