## What the models said for it

- "Supported Engines: Most comprehensive—supports 6 engines ... Choose AWS RDS/Aurora if you need broad engine support and cloud-native performance" (MiniMax M2.5, Managed databases)
- "For Most Users: Start with AWS RDS (broadest engines, mature) or Google Cloud SQL (price/performance edge)—but POC costs first." (Grok 4.1 Fast, Managed databases)
- "The Corporate Standard: AWS RDS / Amazon Aurora ... Amazon Aurora (preferred over standard RDS for higher performance and scalability)" (Qwen 3.7 Flash, Managed databases)
- "the most common winning choice for mid-market B2B is managed PostgreSQL — either AWS Aurora PostgreSQL or AWS RDS PostgreSQL" (DeepSeek V4 Flash, Managed databases)

## And against it

- "Amazon has significantly less detailed documentation for AWS RDS limitations compared to Azure SQL.  AWS RDS SQL Server lacks the native backup solution for restoring a database to point in time" (Claude Haiku 4.5, Managed databases)
- "Amazon RDS: Be cautious if you need *extreme write throughput*, *near-infinite horizontal scaling*, *full engine control*, or *global write distribution*" (Perplexity Sonar, Managed databases)
- "it may not be suitable for applications that require custom kernel parameters, filesystem-level tuning, or unsupported database extensions" (Llama 4 Maverick, Managed databases)
- "Avoid (or use with caution): Amazon RDS if you require root access to the OS for kernel tuning or custom extensions." (GLM 4.7 FlashX, Managed databases)
