 ## CFEngine policy servers and hosts
 
 There are basically two categories of machines in a CFEngine environment: policy servers and their client hosts. Policy servers are responsible for making policy files available to each of the client hosts that have registered with it (a.k.a. bootstrapped), including itself. Hosts on the other hand are responsible for ensuring they continuously pull in the latest policy files, or changes to them, from the policy server. They are additionally responsible for ensuring they remain fully compliant with the instructions contained within the policy files, at all times.
 
 The role of a particular machine where CFEngine is deployed determines which of the components will be installed and running at any given moment.
