  • Tests showed that there is slight performance improvement for DI itself and DI with CICO comparing xlarge and 0.5-128 ACU. Show more details...
  • For CICO itself and CICO together with DI there is no significant influence of using serverless configuration. Show more details...
  • Serverless DB configuration consumes more CPU and DB resources than RDS  configuration comparing Serverless (0.5 - 128 ACUs) and RDS db.r6g.xlarge configurations. Show more details...
  • Serverless DB configuration consumes less CPU and DB resources than RDS  configuration comparing Serverless (32 - 128 ACUs) and RDS db.r6g.8xlarge configurations. Show more details...

As a conclusion, there is no much degradation with usage of serverless DB. According to the results, it could be an adequate replacement for regular RDS.
