Changing the Cloud WAF Edition and Specifications

You can change the edition of your cloud instance to a higher or lower edition. Beyond that, you can subscribe to more or unsubscribe from some domain name, QPS, and rule expansion packages without changing the WAF edition you are using.

Prerequisites

You have obtained management console login credentials for an account with the WAF Administrator and BSS Administrator permissions.
You have purchased a cloud WAF instance.

Specification Limitations

Changing specifications does not change the billing mode or expiration date.
A domain package allows you to add 10 domain names to WAF, including one top-level domain and nine subdomains or wildcard domains related to the top-level domain.
The QPS limit and bandwidth limit of a QPS expansion package:
- For web applications deployed on Huawei Cloud
  Service bandwidth: 50 Mbit/s
  
  QPS: 1,000 (Each HTTP GET request is a query.)
- For web applications not deployed on Huawei Cloud
  Service bandwidth: 20 Mbit/s
  
  QPS: 1,000 (Each HTTP GET request is a query.)
A rule expansion package allows you to configure up to 10 IP address blacklist and whitelist rules.

Constraints

Specifications of an expired WAF instance cannot be changed. To do that, renew the WAF instance first.
Changing WAF editions or specifications is not supported if you have used some functions of the WAF edition, or you have no extra domain name, QPS, or IP blacklist and whitelist rules to unsubscribe from.

Application Scenarios

Scenario 1: If the current cloud WAF edition does not support some functions, or cannot meet your protection requirements for domain names, QPS, or IP address blacklist and whitelist rules, you can use this function to upgrade service specifications. For details about WAF editions, see Edition Differences.
Scenario 2: If the WAF edition you are using has much more protection capabilities or domain name, QPS, and rule expansion packages than what you actually need, you can change the WAF edition to a lower one or unsubscribe from some packages.

Impact on the System

Changing a WAF edition or quantity of domain, QPS, or rule expansion packages has no impact on protected website services.
