Enterprise tooling probably needs to make event sourcing out of the box easy to do, with metrics being either a real time stream they can tap into, or an ETL process fed by that stream.

Having a decent integration layer is important: I'm about to spend my Christmas "enjoying" Apache Camel installs to get up to speed there, and it's probably wise to move all auth out to something like Keycloak so that it's just "done" and federation back to AD is config, not code.

As to getting data synching between environments, well... that gets fun all by itself...
