<!-- overview -->
By default, containers run with unbounded [compute resources](/docs/user-guide/compute-resources) on a Kubernetes cluster.
With resource quotas, cluster administrators can restrict resource consumption and creation on a {{< glossary_tooltip text="namespace" term_id="namespace" >}} basis.
Within a namespace, a Pod or Container can consume as much CPU and memory as defined by the namespace's resource quota. There is a concern that one Pod or Container could monopolize all available resources. A LimitRange is a policy to constrain resource allocations (to Pods or Containers) in a namespace.

<!-- overview -->
When several users or teams share a cluster with a fixed number of nodes,
there is a concern that one team could use more than its fair share of resources.
Resource quotas are a tool for administrators to address this concern.
