We use private spaces in Heroku which support VPC peering into our RDS/Aurora cluster. We are not willing to expose our DB to the public internet so this is a must for us to migrate to Render.

Hi, I understand from support that this feature is what would be needed to eliminate AWS data transfer costs, when your Render region is the same region as your AWS S3 region for example. This would be really helpful.

Private VPC peering for existing RDS/Aurora MySQL/Postgres dbs in Oregon, etc.
