Architecture

In order to manage, monitor, and optimize the modern data applications running on your EMR cluster, Unravel Server needs data corresponding to the EMR cluster as well as about the modern data apps running on the cluster. This information includes metrics, configuration information, and logs. Some of this data is pushed to Unravel, and some is pulled by the daemons in Unravel Server. In order for this to work, you must allow both inbound and outbound traffic between Unravel Server (on the EC2 instance) and the EMR cluster. For details, see Planning guidance.

Backing up Unravel amounts to RDS backup (if that is the chosen database) and backing up the state of the Unravel Server. For more information, see Operational guidance.
