This design improves compatibility and service performance.Ĭompared with standard ALB instances, WAF-enabled ALB instances are under enhanced protection. Listening and forwarding are performed by ALB so that request forwarding services and security services are decoupled from each other. WAF provides only security services and is decoupled from the forwarding services. WAF-enabled ALB instances are resistant to intrusions, provide more stable performance, and support higher security for services and data.ĪLB is integrated with WAF 3.0 at the service level. Benefits of WAF-enabled ALB instancesĪLB is deeply integrated with WAF 3.0, which provides one-stop security services that can detect malicious requests. This topic describes the benefits of WAF-enabled ALB instances and how to activate and manage WAF-enabled ALB instances. Forwarding services and security services are decoupled from each other to ensure compatibility and performance stability. Listening and forwarding are performed by ALB instead of WAF.
