build what works. optimize later

A single executable on a modest cloud instance can often handle the entire user load of a well-funded startup through its first five to ten years of growth. The bottleneck is almost always the database, not the application architecture.

Nothing worse than premature optimization. I think anyways.

IMO this architecture took off because “monoliths” became too “hard” to upgrade.
