What Ingress controllers have you already encountered in your practice?

Ingress controllers are components of Kubernetes that manage incoming HTTP/HTTPS traffic into the cluster.

Commonly encountered Ingress controllers include:

• NGINX Ingress Controller — the most popular, flexible, and widely used.
• Traefik — a modern controller with support for dynamic configuration and service integration.
• HAProxy Ingress — based on HAProxy, suitable for high-load systems.
• Istio Ingress Gateway — part of the Istio service mesh, providing advanced traffic management capabilities.
• Contour — an Envoy-based controller focused on performance and security.

The choice depends on the project requirements: functionality, performance, integration with other tools, and ease of configuration.
