Private network

Private IP address

DDS provides a private IP address by default.

If your applications are running on an ECS in the same region and VPC as your DDS instance, you are advised to use a private IP address to connect the ECS to your DDS instances.

  • Secure and excellent performance
  • For faster transmission and improved security, you are advised to migrate your applications to an ECS that is in the same subnet as your DDS instance and use a private IP address to access the instance.

Public network

EIP

  • If your applications are running on an ECS that is in a different region from the one where the DDS instance is located, use an EIP to connect the ECS to your DDS instances.
  • If you use a third-party device or your local device to connect to a DDS instance, you can use an EIP to connect to the DB instance.
  • Low security
