That looks great. Thanks @amaltaro
Just an idea here - While looking at this new picture I quite liked how you separated the MongoDB as a CMSWEB managed DB and this drove me to the idea, could we also split the central CMSWEB hosted Services in the middle of the diagram in two pieces - one which are just the services as a set of K8 deployed services and the other the CMSWeb managed CouchDB ....?

I would prefer to keep the "popular" names for WM services. But I agree that separating CouchDB in its own box would make it more readable. I won't have time to update it today, as I need this diagram for tomorrow. But will keep it in mind whenever we update it again. Thanks for the suggestion.
