LiteSpeed Ingress Controller
What LiteSpeed Ingress Controller is
LiteSpeed Ingress Controller is the Kubernetes ingress component of LiteSpeed Web ADC, a software HTTP load balancer and application delivery controller. It supports the Kubernetes Gateway API and installs through Helm, using native ingress without sidecars or Kubernetes modifications. It handles HTTP versions including HTTP/3 and includes LiteSpeed Cache for web-application acceleration. Its Web Application Firewall can use ModSecurity rules and templates, while ZeroConf lets Kubernetes configuration changes take effect without restarting the load balancer. Realtime statistics and controller commands are available in the Web ADC WebAdmin Console. The software can run on private dedicated hardware, hosted environments, or cloud infrastructure, and Web ADC works with all web servers, though LiteSpeed Web Server is preferred for the backend. By default, installing the LoadBalancer exposes it to the internet and balances all Ingress definitions; the documentation recommends Kubernetes cert-manager for HTTPS TLS secrets. Helm installation includes full 24-7 support. Web ADC plans start at $65 a month, billed monthly; there is no free plan, but a free trial is available.
Who it suits
It suits teams operating Kubernetes ingress that want Gateway API support, caching, and ModSecurity-compatible firewall rules. The default internet exposure and broad Ingress handling are important to account for when deploying it.
What it does well
