Contour vs F5 BIG-IP Container Ingress Services

Contour is a free, self-hosted, open-source Kubernetes ingress controller that provides the control plane for the Envoy edge and service proxy. It supports Kubernetes Ingress v1, its HTTPProxy custom resource and Gateway API. Contour updates ingress configuration dynamically with minimal dropped connections and supports multiple configuration types in clusters used by multiple teams. It can run as a Kubernetes deployment or daemonset, and administrators can delegate access to wildcard certificates. Documented security features include TLS termination, client authorization, rate limiting, JWT verification and IP filtering. Contour and Envoy expose metrics that Prometheus can scrape, and documentation includes guides for cert-manager, Gatekeeper and AWS Network Load Balancer. The project is tested with Kubernetes 1.21 and later and is intended for both cluster administrators and application developers. Community support is available through the project's GitHub page, where users can report issues or ask questions. Contour is a Cloud Native Computing Foundation incubating project; its documentation includes a threat model, a security reporting process and a security fix checklist.

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.
