Explain the difference between Pods, Deployments, and Services in Kubernetes.

These are fundamental Kubernetes objects that serve different purposes in application management.\n\nPod: Smallest deployable unit containing one or more containers\n• Shares network and storage\n• Ephemeral and replaceable\n• Usually managed by higher-level controllers\n\nDeployment: Manages replica sets and pod lifecycle\n• Ensures desired number of pod replicas\n• Handles rolling updates and rollbacks\n• Provides declarative updates\n\nService: Provides stable network endpoint for pods\n• Load balances traffic across pod replicas\n• Offers service discovery\n• Maintains consistent IP and DNS name\n\nExample: A web application deployment creates multiple pod replicas, while a service exposes them through a single endpoint.\n\nBest Practices:\n• Never create pods directly in production\n• Use services for internal communication\n• Implement proper labeling strategies
