If the billing method for your Web Application Firewall (WAF) instance does not meet your business needs, you can switch it. To do so, you must unsubscribe from your current instance and purchase a new one. This topic describes how to switch the billing method.
Switching Between Billing Methods
WAF does not support switching billing methods directly. To switch the billing method, you must first unsubscribe from or shut down your current instance and then purchase a new one.
Unsubscribing from a subscription instance or shutting down a pay-as-you-go instance releases the instance. If your domain name is connected to WAF using a canonical name (CNAME) record, requests are still sent to WAF after the instance is released. These requests cannot be forwarded, which makes your website inaccessible. Before you unsubscribe from or shut down an instance, make sure that all web traffic is redirected from WAF to the origin server.
Switch from subscription to pay-as-you-go
1. Unsubscribe from a subscription instance
Contact your business manager or architect to unsubscribe from your instance. The instance must meet the following conditions:
The instance was purchased within the last five days.
The instance has not been used, which means no traffic has been generated.
2. Purchase a pay-as-you-go instance
Go to the Web Application Firewall 3.0 (Pay-as-you-go) buy page.
Set Billing Method to Pay-as-you-go and complete the configuration.
After you confirm the configurations, click Buy Now and complete the payment.
When you purchase a pay-as-you-go instance, you can also purchase a Security Capacity Unit (SeCU) resource plan to offset request processing fees and feature fees, which helps reduce your costs. For more information about SeCU resource plans and how to purchase them, see SeCU resource plans.
Switch from pay-as-you-go to subscription
1. Shut down a pay-as-you-go instance
Refunds are not applicable to pay-as-you-go instances. If you no longer use a pay-as-you-go WAF instance, you can shut it down at any time. After the pay-as-you-go WAF instance is shut down, billing for it stops.
To unsubscribe from an SeCU resource plan, contact your business manager or architect. The SeCU resource plan must meet the following conditions:
The SeCU resource plan was purchased within the last five days.
The SeCU resource plan has not been used.
2. Purchase a subscription instance
Navigate to the Web Application Firewall 3.0 (Subscription) buy page.
Set Billing Method to Subscription and configure the desired instance edition. For more information about the features of different pay-as-you-go and subscription instance editions, see Version Guide.
Click Buy Now and complete the payment.
