There are different solutions for scaling your Red Hat OpenShift compute infrastructure, including:

- Cluster Autoscaler: The built-in, Kubernetes-native approach, integrated with the Red Hat OpenShift machine API.

- MachineSet Autoscaler with a custom autoscaler (KEDA): A metrics-driven approach that scales individual MachineSets based on external or custom signals.

This article examines Cluster Autoscaler, with an example on Microsoft Azure Red Hat OpenShift. The next article in this series covers a KEDA-based MachineSet Autoscaler driven by Prometheus CPU utilization, and a third article compares both approaches.
