Can I Access a GaussDB Instance Over an Intranet Connection Across Regions?

By default, 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 EIP, Cloud Connect, or Virtual Private Network (VPN) to connect to instances across regions.

• You can access GaussDB instances across regions using EIP. For details, see Using gsql to Connect to an Instance.
• Cloud Connect allows you to connect two VPCs in the same account or in different accounts even if they are in different regions. For details, see Connecting VPCs in 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 Internet connections. For details, see Connecting to a VPC Through a VPN.
