Replication Controller vs ReplicaSet vs Deployment

In this video, we deep dive into the fundamental Kubernetes controllers — ReplicationController, ReplicaSet, and Deployment — and understand how they work, why they exist, and when to use them in real-world Kubernetes workloads.

👉 You’ll learn:
✔ What a ReplicationController is and how it ensures pods are always running.
✔ How ReplicaSet improves on ReplicationController with better label selector support.
✔ Why Deployment is the recommended way to manage ReplicaSets with features like rollouts, rollbacks, and updates.
✔ Key differences and real examples of how these resources behave in a Kubernetes cluster.

🎓 Whether you’re a beginner preparing for the CKA/CKAD exam, a DevOps engineer mastering Kubernetes controllers, or just learning about application scaling and reliability in K8s — this video breaks it all down in a simple, practical way.
