- Docs: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_MySQL.html
- Docs (llms.txt): https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/llms.txt
- Data model: Relational (community MySQL)
- Query language: MySQL SQL (identical to community)
- Compatibility: IS community MySQL (not "compatible" — it IS MySQL)
- Serverless: No (fixed instance types)
- Scale to zero: No
- VPC required: Yes
- Multi-region: Cross-region read replicas (async)
- Free Tier: new-account AWS Free Tier — $100 in credits at sign-up plus up to $100 more ($200 total), usable across eligible services including RDS/Aurora for up to 12 months
- Min cost: $0 (free tier) → ~$15/month after
- Time to first query: 10-15 min (VPC + instance + configuration)
- Key features: All MySQL features, reserved instances (up to 60% off), full portability, Multi-AZ deployments
- Limitations: No auto-scaling compute, manual instance sizing, no serverless option
- Best for: Cost-sensitive MySQL workloads, portability priority, teams wanting standard MySQL with no proprietary layer
- Not for: Variable traffic needing auto-scaling (Aurora MySQL is better), new apps without MySQL requirement
