Amazon Aurora Serverless Enhancements

Amazon Aurora serverless now scales in even larger steps, adding up to 16 ACUs to its current capacity within a second and continuing to scale up to 256 ACUs as your workload grows. This enhancement is enabled by default on all Aurora serverless clusters running on platform version 3 or 4, with no configuration changes required. Existing clusters on platform versions 1 and 2 can upgrade directly to the latest platform version 4 to benefit from these improvements.

What to do

  • Verify your cluster's platform version in the AWS Management Console under the instance configuration section, or via the RDS API's ServerlessV2PlatformVersion parameter.
  • Upgrade existing clusters on platform versions 1 and 2 to platform version 4 for the new scaling enhancements.
  • Create an Aurora serverless database in the AWS Management Console to start benefiting from the new scaling capabilities.
