Which architectural approaches are most effective for building scalable SaaS platforms? Our app started as a simple monolith too, and once we hit a few thousand active users, the cracks became obvious.

It wasn’t an overnight fix, but once the core pieces were independent, scaling actually became predictable instead of chaotic.
