Billing Examples
Suppose you enable NAT Firewall elastic protection at 12:00 on a certain day. On that day, the traffic of this NAT Firewall Instance is 550M, the instance bandwidth specification is 500M, and the elasticity cost for that day is (550-500) × 2.41 × (24 - 12)/24 = 60.25 USD.
Suppose you enable pay-as-you-go storage for Log analysis at 00:00 on a certain day. Your Log storage specification is 1500GB. On that day, you generate 36GB of new logs, then the cost for that day is 1536 × 0.006 = 9.216 USD.
Suppose you enable VPC Firewall elastic protection at 06:00 on a certain day. On that day, the traffic of this VPC Firewall instance is 1000M, the instance bandwidth specification is 800M, and the elasticity cost for that day is (1000-800) × 0.09 × (24 - 6)/24 = 13.5 USD.
Billing Process
1. Top up your account first to ensure the balance exceeds the pre-frozen amount. After the top-up is completed, pay-as-you-go services can be activated normally.
2. After a pay-as-you-go product is activated and purchased, the system initiates pay-as-you-go billing. Common billing cycles include: hour, day, and month.
3. After activation, the system estimates the frozen amount based on the product's settlement cycle and historical usage, and freezes the balance.
4. Unfreeze: On the settlement date (or time), the system will unfreeze the frozen amount for the device, release it to the available balance, and then proceed with settlement.
5. When the billing reaches the settlement cycle, the system performs rate calculation and deduction based on usage and unit price, then generates the bill.
6. When your account is overdue, the elastic features of NAT and VPC Firewall will be disabled. If your CFW main package is still valid, NAT and VPC Firewall will continue to provide protection based on instance specifications.
