They are most often defined types (for reusability), but can also consist of classes or even native resources, such as files, in very simple cases. Application components are created by the export, consume, or require metaparameters that are used in an application declaration.

The manifest for example::app2 would still be located at manifests/example/app2.pp. Application components can explicitly list the values they export and consume in their individual manifests by placing an additional statement at the bottom of the manifests:

class example::app2 (
# $db_host is provided by the consume of the Database
  $db_host,
) {
# Any resources, defined types or class calls in a regular manifest would be placed here.
}
