The WAF QPS limit specification is typically for the entire instance, not for a single domain name. This means that the QPS (Queries Per Second) limit applies to the total number of requests the Web Application Firewall can handle across all domains configured within that instance.
For example, if a WAF instance has a QPS limit of 1000, this limit is shared among all the domains protected by that instance. If one domain receives 800 QPS, the remaining 200 QPS can be distributed among the other domains.
However, some advanced WAF solutions may offer the flexibility to set QPS limits on a per-domain basis for more granular control. This allows administrators to tailor the performance limits based on the specific needs and traffic patterns of each domain.
In the context of cloud services, platforms like Tencent Cloud offer WAF solutions that provide robust security features along with scalable performance. For instance, Tencent Cloud's Web Application Firewall service allows you to configure security rules and manage access control to protect your web applications from various attacks, while also offering capabilities to monitor and adjust performance settings based on your requirements.
