Red Hat OpenShift offers horizontal pod autoscaling (HPA) primarily for CPUs, but it can also perform memory-based HPA, which is useful for applications that are more memory-intensive than CPU-intensive. In this article, I demonstrate how to use OpenShift’s memory-based horizontal pod autoscaling feature (tech preview) to autoscale your pods if the demands on memory increase. The test performed in this article might not necessarily reflect a real application. The tests only aim to demonstrate memory-based HPA in the simplest way possible.
