📚 Welcome to Day 25! 🚀
Understanding Kubernetes architecture is crucial for mastering how the system operates and extends functionality. Today, we’ll dive deep into Kubernetes Core and Extended Architecture, exploring the essential components and how Kubernetes enables flexibility through plugins, add-ons, and third-party extensions.

📝 What We’ll Cover:
✅ What is Kubernetes Core? – Understanding the foundation of Kubernetes.
✅ Control Plane Components – API Server, Controller Manager, Scheduler, etc.
✅ Node Components – Kubelet, Kube Proxy, and Container Runtime.
✅ Kubernetes Extensions: Beyond the Core – Extending Kubernetes functionalities.
✅ Types of Extensions:
🔹 Plugins – How Kubernetes integrates with external systems.
🔹 Add-Ons – Enhancing cluster capabilities.
🔹 Third-Party Extensions – Customizing Kubernetes for enterprise needs.
✅ Kubernetes Interfaces – CRI, CNI, and CSI.
✅ Why Kubernetes Uses a Plugin-Based Architecture?

💡 By the end of this lecture:
You’ll have a solid understanding of Kubernetes core architecture and its extensibility model, helping you optimize cluster functionality and ace your CKA exam!
