# Container Orchestration Fundamentals

- **Need for Orchestration:**
    
    
    - Scaling applications.
    - Self-healing of workloads.
    - Load balancing.
    - Resource optimization.
- **Kubernetes as an Orchestration Tool:**
    
    
    - Managing containerized workloads.
    - Scheduling containers on nodes.
    - Ensuring desired state (via Deployments, ReplicaSets).
- **Core Orchestration Features in Kubernetes:**
    
    
    - Automatic scaling (Horizontal Pod Autoscaler).
    - Rolling updates and rollbacks.
    - Service discovery and networking.
    - Persistent storage management.
- **Workload Orchestration Concepts:**
    
    
    - Pods as the smallest deployable unit.
    - Running multiple containers in a Pod (e.g., sidecar pattern).
