Legacy Aurora Serverless v1 cluster settings (engine_mode = 'serverless' and scaling_configuration) are retired in favor of engine_mode = 'provisioned' with serverlessv2_scaling_configuration and aws_rds_cluster_instance (instance_class = 'db.serverless').

Notes & disambiguation

  • On December 6, 2024, AWS announced the retirement of Amazon Aurora Serverless v1, blocking the creation of new Aurora Serverless v1 clusters starting January 8, 2025 and reaching end of life on March 31, 2025.
  • Following the retirement of Aurora Serverless v1, official Amazon Aurora documentation simplified the product name of Aurora Serverless v2 back to 'Aurora serverless' (while retaining the aurora-serverless-v2.html documentation paths and ServerlessV2ScalingConfiguration API parameter).
  • Unlike legacy Aurora Serverless v1 (which used cluster-level EngineMode=serverless and ScalingConfiguration without DB instances), Aurora Serverless v2 uses standard provisioned DB clusters (EngineMode=provisioned) configured with ServerlessV2ScalingConfiguration and DB instances of class db.serverless.
