Pick Docker if…

  • You want consistent environments across dev, staging, and production
  • You're deploying to Kubernetes or any container platform

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)
