Day 52: Kubernetes Gateway API Deep Dive | Part 1 | GatewayClass, Gateway & Routes | CKA Course 2025 👉 GitHub Repository: https://github.com/CloudWithVarJosh/C... 👉 CKA 2025 Playlist:    • CKA Certification Course 2025   👉 Kubernetes Projects:    • DevOps Projects   📚 Welcome to Day 52! In this session, we begin our deep dive into the Kubernetes Gateway API, the modern successor to Ingress, designed to overcome its limitations and offer a more powerful, extensible, and role-oriented networking model. You’ll learn the fundamentals of Gateway API and how its key building blocks — GatewayClass, Gateway, and Routes (HTTP, TCP, UDP, gRPC) — work together to provide a flexible way to expose and manage traffic into your Kubernetes clusters. 🛠 What You’ll Learn: ✅ Why Ingress falls short in real-world scenarios ✅ Core concepts of Gateway API and its advantages ✅ Gateway API kinds: GatewayClass, Gateway & Routes ✅ How controllers and data planes differ in cloud-managed vs on-prem/self-managed clusters ✅ Step-by-step flow of how Gateway and HTTPRoute interact with the controller and data plane ✅ A clear mental model to distinguish the control plane (controller) from the data plane (proxies or cloud load balancers) 💡 By the end of this lecture: You’ll clearly understand how Gateway API organizes traffic management in Kubernetes, how it differs between cloud and on-prem setups, and how it sets the foundation for modern L4/L7 routing. 🔗 Stay Connected: 👉 LinkedIn:   / varun-joshi-2b516752   👉 GitHub: https://github.com/CloudWithVarJosh 💬 Got questions?
