Considering the use cases described below, it is assumed that there is little traffic in the case of production use. Also, since V2 is currently in preview, it cannot be expected to be in production. Considering these, the Aurora DB cluster is considered to be a candidate, although the cost is higher than that of serverless. https://aws.amazon.com/rds/aurora/serverless/
