Alfredo,

 From Freezer documentation: 
https://docs.openstack.org/freezer/latest/user/freezer-agent.html#freezer-scheduler

"The freezer-scheduler is one of the two freezer components which is run 
on the client nodes; the other one being the freezer-agent. It has a 
double role: it is used both to start the scheduler process, and as a 
cli-tool which allows the user to interact with the API."
