Aurora Serverless

On-demand autoscaling configuration of Amazon Aurora that adjusts database capacity in fine-grained increments.

Definition

Aurora Serverless v2 scales compute capacity measured in Aurora Capacity Units (ACUs) up and down in fine increments based on load, and can coexist with provisioned instances in a cluster. It can scale to zero ACUs with auto-pause, suiting variable, intermittent or unpredictable workloads.

Example

A development database scales down to zero when idle overnight and back up when engineers start work.

Exam tip

Choose Aurora Serverless when the database workload is unpredictable or intermittent.
