This topic describes how to manage Application Load Balancer (ALB) instances by modifying the configurations of ALB instances.

Modify the name of an ALB instance

You can modify the names of your ALB instances to better manage the instances.

  1. Log on to the ALB console.
  2. In the top navigation bar, select the region where your ALB instance is deployed.
  3. On the Instances page, find the ALB instance that you want to manage, move the pointer over the instance name, and then click the Modify the name of the ALB instance icon.
  4. In the dialog box that appears, modify the name of the instance and click OK.

Add tags

You can use tags to classify ALB instances by purpose or owner.

Each tag consists of a key and a value. Before you add tags to an ALB instance, take note of the following limits:
  • You can add at most 20 tags to each ALB instance.
  • The keys of tags that are added to an ALB instance must be unique.
  1. Log on to the ALB console.
  2. In the top navigation bar, select the region where the ALB instance is deployed.
  3. On the Instances page, find the ALB instance that you want to manage, and move the pointer over the Tag icon in the Tag column. Then, click OK.
  4. In the Configure Tags dialog box, select or enter a key and a value. Then, click OK.

Enable or disable deletion protection

You can enable deletion protection to prevent accidentally releasing ALB instances.
Note To release an ALB instance, you must first disable deletion protection.
  1. Log on to the ALB console.
  2. In the top navigation bar, select the region where the ALB instance is deployed.
  3. On the Instances page, find the ALB instance that you want to manage and click the ID of the instance.
  4. Click the Instance Details tab. In the Instance Property section, enable or disable Delete Protection.

Enable or disable configuration read-only mode
