Amazon Aurora Serverless v2 supports scaling to zero capacity

Amazon Aurora Serverless v2 now supports scaling to 0 Aurora Capacity Units (ACUs). This launch enables the database to automatically pause after a period of inactivity based on database connections. When the first connection is requested, the database will automatically resume and scale to meet the application demand. Aurora Serverless v2 measures capacity in ACUs where each ACU is a combination of approximately 2 gibibytes (GiB) of memory, corresponding CPU, and networking. You specify the capacity range and the database scales within this range to support your application’s needs.

With 0 ACUs, customers can now save cost during periods of database inactivity. Instead of scaling down to 0.5 ACUs, the database can now scale down to 0 ACUs. You can get started with this feature with a new cluster or your existing cluster with just a few clicks in the AWS Management console. For a new cluster, set 0 ACUs for the minimum capacity setting. For existing clusters, update to supported versions and then modify the minimum capacity setting to 0 ACUs. 0 ACUs is supported for Aurora PostgreSQL 13.15+, 14.12+, 15.7+, and 16.3+, and Aurora MySQL 3.08+.

Aurora Serverless is an on-demand, automatic scaling configuration for Amazon Aurora. It adjusts capacity in fine-grained increments to provide just the right amount of database resources for an application’s needs.
