C
Ansible works by connecting to your nodes and pushing out small programs, called ג€Ansible modulesג€ to them. These programs are written to be resource models of the desired state of the system. Ansible then executes these modules (over SSH by default), and removes them when finished.
Chef is a much older, mature solution to configure management. Unlike Ansible, it does require an installation of an agent on each server, named chef-client. Also, unlike Ansible, it has a Chef server that each client pulls configuration from.
