Subscription is a billing method that requires you to pay for resources before you can use the resources. If your protection resource usage is relatively stable and predictable, or your web services require long-term protection, we recommend that you select the subscription billing method. This billing method provides lower prices than the pay-as-you-go billing method and can help reduce the cost of web application protection. This topic describes the billing rules of subscription Web Application Firewall (WAF) 3.0 instances.
Scenarios
The subscription billing method is more suitable than the pay-as-you-go billing method for the following scenarios:
Your protection resource usage is relatively stable and predictable:
If your protection resource usage is relatively stable and predictable, you can select the subscription billing method and purchase resources based on your business requirements to reduce costs.
If the number of queries per second (QPS) is relatively stable, you can select the subscription billing method and enable the burstable QPS (pay-as-you-go) value-added feature to reduce costs. If you enable the feature, requests that exceed the purchased QPS quota are billed on a pay-as-you-go basis. The following figure illustrates this billing scenario.
Your web services require long-term WAF protection: If your web services require long-term WAF protection, you can select the subscription billing method and select the WAF edition that best meets your business requirements to reduce costs.
Your web services belong to multiple accounts or your web services are added to WAF in hybrid cloud mode: Only subscription WAF instances that run Enterprise and Ultimate editions support the multi-account management feature and the hybrid cloud mode.
Billable items
The product and service prices may change. Refer to your Alibaba Cloud bill for the final amount.
If you enable WAF protection for an Application Load Balancer (ALB) instance, you are charged by WAF and ALB. For more information, see Activate and manage WAF-enabled ALB instances.
Major event protection fees
If you enable the major event protection feature, you are charged based on the subscription duration of the feature. The minimum subscription duration is 30 days. For more information about the major event protection feature and the fees for the feature, see Major event protection.
To enable the major event protection feature, perform the following steps: Log on to the WAF 3.0 console and select the resource group and region in which your WAF instance is deployed. In the left-side navigation pane, choose . On the Protection for Major Events page, enable the major event protection feature.
The major event protection feature takes effect immediately after you enable it. The validity period of the feature is the subscription duration that you specify when you enable the feature. After the validity period ends, the major event protection feature no longer protects your services.
Subscription WAF instance fees
If you purchase a subscription WAF instance, you are charged basic service fees and value-added service fees.
Basic service fees (required): fees for the edition, specifications, and subscription duration that you specify when you purchase the subscription WAF instance.
Value-added service fees (optional): fees for value-added features. You can enable one or more value-added features based on your business requirements. You must pay for value-added features before you can use the features. This does not apply to the burstable QPS (pay-as-you-go) and fraud detection features, which are billed on a pay-as-you-go basis.
The following figure shows the billable items.
If you purchase a subscription WAF instance and enable the major event protection, hybrid cloud protection, bot management for web application protection, bot management for app protection, or API security value-added feature, you cannot perform self-service unsubscription in the WAF console.

For more information about how to handle overdue payments, see Overdue payments.
Billing cycles
The billing cycle of a subscription resource corresponds to the subscription duration that you specify when you purchase the resource and is based on UTC+8 time. The start time of a billing cycle is the exact time when the resource is enabled or renewed, and the end time is at 00:00:00 on the next day of the expiration date. Both the start time and end time are accurate to seconds.
Bills for pay-as-you-go value-added features are generated and settled on a daily basis based on UTC+8 time. After a bill is settled, a new billing cycle begins.
The billing cycles of subscription resources are based on calendar years or months.
The billing cycle of the major event protection feature starts at the time when you enable the feature and ends at the time when the validity period elapses.
The bills for pay-as-you-go value-added features are generated and settled each day before 06:00. If you want to change instance configurations, we recommend that you perform the change after 06:00. Otherwise, the change is included in the bill of the previous day.
If the available balance in your account, including Alibaba Cloud account balance and vouchers, is less than the amount due for a pending bill, you are notified that your balance is low by text message or email.
Instance expiration
After your WAF instance expires, the instance no longer provides services. The following rules take effect:
You receive text message or email notifications 15 days, 7 days, 3 days, and 1 day before your WAF instance expires. The notifications remind you that the instance is about to expire and prompt you to renew the instance at the earliest opportunity.
If you do not renew the instance before the expiration date, the instance stops providing services upon expiration.
After your WAF instance expires, the instance enters a 15-day grace period. During the grace period, the configurations of the instance are retained.
If you renew the instance within the 15-day grace period, you can continue to use the configurations. Otherwise, the configurations are released and you must repurchase and reconfigure a new instance to continue protecting your web services.
If you do not renew a WAF instance before the expiration date, the instance may be suspended, and the system reminds or notifies you of the issue. If your web services require WAF protection, we recommend that you renew the instance at the earliest opportunity.
