What is Kubernetes and why is it important in modern application deployment?

Kubernetes is an open-source container orchestration platform that automates deployment, scaling, and management of containerized applications.\n\nWhy it's important:\n• Automates container lifecycle management\n• Provides service discovery and load balancing\n• Enables horizontal scaling and self-healing\n• Offers declarative configuration management\n• Supports multi-cloud and hybrid deployments\n\nExample: Instead of manually managing containers across servers, Kubernetes automatically schedules pods, restarts failed containers, and scales applications based on demand.\n\nBest Practices:\n• Use namespaces for resource isolation\n• Implement resource limits and requests\n• Follow the principle of least privilege\n• Use health checks for reliability
