Run the Playbook

Many enterprise applications require multiple virtual machines, web frontends, app layers, and databases. With Ansible and Nutanix AHV, you can define entire application stacks in YAML and deploy them with a single command. This playbook demonstrates how to deploy and configure multiple VMs in a repeatable fashion.
