Aurora Serverless automatically starts, scales, and shuts down database capacity based on demand. You get Aurora’s performance without provisioning or managing instances — ideal for variable or intermittent workloads.

When to choose it

The tell is a relational workload with unpredictable or infrequent traffic — a dev/test database, a new app with unknown load, or spiky usage — where paying for an always-on instance would waste money. Steady heavy load still favors provisioned Aurora.

Test yourself

Practice question

A new application has unpredictable, intermittent database traffic and the team doesn’t want to pay for a database running 24/7. Which option?

  1. Provisioned Aurora with a large instance
  2. Aurora Serverless
  3. A fixed RDS Single-AZ instance
  4. DynamoDB provisioned capacity
👉 Click to reveal the answer & explanation

Correct answer: B. Aurora Serverless scales capacity up and down (even to zero) with demand, so you pay for what you use — ideal for intermittent, unpredictable load. Provisioned options (A, C) pay for always-on capacity; DynamoDB (D) is NoSQL, not a relational fit here.
