Can I Access a TaurusDB for PostgreSQL Instance over an Intranet Across Regions?

By default, TaurusDB for PostgreSQL instances cannot be accessed over an intranet across regions. Cloud services in different regions cannot communicate with each other over an intranet. You can use Cloud Connect (CC) or Virtual Private Network (VPN) to connect to instances across regions.

• CC allows you to connect VPCs in different regions, even if they are not owned by the same account. For details, see Communications Among VPCs of the Same Account.
• VPN uses an encrypted tunnel to connect VPCs in different regions and sends traffic over the Internet. It is inexpensive, easy to configure, and easy to use. However, the quality of VPN connections depends on the quality of your Internet connection. For details, see Connecting to a VPC Through a VPN.
