Overview

Services provide stable networking for Pods, while Ingress manages external HTTP/HTTPS access. Together they enable service discovery and load balancing.

<aside> ℹ️ Why It Matters: Understanding Services & Ingress is essential for building robust, scalable, and secure modern applications.

Key Concepts

• [x] ClusterIP - Internal cluster access
• [x] NodePort - External port mapping
• [x] LoadBalancer - Cloud load balancer
• [x] Service Discovery - DNS resolution
• [x] Ingress Controllers - Nginx, Traefik
• [x] Path-Based Routing - URL routing
• [x] TLS Termination - HTTPS support
• [x] Session Affinity - Sticky sessions

Common Use Cases

<aside> 💡 Where to Apply Services & Ingress
