Can external servers access Alibaba Cloud ApsaraDB for RDS?

Last Updated: Nov 20, 2017

RDS supports accesses to Internet addresses, and users can access RDS through external servers. But we recommend you use ApsaraDB for RDS with Alibaba Cloud ECS because the network traffic from Alibaba Cloud server to RDS over the intranet will not produce any charges.

If your RDS address has been changed to the intranet address, you must switch it back to the public address in the Control Panel (a maximum of 20 switches are allowed every day).
