Cloud Management Platform (CMP) runs a remote script either over SSH or WinRM, which works on any platform, or through a platform-specific mechanism, which is available on a few. Some operating systems and platforms require setup first; see [OS-specific requirements](/docs/cmp/use/orchestration/remote-scripts/os-specific-requirements/).

## SSH and WinRM

The generic method works on a server of any resource technology. What it needs is a network route from the CMP appliance to the server and credentials that CMP can authenticate with. The platform the server runs on does not matter.

- **\*nix servers.** CMP copies the script to the server with `scp` and runs it over `ssh`.
- **Windows servers.** CMP uses native WinRM.

See [Authentication requirements](/docs/cmp/use/orchestration/remote-scripts/authentication-requirements/) for the credentials involved, and [OS-specific requirements](/docs/cmp/use/orchestration/remote-scripts/os-specific-requirements/) for what to enable on the target server.

## Platform-specific execution

These platforms can run a script through their own channel, so CMP does not need SSH or WinRM access to the server at all.

| Platform | Mechanism | Used by default |
| --- | --- | --- |
| VMware vCenter | VMware Tools | Yes |
| Amazon Web Services | See [AWS tech-specific script execution](/docs/cmp/use/orchestration/remote-scripts/aws/) | No, add the parameter |
| Azure | See [Azure tech-specific script execution](/docs/cmp/use/orchestration/remote-scripts/azure/) | No, add the parameter |
| Oracle Cloud Infrastructure | See [OCI tech-specific script execution](/docs/cmp/use/orchestration/remote-scripts/oci/) | No, add the parameter |

Turning platform-specific execution on or off is covered in [Configure remote script method](/docs/cmp/use/orchestration/remote-scripts/configure-method/).

## Platform notes

**Hyper-V.** CMP can read the IP address of a Hyper-V guest as long as Hyper-V knows it. That is reliable for Windows guests; Linux guests may need extra configuration, depending on the distribution, before Hyper-V reports an address. Without an address, CMP cannot open an SSH or WinRM session.
