Can Kubernetes Save Infra Cost?

Kubernetes is based on container technology. Containers by definition are created to save infra cost. All we need is to install a container engine like docker, using which we can create containers. Kubernetes, being a popular container orchestration engine, offers auto-scaling of pods. Cluster and Pods can be auto-scaled as and when required, without us having the need to provision the infrastructure well in advance like on-prem.
