Pick Kubernetes if…
- You're running many services that need automated scaling
- You need self-healing, rolling deployments, and zero-downtime updates
- Your cloud provider offers managed K8s (GKE, EKS, AKS)
Pick Docker if…
- You want consistent environments across dev, staging, and production
- You're deploying to Kubernetes or any container platform
- You need to isolate services in a microservices architecture
