Can I Switch Between the WAF Cloud Mode and Dedicated Mode?

Direct switchover is not supported, but you can complete required configurations then use the WAF mode you want. When you add a domain name or IP address to WAF, you can select Cloud - CNAME, Cloud - Load balancer, or Dedicated for Protection. Once you select a WAF mode and connect the domain name to WAF, the WAF mode cannot be changed directly.

If you want to use another WAF mode for the domain name, deploy your services in the WAF mode you want first. Then, remove the domain name or IP address from the current WAF instance. After that, you can add the website in the mode you want to the WAF instance. For example, you are using a cloud WAF instance to protect domain name www.example.com. If you want to use a dedicated WAF instance to protect www.example.com, ensure that your current services are supported by WAF dedicated mode. Then, you can apply for a dedicated WAF instance and remove protected domain name www.example.com from the cloud WAF instance. Then, add www.example.com to the dedicated WAF instance.

When adding a website to WAF, you can select Cloud - CNAME, Cloud - Load balancer, or Dedicated for Protection. Before you start, get familiar with the following differences:

• Cloud - CNAME: protects your web applications that have domain name and are deployed on any clouds or in on-premises data centers.
• Cloud - Load balancer: protects your web applications that are deployed on Huawei Cloud and accessible over domain names or IP addresses.
• Dedicated: protects your web applications that are deployed on Huawei Cloud and accessible over domain names or IP addresses.
