    AWS SAA-C03 · Question 60 · Domain 4.3: Database Cost Optimization

    A startup is launching a new mobile app backed by Amazon DynamoDB. The marketing team expects the app to go viral, but they have no idea how much database traffic to expect. They want to ensure the database does not throttle requests, but they also want to avoid paying for unused capacity. Which DynamoDB capacity mode should they choose?

    Answer options:

    A.

    Provisioned capacity mode with Auto Scaling

    B.

    On-Demand capacity mode

    C.

    Provisioned capacity mode with a high initial capacity

    D.

    DynamoDB Standard-IA table class

    How to approach this question

    Match 'unpredictable traffic', 'no throttling', and 'pay per request' with DynamoDB On-Demand.

    Full Answer

    B.On-Demand capacity mode✓ Correct
    On-Demand capacity mode
    Amazon DynamoDB on-demand is a flexible billing option capable of serving thousands of requests per second without capacity planning. DynamoDB on-demand offers pay-per-request pricing for read and write requests so that you pay only for what you use. It is ideal for unpredictable workloads.

    Common mistakes

    Choosing Provisioned with Auto Scaling. Auto scaling is great for gradual changes, but On-Demand is better for unknown, sudden viral spikes.
