Amazon Aurora Serverless v2 now supports up to 256 ACUs

Amazon Aurora Serverless v2 now supports database capacity of up to 256 Aurora Capacity Units (ACUs). 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 higher maximum capacity, customers can now use Aurora Serverless for even more demanding workloads. Instead of scaling up to 128 ACUs (256 GiB), the database can now scale up to 256 ACUs (512 GiB). You can get started with higher capacity with a new cluster or your existing cluster with just a few clicks in the AWS Management console. For a new cluster, select the desired capacity for the maximum capacity setting. For existing clusters, select modify and update the maximum capacity setting. For existing incompatible instances that don’t allow capacity higher than 128 ACUs, add a new reader with the higher capacity to the existing cluster and failover to it. 256 ACUs is supported for Aurora PostgreSQL 13.13+, 14.10+, 15.5+, 16.1+, and Aurora MySQL 3.06+.

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.
