+The JobManager coordinates every Flink deployment. It is responsible for both *scheduling* and *resource management*.
 
 By default, there is a single JobManager instance per Flink cluster. This creates a *single point of failure* (SPOF): if the JobManager crashes, no new programs can be submitted and running programs fail.
