Hi Dominik,
Your observation is right, running the JobManager and TaskManager on the
same node is no problem. If that machine fails, both services will be
affected, but as long as you have infrastructure in place (YARN for
example) to start them somewhere else, nothing bad will happen.

Hi,
It is generally recommended for streaming engines, also including Flink to run
a separate master node - in the case of Flink, the JobManager.
However, why should one in Flink run the JobManager on a separate node?
Performance wise, the JobManager isn’t intense unlike of course TaskManager
