Resource limit

As explained in Google Anthos in Action

A Kubernetes resource quota is a namespace-scoped control that limits the aggregate resource consumption of objects in a namespace.

A Kubernetes resource quota limits the aggregate resource consumption of objects within a namespace. It provides a namespace-scoped boundary for managing shared cluster capacity and supports safer multitenancy. section 3.2.6

Namespaces form logical partitions of a cluster. Resource quotas operate within those partitions alongside RBAC, network policies, and namespace security resources, allowing tenant environments to be separated logically while sharing physical infrastructure. section 3.2.6

Use resource limits as one part of namespace-level cluster governance:

  • Apply quotas at the namespace boundary rather than treating them as cluster-wide controls. section 3.2.6
  • Combine quotas with RBAC, network policies, and namespace security resources when designing a safer multitenant cluster. section 3.2.6
  • Distinguish Kubernetes resource quotas from Istio policy features such as rate limits and quotas, which govern service-mesh behavior. section 3.2.6 section 4.3

How Google Anthos in Action covers it

How deep it goes
Defines namespace scope and connects quotas to cluster governance, but does not provide quota fields, commands, or configuration steps.
What it assumes
Teaches namespaces as logical cluster partitions before relating them to resource quotas and other namespace-level controls.
What you can do after
Evaluate namespace-level resource limits as one component of a multitenant Kubernetes governance design.
How it connects
Connects resource quotas with namespaces, multitenancy, RBAC, network policies, namespace security, and Istio policy controls.
