Oracle RDS Read Replica Cross Account and VPC using VPC Endpoints

Afraid it’s not possible with RDS to have another instance in another account.

The only way I can see this is possible is an external read replica hosted on an EC2 via vpc peering or TGW between both VPCs.

Hi,

This article details the implementation of what you want to achieve: https://medium.com/@anirban.ch.it/a-step-by-step-approach-to-setup-aws-privatelink-for-amazon-rds-across-vpcs-2ed69fc33f02

The corresponding official AWS doc is here: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/vpc-interface-endpoints.html

Best,

Didier
