Kubernetes is an open-source platform that automates deploying, scaling, and managing containerized applications. It provides primitives for service discovery, load balancing, storage orchestration, automated rollouts/rollbacks, and self-healing.

Core Kubernetes concepts:

• Pods, Deployments, and ReplicaSets: Units of scheduling and workload lifecycle management.
• Services and Ingress: Networking primitives for internal and external access.
• ConfigMaps and Secrets: Configuration and sensitive data management.
• Operators and CRDs: Extending Kubernetes with domain-specific controllers and APIs.

Kubernetes standardizes app operations across environments—from laptops to cloud and edge so teams can focus on features not infrastructure. It enables declarative management, automated scaling, and improved resource utilization while fostering a broad ecosystem.

Key advantages of Kubernetes:

• Portable and declarative application deployment across clouds and on-premises.
• Automated scaling, rolling updates, and self-healing for resilient services.
• Ecosystem of tools for CI/CD, observability, and service meshes.
• Improved resource efficiency via bin-packing and scheduling policies.
