How does ECS access ApsaraDB for RDS through the intranet?

Last Updated: Jul 13, 2016

The public bandwidth of ECS is usually limited. If you access ApsaraDB for RDS through ECS public NIC, the system performance may be quite slow due to the bandwidth limit. Therefore we recommend you access ApsaraDB for RDS through ECS intranet NIC. Ways to switch to intranet on the ApsaraDB for RDS console are as follows:
1) In high security access mode, ApsaraDB for RDS supports both the intranet and the Internet. You only need to click"Apply for intranet address" on the ApsaraDB for RDS console;
2) Well in high performance access mode, ApsaraDB for RDS only supports one type of connection address. You only need to click"Apply for intranet address" on the ApsaraDB for RDS console to switch to the intranet address, and release the Internet connection address;
Attention: After the intranet connection is added, in case of changes to your connection addresses, you need to modify the database address of your applications, and the applications need to be restarted. Otherwise your application will not be able to access ApsaraDB for RDS.
