Love this. Most MVPs die of no users, not lack of Kubernetes. As a rule, small teams should ship on a single box, keep logs, backups, and alerts, and move. Big-cloud Rube Goldberg diagrams don’t replace product-market fit. Java with Quarkus or a tiny Go service + a Postgres on a VPS gets you to feedback in a day; swap in AWS later when you actually feel the pain. Use AI for scaffolding, not ceremony; measure by shipped features, not diagrams. Build the UI as web components so migrations are painless. Ship early, learn fast, and keep the architecture boring until reality demands otherwise.
