+
+<!-- overview -->
+
+In order to support latency-critical and high-throughput workloads, Kubernetes offers a suite of Resource Managers. The managers aim to co-ordinate and optimise node's resources alignment for pods configured with a specific requirement for CPUs, devices, and memory (hugepages) resources. 
+
+<!-- body -->
+
+The main manager, the Topology Manager, is a Kubelet component that co-ordinates the overall resource management process through its [policy](/docs/tasks/administer-cluster/topology-manager/).
+
+The configuration of individual managers is elaborated in dedicated documents:
+
+- [CPU Manager Policies](/docs/tasks/administer-cluster/cpu-management-policies/)
+- [Device Manager](/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/#device-plugin-integration-with-the-topology-manager)
+- [Memory Manger Policies](/docs/tasks/administer-cluster/memory-manager/)
