PowerShell Core introduces the concept of remoting over SSH. This provides a useful alternative to remoting over HTTPS, which avoids the burden of managing certificates: https://github.com/PowerShell/PowerShell/blob/866b558771a20cca3daa47f300e830b31a24ee95/docs/new-features/remoting-over-ssh/README.md.
The SSH transport for remoting cannot be used from Windows PowerShell, only PowerShell Core.
