vSphere Management Assistant
The VMware vSphere Management Assistant (vMA) is a prepackaged Linux virtual machine in which administrators can deploy scripts and select third-party agents to manage ESX and ESXi systems. Software included in vMA includes vSphere CLI and an authentication component that supports non-interactive login. It also includes DCLI commands which allow you to manage services that are available via the vSphere REST API and are presented by the vSphere Automation SDK interfaces.
Note: vMA is deprecated and vMA 6.5 is the last release, please see the vMA Release Notes for further information and alternative functionality.
