Look for 'relational database', 'idle at night', and 'minimize costs'.
Full Answer
C.Amazon Aurora Serverless✓ Correct
Amazon Aurora Serverless
Amazon Aurora Serverless is an on-demand, auto-scaling configuration for Amazon Aurora. It automatically starts up, shuts down, and scales capacity up or down based on your application's needs. It is perfect for infrequent, intermittent, or unpredictable workloads.
Common mistakes
Choosing RDS and writing custom scripts to stop/start it, which violates the 'without manual intervention' (or custom scripting overhead) principle when a native solution exists.
