+===== Orchestration =====
+Details are here: https://kjhenner.gitbooks.io/puppet-quest-guide/content/quests/application_orchestrator.html
+Orchestration allows to install dependent applications in the right order.
+It works as following:
+  - setup the node to know the orchestrator
+  - create an Application, which may combine multiple nodes to a single semantical unit (MySQL Server, Apache with PHP application )
+    - setup orchestrator user with the rights
+    - setup an **artificial, public resource** to share the data between nodes (**in ruby**)
+    - define, which node **produces** data to fill artificial, public resource. Which node consumes data from artificial, public resource.
+    - declare the resource
+    - in site.pp declare - which part of the application will be installed on which node.
