Salt SSH is an agentless option provided by SaltStack that allows users to run Salt commands without having to install a minion on the remote device or node.
The main requirements to use Salt SSH is that the remote system has SSH and Python enabled.
Salt SSH connects to the remote system and installs a lightweight version of SaltStack in a temporary directory, and can optionally delete this temporary director once the operations have completed.
Salt SSH is considerably slower than the 0MQ distributed messaging library, but it is considered faster than logging into the system and executing commands.
