Overview

DAS

No IP address is required. You can connect to your DB instance through DAS on the management console.

DAS enables you to manage databases on a web-based console and provides you with database development, O&M, and intelligent diagnosis to make it easy to use and maintain your databases. The permissions required for connecting to DB instances through DAS are enabled by default.

• Easy to use, secure, advanced, and intelligent
• Recommended

Private network

Floating IP

RDS provides a floating IP address by default.

When your applications are deployed on an ECS that is in the same region and VPC as RDS, you are advised to use a floating IP address to connect to the RDS DB instance through the ECS.

• Secure and excellent performance
• Recommended

Public network

EIP

If you cannot access an RDS DB instance through a floating IP address, bind an EIP to the DB instance and connect the DB instance through the EIP.

• A relatively lower level of security compared to other connection methods
• To achieve a higher transmission rate and security level, you are advised to migrate your applications to an ECS that is in the same VPC as your RDS DB instance and use a floating IP address to access the DB instance.
• You need to purchase an EIP. For details, see EIP billing details.
