I'm not into containers (in much the same way the article embraces 'herds not pets' we serverless folks embrace 'cockroaches not herds') but you can connect to DBs from a lambda in <20 ms.
The DB itself is typically provided by the cloud provider and is usually a traditional cluster setup. Is it stateful? Yes, but you could throw it into a river, not know anything about how it was configured, connect another box to the cluster and get the capacity back. Exactly like whatever was running the lambda.
