You're presumably thinking about connection pools etc. for relational DBs. They are a pain, for sure. But the end is nigh for these things, Everything is (or will become, if not already) an API call. It's a simple HTTPS request, that's signed for authentication (and to prevent tampering), that delivers the SQL request (or whatever). No complex connection setup, no persistent connection pooling, no fighting for shared resources. The auth and request are combined in the same, single, lighter-weight HTTPS request.
