| Feature | Docker | Kubernetes |
|---|---|---|
| Purpose | Packages and runs individual containers | Orchestrates many containers across a cluster |
| Complexity | Simple to learn and use | Significant learning curve and operational overhead |
| Best fit for small apps | Sufficient on its own for simple deployments | Often overkill for small, single-service apps |
| Best fit for scaling complex systems | Limited orchestration capabilities alone | Built specifically for scaling and self-healing |
| Ecosystem and tooling | Strong, simple tooling | Vast ecosystem (Helm, Istio, operators) |
