F5 BIG-IP Container Ingress Services vs LiteSpeed Ingress Controller

F5 BIG-IP Container Ingress Services (CIS) connects Kubernetes and Red Hat OpenShift environments with F5 BIG-IP. It watches Kubernetes resources and adjusts BIG-IP configuration as applications change, while teams manage BIG-IP through Kubernetes or OpenShift command-line interfaces and APIs. CIS can send traffic from BIG-IP to clusters through NodePort or ClusterIP and supports F5 AS3 declarations. It provides HTTP and URI routing, load balancing, scaling, health monitoring, and Blue/Green or A/B traffic handling. F5 documents Ingress resources, OpenShift Routes, IngressLink coordination with NGINX Ingress Controller, and overlays including OpenShift SDN, Flannel, and Calico. BIG-IP data streams can export application and network statistics to tools such as Splunk. Installation is available through Helm or manual methods, with releases on Docker Hub and Red Hat Container Registry. The open-source plan is free, but requires a licensed BIG-IP system, a Kubernetes or OpenShift cluster, and AS3 installed on BIG-IP.

LiteSpeed Ingress Controller is the Kubernetes ingress component in LiteSpeed Web ADC, a software HTTP load balancer and application delivery controller. The solution can run on private dedicated hardware, hosted environments, or cloud infrastructure. The controller supports the Kubernetes Gateway API and installs through Helm, using native ingress without sidecars or Kubernetes modifications. It supports HTTP versions including HTTP/2 and HTTP/3. Built-in LiteSpeed Cache is intended to accelerate web applications, and its Web Application Firewall can use ModSecurity rules and templates. 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. Web ADC works with all web servers, though LiteSpeed Web Server is preferred for the backend. The default LoadBalancer installation exposes the service to the internet and load-balances all Ingress definitions; the documentation recommends Kubernetes cert-manager to manage TLS secrets for HTTPS. Helm installation includes full 24-7 support. Listed Web ADC plans are billed monthly: Small is $65 a month for one worker, Medium $130 a month for two workers, Large $260 a month for four workers, and Ultimate $520 a month with configurable workers.
