How to use workload partitioning with Red Hat OpenShift Container Platform

Workload Partitioning is a powerful feature in Red Hat® OpenShift® Container Platform designed to provide CPU core isolation between critical OpenShift system components and user-deployed workloads. This isolation is particularly beneficial in resource-constrained environments such as single node OpenShift (SNO) or 3-node compact clusters, where system services and user applications run on the same hosts and compete for CPU resources.

By dedicating specific CPU cores to the system and others to workloads, you can achieve more predictable performance and prevent user applications from impacting the stability and responsiveness of the cluster's control plane.

This learning path will show how to configure and verify workload partitioning. We will deploy sample pods and a virtual machine to observe how the CPU isolation is enforced.

Note: This is an example walkthrough of the feature. Please refer to the Red Hat OpenShift Container Platform documentation for more information.
