Can I Access an RDS DB Instance Over an Intranet Connection Across Regions?
By default, RDS DB 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 (CC), or Virtual Private Network (VPN) to connect to RDS instances across regions.
- You can access RDS instances across regions using EIP.
- For RDS for MySQL instances, see Using MySQL CLI to Connect to an Instance Through a Public Network.
- For RDS for PostgreSQL instances, see Using psql CLI to Connect to an Instance Through a Public Network.
- For RDS for SQL Server instances, see Connecting to an Instance Through a Public Network.
- 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.
