Configuring Access Control

Scenarios

DDM supports load balancing by default, but some regions may not support. If an application accesses DDM using a private IP address, there are no traffic restrictions. To control access, you need to configure access control for your DDM instance. The security group is still valid for access requests directly sent to DDM nodes.

Procedure

After a read-only group is created, the entry for configuring access control will be moved to the operation column of the group.

  1. On the DDM console, choose Instances in the navigation pane. In the instance list, locate the DDM instance that you want to scale out, and click its name. On the displayed Basic Information page, enable Access Control in the Network Information area.
  2. Click Configure. In the Configure Access Control dialog box, specify Access Policy, enter the required IP addresses, and click OK.

    If read/write splitting is enabled, access control only takes effect for groups.
