+  applications deployed on the runtime or system components of Cloud Foundry
+  itself. It also extends to the runtime logs and metrics, e.g. Gorouter access

+
+CloudFoundry organizes application deployments (apps) by spaces contained in
+organizations (orgs). Names are unique only in their respective enclosing
+entity. Ids are unique in the entire CloudFoundry installation. Different
+instances of the same application are separated by an integer index. Apps can
+consist of a main job and multiple tasks and side-cars, which can be
+distinguished by different process attributes.
+
+CloudFoundry can also emit signals from system components. They use a different
+approach as applications, since they are not organized into orgs and spaces.
+They align with the Bosh deployment tool of CloudFoundry.
