Nutanix Acropolis Operating System (Nutanix AOS) is an operating system for the Nutanix hyper-converged infrastructure platform. AOS comes with a built-in hypervisor called Acropolis Hypervisor, or AHV. By using Rancher with Nutanix AOS (AHV), you can bring cloud operations on-premises.

Rancher can provision nodes in AOS (AHV) and install Kubernetes on them. When creating a Kubernetes cluster in AOS, Rancher first provisions the specified number of virtual machines by communicating with the Prism Central API. Then it installs Kubernetes on top of the VMs.

A Nutanix cluster may consist of multiple groups of VMs with distinct properties, such as the amount of memory or the number of vCPUs. This grouping allows for fine-grained control over the sizing of nodes for each Kubernetes role.
