In puppet, what is the stand-alone architecture?

Every node that is managed has the entire copy of the info of configuration of yours in a stand-alone architecture which can run a puppet. Every node compiles the catalogue of its own. The nodes that are managed run the application of Puppet Apply in the stand-alone architecture. The application of Puppet Apply is generally run as a task that is scheduled. It could also be run on demand for small tasks of configuration. The Puppet Apply application can be run on demand for configuring a server in the starting. For the compilation of a catalogue for nodes that are managed by Puppet Apply, it requires access into some of the configuration data's sources.
