How do I keep cloud costs low?
- Start managed and serverless — pay for actual use; free tiers cover many small apps
- Right-size servers and databases; turn off unused resources
- Cache and use a CDN to reduce compute and bandwidth
- Set budgets and alerts in AWS/Azure/Google Cloud and spend limits on APIs
- Commit for discounts (reserved instances / savings plans) once usage is steady
- Review monthly — costs creep quietly
Why: most cloud waste is idle or oversized resources.
