Amazon RDS Data API now supports AWS PrivateLink
You can now use AWS PrivateLink to privately access Amazon RDS Data API for Aurora Serverless from your Amazon Virtual Private Cloud (Amazon VPC) without using public IPs, and without requiring the traffic to traverse across the Internet. You can now submit your SQL statements to Amazon RDS Data API without requiring an Internet Gateway in your VPC. AWS PrivateLink provides private connectivity between VPCs, AWS services, and on-premises applications, securely on the Amazon network. Amazon RDS Data API customers can now use private IP connectivity and security groups to meet their specific compliance requirements.
