Large organizations centralize EKS access using IAM federation, RBAC, and short-lived credentials to enforce least privilege and audit compliance.
Single-node K3s is a pragmatic choice for homelabs and lightweight production workloads, offering Kubernetes compatibility without the overhead of multi-node clusters.
Use containerd directly with kaniko for building images and avoid DIND complexities.
Use Velero for cluster state, Kube-state-metrics for workloads, and Rook/Ceph for storage, but expect manual steps for dependencies and validation.
Internal Kubernetes storage for stateful services is viable for small-scale or isolated workloads but introduces complexity and risk at larger scales.
