    AWS SAA-C03 · Question 64 · Domain 4.3: Database Cost Optimization

    A company is migrating a legacy application to AWS. The application requires a relational database. The database will be heavily used during the day but completely idle at night. The company wants to minimize licensing and compute costs. Which solution is MOST cost-effective?

    Answer options:

    A.

    Amazon RDS for Oracle with a Reserved Instance

    B.

    Amazon EC2 with SQL Server installed

    C.

    Amazon Aurora Serverless

    D.

    Amazon DynamoDB

    How to approach this question

    Combine 'relational', 'idle at night', and 'minimize licensing'. Aurora Serverless fits perfectly.

    Full Answer

    C.Amazon Aurora Serverless✓ Correct
    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.

    Common mistakes

    Choosing DynamoDB, ignoring the 'relational' requirement.
