When should I scale my database?

Plan to scale when you reach 70-80% capacity. For critical apps, start migration at 50%. Factor in growth rate - if doubling monthly, scale proactively.

What are typical database costs?

Cloud databases: $50-200/month for small apps, $500-2000/month for medium traffic. Self-hosted can be cheaper but requires DevOps. Consider read replicas for scaling reads cheaply.

How do I reduce database storage costs?

Archive old data to cold storage, compress large text fields, use efficient data types, implement data retention policies, and consider time-series databases for metrics data.
