What is Kubernetes Ingress?
A K8s resource that manages external HTTP/HTTPS access to services inside the cluster. Routes traffic by hostname or URL path to different backend services.
Kubernetes Ingress is a intermediate-level concept that sits in the Kubernetes & Containers area of system design. Engineers reach for it whenever they need to reason about real-world trade-offs in that space — not just for textbook correctness, but because real production systems at companies like Netflix, Amazon, and Google make these decisions every day.
If you want to go deeper than this definition — with diagrams, code, and a quiz to lock it in — work through the "Kubernetes Ingress" lesson linked below. It walks through the why, the mechanism, the trade-offs, and how the giants actually use it in production.

Kubernetes Service
A stable network endpoint that load-balances traffic across a set of pods. Pods come and go, but the Service's IP and DNS name stay constant.
Reverse Proxy
A server that sits in front of your backend servers and forwards client requests to them. Handles SSL termination, caching, and load balancing.
Layer 7 Load Balancing
Load balancing at the application layer (HTTP) that can route based on URL paths, headers, cookies, or request content. More flexible but more CPU-intensive.
