Hi, We want to run a Proof-of-Concept of Datahhub on our AWS infrastructure. Our support engineers are using AWS CDK to manage our infrastructure, so I'm trying to figure out what I need to tell them to get a proper environment up and running... One thing I was wondering about: in the Deploying to AWS section in the documentation there is this part about exposing the datahub-frontend via a load balancer. Shouldn't the datahub-mce-consumer be exposed as well? As to receive messages from the ingestion framework?

The MCE consumes a Kafka topic.

Correct^

You may want to expose datahub-gms if you want to ingest through the rest end point. But as mentioned above, you should send events to the MetadataCangeEvent_v4 topic to ingest through kafka.

check.
