Most containerized workloads run more efficiently on proprietary cloud container services. Kubernetes is justified only when you need cross-environment portability or deep extensibility.
Why idempotent or fully reproducible Dockerfiles are frequently promoted but often misplaced objectives compared to immutable artifacts and regular CI rebuilds.
