Premature optimization can lead to overengineering and spending unnecessary time on tech solutions that are not currently needed.
At early stages (1–100 users), focus on a simple app structure, basic database like Postgres or SQLite, easy deployment methods, error tracking, and feedback collection.
Scaling should be a reaction to real usage, not just a prediction based on hopeful scenarios.
Start with a simple stack that is easy to manage and can handle considerable load before needing complex infrastructure.
Know when it's necessary to scale: database CPU usage high under normal load, timeouts during usage spikes, frequent support tickets about slowness, or constraints hindering feature updates.
Simplify deployment with monolithic architectures, such as Node.js + Postgres or Rails/Laravel + SQLite/MySQL.
Focus on building for a smaller user base that values your product; earn scaling challenges as your user base grows.
Keep the approach simple and momentum-driven; Kubernetes or complex setups can wait until needed for significant scalability.
Prioritize user feedback, rapid iteration, and product improvements over overly complicating the infrastructure setup in the early stages of product development.
