How Host Groups Compare to Proxy Touchpoints

Host groups and proxy touchpoints are alike in the following ways:

Both run on agents.
Both access remote hosts through SSH.
Both support the same CA Process Automation operators that can be executed on remote hosts through SSH.
The configured categories for the required operators must be running on the agent host on which the proxy touchpoint or host group is configured.

Host groups differ from proxy touchpoints in the following ways:

The relationship between a host group and potential target hosts is one to many, whereas the relationship between a proxy touchpoint and the target host is one to one.
Content designers can target multiple hosts with associated proxy touchpoints by specifying a touchpoint group. Content designers cannot target multiple hosts that have only a host group reference.
Content designers specify a remote host as a target by its touchpoint name when the remote host has an associated proxy touchpoint. Content designers specify a remote host as a target by its IP address or FQDN when the remote host has a host group reference.
