## Hidden costs and limits

- Storage costs grow linearly with metric cardinality and retention period
- No built-in long-term storage -- need Thanos, Cortex, or managed solution
- No native high availability -- requires manual federation or Thanos
- Amazon Managed Prometheus: $0.03 per 10M metric samples ingested, $0.003 per 10M samples queried
- Engineering time to manage and tune TSDB, alerting rules, and scrape configs
