The point about workload contention hitting right during launch day is painfully accurate. Running heavy analytics queries or background jobs on the same cluster serving live user logins is a silent killer. Even within a monolith, introducing basic connection pool discipline, read replicas, and a caching layer before your first traffic spike is the difference between surviving a launch and taking down your entire app.

Good call — that's exactly right, and worth calling out. I didn't want people to read "split by domain" and think none of this helps until they do a full rearchitecture. Pooling, a read replica, and caching are honestly the easiest wins precisely because they bolt onto a monolith with zero architecture changes — a couple days of work that can save you on launch day, way before you're ready for the bigger split.
