DevOps Glossary

Kubernetes ResourceQuota is a Kubernetes API object that sets usage limits for a namespace, controlling how much CPU, memory, storage, and how many objects a team, application, or environment can consume. Platform and DevOps teams use it to keep one workload from exhausting shared cluster capacity, such as limiting a development namespace to 20 CPU cores, 40Gi of memory, 500Gi of persistent volume claims, and 50 services. A ResourceQuota can cap requested resources, hard limits, storage classes, pods, config maps, secrets, services, jobs, and other namespace-scoped objects. It does not reserve capacity by itself or control individual pod defaults, so teams often pair it with LimitRange, requests, and limits to make workload behavior predictable. ResourceQuota is most useful in multi-team clusters, CI environments, staging namespaces, and managed platforms where fair usage, cost control, and operational safety matter.
