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).
