and similar
+operational principles apply.
+

+will briefly introduce you to the main components that make up a Flink Cluster.

+## Anatomy of this Playground
+
+This playground consists of a long living
+[Flink Session Cluster]({{ site.baseurl
}}/concepts/glossary.html#flink-session-cluster) and a Kafka
+Cluster.
+
+A Flink Cluster always consists of a
+[Flink Master]({{ site.baseurl }}/concepts/glossary.html#flink-master) and one
or more
+[Flink TaskManagers]({{ site.baseurl
}}/concepts/glossary.html#flink-taskmanager). The Flink Master
+is responsible to handle Job submissions, the supervision of Jobs as well as
resource
