Can we run containers of same pod on different nodes?

Containers of the same Pod are always co-located and co-scheduled, and run in a shared context on the same node. In case of a Node failure, new identical Pods will be deployed on other available Nodes. The Pod is the atomic deployment unit on the Kubernetes platform.

Does Google use Kubernetes internally?
