Cloud-Native vs Portable Infrastructure#

Every infrastructure decision sits on a spectrum between portability and fidelity. On one end, you have generic Kubernetes running on minikube or kind – it works everywhere, costs nothing, and captures the behavior of the Kubernetes API itself. On the other end, you have cloud-native managed services – EKS with IRSA and ALB Ingress Controller, GKE with Workload Identity and Cloud Load Balancing, AKS with Azure AD Pod Identity and Azure Load Balancer. These capture the behavior of the actual platform your workloads will run on.
