Customers that use CDP Operational Database Experience (or the "Operational Database with SQL" template in DataHub) need to deploy their applications on an edge node that has connectivity with the database. Edge nodes are pre-configured to work with Cloudera's FreeIPA based DNS solution and within the Kerberos domain of the SDX.
Creating an edge node is now as simple as selecting the "COD Edge Node" template in Data Hub and is available for both AWS & Microsoft Azure.
