An abstraction used by Kubernetes to support isolation of groups of resources within a single {{< glossary_tooltip text="cluster" term_id="cluster" >}}.

Namespaces are used to organize objects in a cluster and provide a way to divide cluster resources. Names of resources need to be unique within a namespace, but not across namespaces. Namespace-based scoping is applicable only for namespaced objects (e.g. Deployments, Services, etc) and not for cluster-wide objects (e.g. StorageClass, Nodes, PersistentVolumes, etc).
