Answer
Ingress controllers route HTTP/HTTPS traffic to services using host and path rules.
Quick Answer
An Ingress Controller (like nginx or Traefik) handles external HTTP/HTTPS traffic and routes it to internal Services based on host name and URL path rules. Instead of one LoadBalancer per Service (expensive), one Ingress Controller handles all external traffic routing. It also handles TLS termination, redirects, and path rewrites.
