Web Application Firewall (WAF) 3.0 supports the subscription and pay-as-you-go billing methods. The subscription billing method is more suitable for budget-conscious customers, customers whose resource usage remains relatively flat, and customers who require resources for long-term use. The pay-as-you-go billing method is more suitable for customers who require resources for short-term use. This topic describes the scenarios, billable items, billing cycles, and activation methods of subscription and pay-as-you-go WAF instances.
WAF 3.0 instances do not support switching between different billing methods.

Billing cycle | The billing cycle of a subscription WAF instance is the subscription duration of the WAF instance, which is the subscription duration that you specify when you purchase the WAF instance. | The fees of a pay-as-you-go WAF instance are generated on a daily basis (UTC+8). After fees are calculated, a new billing cycle begins. |
