## Container Runtime vs Cluster Orchestrator
Docker and Kubernetes are not competing technologies — they are complementary layers of modern cloud-native infrastructure.
### Docker (Containerization)
Docker isolates applications and their dependencies into lightweight, standalone container images. It manages container lifecycles on a single host.
### Kubernetes (Orchestration)
Kubernetes (K8s) automates the deployment, autoscaling, healing, service discovery, load balancing, and rolling updates of containerized applications across a cluster of server nodes.
| Capability | Docker (Single Host / Compose) | Kubernetes (Cluster Orchestration) |
| :--- | :--- | :--- |
| **Scope** | Single server / instance | Multi-node server clusters |
| **Auto-healing** | Basic container restart | Pod rescheduling across healthy nodes |
| **Autoscaling** | Manual scaling | Horizontal Pod Autoscaler (HPA) |
| **Load Balancing** | Basic host mapping | Ingress Controller, Service IP balancing |
