 You can use machine management to flexibly work with underlying infrastructure like Amazon Web Services (AWS), Azure, Google Cloud Platform (GCP), OpenStack, Red Hat Virtualization (RHV), and vSphere to manage the {product-title} cluster.

 It is important to have a cluster that adapts to changing workloads.
 
 Machine management is implemented as a xref:../operators/understanding/crds/crd-extending-api-with-crds.adoc#crd-extending-api-with-crds[Custom Resource Definition](CRD).

 To xref:../machine_management/applying-autoscaling.adoc#applying-autoscaling[autoscale] your {product-title} cluster, you must first deploy a cluster autoscaler, and then deploy a machine autoscaler for each machine set.
 The cluster autoscaler increases and decreases the size of the cluster based on deployment needs.
